iii. In a white-out or when there are no features visible to line up on, you either need to "walk on the needle" as in (i) above or, use a companion to STEER as follows:-

Any inaccuracy in taking the bearing will be magnified when you follow it on the ground so it is important to be as precise as possible. It's good to have a firm surface to lay the map on so you can hold the compass firmly in place - sitting down or using one knee works well (Photo 3).

2024527 — How Long Can You Drive with a Bad Wheel Bearing? ... Some may say that you can drive for up to a thousand miles with a failed wheel bearing—but ...

Internal gear hubs usually use oil, but it's important to use the correct lubricant. Some hubs like the NuVinci hub literally are designed around the special oil they use. For other hub types, the grease doesn't usually matter.

Excluding the different specific functions where you need oil, rather than grease, then you don't necessarily 'need' any more than one grease. You could put Slickoleum inside your freehub, for example, or on your bolt threads, or lubricate your fork with 'bike grease'. And you can probably buy a generic grease made for mining, marine use, or whatever, that is more water-resistant than any bike grease. But different greases will do their jobs better than others, and for some jobs there's likely to be more difference between a good grease and a bad one, e.g., inside a hub (where you'd like to avoid excessively regular servicing), rather than, say, bottle cage bolts.

These methods show how to take and follow a compass bearing accurately. There are times when absolute precision is not necessary because you are following a linear feature on the ground such as a ridge or a stream. It is still good practice to take a rough bearing and to use the compass to keep a general check on your direction. This will confirm that the feature you are following is still the correct one and could prevent a major navigational error.

Freehub grease - this is sold with the note 'Hard to solidify under low temperature'. The datasheet is not too specific, but it's 50/50 synthetic and mineral oil, plus lithium soap and additives. It is recommended for some Shimano freehub bodies. Using 'premium grease' on freehub pawls is a bad idea because it's too thick and can inhibit pawl engagement. You need a thinner grease here.

Besides these other manufacturers sell different greases for the same job, often with different compounds. Different criteria will include:

Internal hub grease. This is with calcium hydroxide 5-10%, white solid lubricants 2-3.5%, & 2.5-4.1% bentonite, other additives and mineral oil. This grease is calcium-based for wash-resistance, and temperatures are not high.

There is a confusing variety of greases for various bike parts out there. I wonder if I can just disregard that and use a 'one-size-fits-all' grease (if such a grease exists?

Unfortunately it's not very clear which grease and additives is best, because bicycles are different from lots of other applications in that speeds are quite low, and temperatures not too high. Durability is likely to be important.

A compass like this performs two functions ‐ it is both a magnetic compass and a protractor for taking bearings. You need to attach your compass so that you can leave go of it without losing it and also use it to take bearings from the map and hold it up when following a bearing. A simple and effective method which can be used with any combination of clothing or equipment is a long cord which goes over one shoulder (Photo 2). When using the compass for taking or following bearings, you can slip your arm through the loop (Photos 3 & 4).

Both of you must have compasses with the correct bearing set. One person walks in front within the limit of visibility and follows the bearing. The rear person uses the front person as a "feature" to line up on (Photo 6). It will be clear to the rear person whether or not the front person is walking on the bearing or is drifting off to one side. Every hundred metres, the front person turns around for clarification from the rear person. If all is well, the rear person puts an arm up vertically (Photo 7). If drifting has occurred, the rear person points in the direction required to come back on course (Photo 8). This method is effective and doesn't slow the overall speed down very much.

Anti-seize - this is a soap-based aluminium complex grease with high solids. It's to stop corrosion/seizing on threaded parts, and specifically where two different metals are in contact (stainless vs steel does not count as different, aluminium vs steel does). It's not used for moving parts. If your parts are regularly maintained you don't really need it.

Some greases really are special. But in other cases the grease doesn't really matter. Since so many companies just say to use their approved grease, it can be hard to tell apart which applications are really special and which ones don't really matter.

Once you have lined up the two points, press the baseplate firmly down on to the map to keep it in place (this is why it is useful to use your knee). Rotate the compass housing so that the north arrow points to north on the map (ignore the magnetic needle). Make sure the lines within the compass housing are parallel to the eastings (the eastings are the Grid Lines which point north - they are called the eastings because they are numbered from west to east). Check that you have accurately lined up:-

Hold your compass in front of you with the Direction of Travel arrow pointing in whichever direction you happen to be facing. Keep holding the compass in front of you and walk your body around until the north end of the magnetic needle coincides with the north arrow in the compass housing (the north end of the magnetic needle on your compass will probably be coloured red and some compass needles also have "N" on the needle). It is your body that turns - not the compass baseplate. The Direction of Travel arrow now "does what it says on the tin" - tells you which way to go.

