Re: Which bottom bracket length is right?

the recommended chainline for particular cranksets is often 'wrong' for the rear hub/number of speeds in use, anyway. In point of fact the same chainline cannot be perfect for 5s, 6s. 7s. 8s. 9s. 10s. 11s in various hub widths, not without adjustment, anyway. IME, an MTB chainset onto a 135mm 8/9/10...

Re: Pimping a bike for sale

if in doubt about the suitability of a particular product, do what it usually says on the label; "trial on an inconspicuous area first". There are so many different types of finish on various metals and various kinds of paint that there are very few products that are likely to do much good...

Re: snapped axle or not??

hubs that accept screw-on freewheels do tend to break axles. If the two halves move independent of one another, that is a sure-fire sign that all is not well. Try to get a replacement axle with the exact same threading (probably M10x1 in a QR axle) and re-use the old cones. There is a pretty fair ch...

yes the cable just unhooks but you usually need to back off the barrel adjuster before unhooking (unless there is a QR on the brake lever).

Re: Which bottom bracket length is right?

worth mentioning that some shimano BB units still come with an aluminium LH cup that is a very slack fit on the cartridge unit. Unless you do something with it or replace it with something else, this means that the unit will probably work loose and/or destroy the DS threads in the frame. Having seen...

shows an unevenly spaced bolt circle. I'm not sure that anyone makes aftermarket rings to fit that, and shimano offer one choice only.

see

for actual measurements of UN55 bottom brackets.

BTW 113mm length not listed; I think I didn't have one to hand at the time.

Re: Best way to dry wet chain (post-ride)?

it is worth noting that there is a fundamental difference between using a water displacer on a wet chain vs leaving it to dry. If the chain is contaminated with salty water, leaving it to dry results in brine of infinite strength, that is incredibly corrosive. There are a few lubes that resist this ...

Re: Second Puncture+Rain= Problems

for heavy rain conditions, maybe carry a bin liner with three holes already cut in it, so that you can 'wear it' or use it as a tent? BTW if it is a raining and you get one tube away from having to start using patches, it is not a bad idea to pause long enough to patch a tube when you first see any ...

Re: Return springs in Shimano SLR brake levers – purpose, etc.

it doesn't really infer 'pushing' per se necessarily because the lever would, if left to its own devices, not sit at rest but instead hang down at a different angle, without the spring. The spring in the lever alone is enough to stop the lever from rattling over most bumps, which means that the tens...

Re: 'loose' V brakes

these pivots very commonly run dry and this causes wear/corrosion/seizure in the bushings. IIRC the inner part of the bushing is steel and the outer part is brass. A good dodge with conventional bushings (that pivot directly on the bosses) is to wrap a few turns of PTFE tape round the boss before re...

Re: Foldable and non-foldable tyres on same bike

if the tyres are the same model but one with and one without folding beads, there are only two differences 1) the folding beaded tyre will be slightly lighter and 2) the fit of the tyre on the rim will be different The latter point makes no difference when the tyre is inflated, and only really has a...