Go to a fairly large area of flat ground such as a football pitch - take your compass and a couple of black plastic dustbin liners which will go over your head. You need to take a friend to make sure you don't walk into anything or have any difficulty with the bin liners. Mark your start point and, with the bin liner over your head, set the compass to north and follow the bearing for 25 double paces. Then set the bearing to east and follow this for another 25 double paces. Continue with south and then west so that you have walked a square. If you have followed the bearings accurately and have been consistent with your pacing you will finish up at the start point.

Shadow+ RD grease. This is a specific grease for Shimano's clutch for their RDs. Lubricating these is required at regular intervals. This grease is 50-60% synthetic oil, 25-35% calcium sulphonate thickener, 10-20% additives, 5-15% mineral oil. Shimano says 'Twice as durable as Internal Hub Grease, which is also for SHIMANO SHADOW RD+ stabilizer. ' The clutches on RDs create a maintenance issue for the owner, and you could use anything, but it seems that the Shadow+ RD grease was introduced because of warranty claims on the clutch derailleurs - if you used a grease with inferior wash-out properties, such as the IGH grease, or something even worse than that then providing you regularly re-lubricate it then things will be just fine. If you rely on infrequent dealer maintenance, your clutch may be running dry. So higher performance greases, just as with cars, reduce maintenance intervals.

Oct 10, 2023 — Let's check out how a wheel bearing works and why it's important, and then move on to what it could cost you to get that bad bearing fixed.

'Premium grease' aka 'Dura-Ace' grease. This is a slightly mysterious substance, but a lot of people say it is 'similar to' or 'the same as' Motorex Bike Grease 2000. This has an NLGI of 2, which means 'normal' grease (thicker than 'soft', runnier than 'firm'). Motorex say '. Ideal for lubricating bearings, wheel bearings, joints and headset. Neutral to elastomers and seals and prevents galvanic corrosion.'. This is Ca-12-OH based, so like some of the previous greases, wash-out resistant and not a high temperature grease (rated to 120C). A lot of the time Shimano don't bother recommending a specific grease, but when they do, this one tends to be the one. Since this is essentially a generic grease, it doesn't seem like one you need to buy in a tiny pot for high prices, but you would want similar properties, most notably water resistance.

Also, some frame couplers specify special fluoro-compound grease, and it's best to follow the instructions or potentially ruin your frame from thread galling.

May 4, 2020 — The timing belt is the newer version of the timing chain. Timing belts operate much more quietly than timing chains. They're also stronger than timing chains.

Place the compass on the map with the Direction of Travel arrow pointing in the direction you want to go and then line up the edge of the baseplate with your location and the feature you want to go to (the magnetic needle has nothing to do with taking a bearing from the map and you don't necessarily need to be anywhere near the area covered by the map when you take a bearing). You can also use the lines which run parallel with the edge of the baseplate - it is often easier to see the detail on the map more clearly by using these lines (Photo 5).

Before following the bearing on the ground you will need to adjust it for the Magnetic Variation. This variation changes over the years. The area around Ben Nevis presently has a variation of just over 3 degrees while the Cairngorms are just under 4 degrees. It is not practical to set your compass bearing to more than one degree of accuracy so for much of Scotland in 2009 you can use 3 degrees (confirm that you are using the correct variation by checking the details on the map). To convert a Grid Bearing to a Magnetic Bearing you need to add the 3 degrees. Most compasses which are used for mountain navigation have an increment of two degrees on the compass housing - so add one and a half increments. Finally check that the bearing you have is similar to the rough estimate which you took at the beginning - this is your double check.

The common recommendation is Slickoleum, which anhydrous calcium-soap based with good washout properties, and which is slightly thinner than many greases (ALGI 1.5) http://slickoleum.com/specifications.html

Another grease-based product is carbon assembly compound, which typically is grease + silica, which adds friction to enable parts to grip with a lower torque. This is used with carbon fibre parts, which if over-torqued can fracture.

Roller brake grease. https://si.shimano.com/api/publish/storage/static/sds/en/pdf/roller%20brake%20grease-202008-ENG-GHS.pdf This is 70-80% synthetic oil, 5-10% MoS2, 1-5% talc, 1-5% propylene carbonate (PPC), 5-15% bentonite, <1% quartz. MoS2 ('moly) has very superior friction properties for sliding surfaces. Bentonite is the the thickener (compare with lithium 'soap grease', the standard thickener). Bentonite makes for very good melt resistance. Talc is a friction reducer. I believe the PPC is also thickening. You could substitute a similar grease rather than the manufacturer's, but clearly a generic grease that doesn't contain MoS2, is soap-based, etc. would be a bad substitute.

Hydraulic mineral oil - this is for disc brakes, and is different from DOT fluid. Anecdotally people use mineral oil including baby oil, and it 'works'. But Shimano claim that only theirs is good and others can destroy your brakes. https://bikerumor.com/2013/04/11/tech-speak-brake-fluid-break-down-and-implications-for-road-disc-updated/ Take this with a pinch of salt as there are bunch of hydraulic mineral oils sold specifically for bicycles and no complaints.

There are some applications where you should only use the approved grease and using the wrong grease really will cause a problem. This includes roller brake grease. This is critical to use the exact grease specified, and unsafe to substitute anything else.

ii. The most accurate way to follow the bearing is to identify features on the ground which are on your direction of travel. This obviously requires some visibility but even in relatively poor visibility there will often be sufficient features which you can still see. The features can be quite close to you, maybe 25 metres. Holding the compass so that you can look along the baseplate in the direction of travel and at the same time confirm that the magnetic needle is lined up with the north pointer, find a feature which lies on the bearing. It may be a rock, a clump of heather or a change in the appearance of snow or ice cover. Once you have identified the feature there is no need to use the compass again until you have reached it. You can also take any route around obstacles to get to the feature. It is essential to maintain your fix on the feature (it may change in appearance as you get nearer). If you lose sight of it then use your compass to choose another feature. The features you choose need to be between you and the final target you are heading to. It's no use choosing something beyond your final target.

BetterSense's answer covers many of the cases where you need a specific type of grease quite thoroughly; however, 'marine grease' is the most general-purpose grease that I've seen recommended for use on miscellaneous bicycle components (e.g. greasing a non-CF seatpost, bottom bracket work, headset greasing, repacking bearings, etc). I primarily do mountain biking; in road biking disciplines, there may be more specific greases for areas like the bottom bracket.

Before placing the compass on the map, estimate what the bearing will be (from your location to the feature you want to go to). No need to do this in degrees, the cardinal points will do, i.e. North; South; East; West or NW; SE etc. This will alert you to the embarrassing and potentially serious error of lining up the compass in the wrong direction or along the wrong grid lines - getting into this habit will mean that your bearings are always double-checked.

Of course, following the bearing isn't the end of the story - you also need to know how far you have travelled. This is discussed in Estimating Distance.

On the other hand there are a lot of applications where the grease doesn't matter that much. In that case I use boat trailer bearing grease, or if something lighter or cleaner is needed, white lithium grease. These include things like most steel threads including pedal threads, steel seatposts and quill stems, brake pivots, wheel and headset bearings, crank splines, cassette splines, etc.

The previous articles dealt with Setting the Map and Contour Interpretation. Using these two skills often means that you don't need to use your compass very much but there will be times when good compass skills are essential. The skills described in this article should not be used in isolation from those shown in the previous two articles and the forthcoming ones. It is not a good idea to simply set a bearing on your compass and head off across mountain country without incorporating all the skills which the other articles deal with (e.g. setting the map, contour interpretation, estimating distance, route choice). Build up your compass skills progressively on paths and other prominent linear features which provide feedback about the accuracy of the course you are following.

You now have an accurate Grid Bearing. Take the compass off the map and note what the bearing is. You can read it at the cursor which is in line with the Direction of Travel arrow. Be careful not to dislodge the bearing by allowing the compass housing to rotate unintentionally.

Free hub seal grease . This is not for freehubs in general but is specifically for Shimano's Microspline seals, and for specific seals there. The datasheet gives the same basic constituents as the previous one, but it might be different.

Internal hub maintenance oil and SG-S700 oil. These serve a similar function in lubricating the internals of Shimano hub gears, but different designs seem to warrant tow different oils. Other IGH will require oil as well, e.g. Rohloff oil

Anecdotally, the Park Tools general purpose grease that a friend of mine has appeared to perform nearly identical to the tub of generic marine grease that I have in my garage.

Cable grease - this is synthetic silicone-based oil with PTFE (Teflon), and lithium soap thickener. The obvious comparator here would be a dry chain lube, however silicone washes out easier, whereas a chain lube would tend to be mineral oil based. Petroleum products can damage plastics and rubbers, and a wet chain oil would attract too much dirt.

'• When assembling the freewheel body unit, do not apply grease or oil outside of the designated areas. This may cause the freewheel body unit to malfunction. • Do not wash the freewheel body unit. The internal grease may flow out and cause the freewheel body unit to malfunction.'

i. The least accurate way to follow the bearing is to simply line up the needle as described above and "walk on the needle" i.e. you are only using the Direction of Travel arrow to keep you on the right bearing. It is possible to be accurate with this method but it does require practice and most people have a tendency to drift off to one side or the other (personal knowledge of your "drifting tendency" is useful). You need to hold the compass centrally in front of your body with the baseplate horizontal and positioned so that you can see the alignment of the magnetic needle whilst at the same time look along the Direction of Travel.
