Re: Dynamo Lighting - fit and forget?

I have heard of folk carrying a dark-coloured plastic bag around with them to cover up the standlight.... FWIW I think that fully discharging a supercapacitor is considered to be 'bad for it'; my understanding is that (like most forms of electrolytic capacitor), they need to be 're-formed' when they...

Re: Zipp 202's

some aluminium freehub bodies come with reinforced splines, eg the ambrosio/novatec 'anti-bite guard' (ABG). 'Tis often expensive though. https://i.ytimg.com/vi/eebSdNFZlGU/hqdefault.jpg This 'prime' branded one is cheap (about £25) and made the same way but goodness knows if it fits many other hubs...

Re: Dynamo Lighting - fit and forget?

By coincidence on the day you wrote this I was setting off on a tour running a B&M mini rear permanently wired to the dynamo but the front only on when needed. It lasted a day before failing. The website said it is overload protected, I didnt see any further small print. I just looked on the B&...

Re: Chain skip after freewheeling

I recommend using Hypoid gear oil in IGHs. Mixing either that or ATF with a #2 grease can make a half-decent Semi-Fluid Grease (SFG).

Basically you can use almost anything to free up sticky pawls but some lubes are thin enough that they won't provide good long-term lubrication.

Re: Never assume that a new hub is correctly adjusted

I have mentioned this before but once again; it is impossible to build hubs with angular contact bearings that will stay in perfect adjustment when a) the wheel is built and then when b) the QR is tightened. If you have hubs with (deep groove) cartridge bearings then they will (under the same circum...

Re: looking for bearings

'cycle quality' bearings as sold by weldtite are available quite cheaply; arguably they are just fine when installed in inexpensive bike parts, and given that you need lots of them, may be more economic to use, too.

Re: Rear mechanical disc brake adjustment on a bike with horizontal rear dropouts

if you back the cable adjustment off fully (and/or loosen the pinch bolt) and the outer pad still touches the disc, then you will need to move the caliper on its mounts. The detail is different but the procedure as per the Hayes manual (link upthread) can be used, plus there are various methods of s...

Re: Chain skip after freewheeling

if you have removed the freehub body from a Deore hub like yours, then you can pick the seal out of the left side of the freehub body, and add oil (and/or penetrant if the pawls are still sticky) that way. The LH seal is just soft rubber and will come out fairly easily if (say) a cocktail stick is u...

Re: Never assume

Indeed. I would go so far as to say without these adjustments there is no advantage to spending the extra dosh on an XT as opposed to a, say, Sora. Bit of a con really. Given the attention to detail I have seen on some expensive stock bikes I find it very hard to believe the hubs are routinely fett...

Re: Zipp 202's

if you are going to stick lots of miles on any set of wheels, you should expect to have to repair them when they need it. Obviously you can only repair them if you can get spare parts and it is only sensible to repair them if it is also economic to do so. If you can't buy spare parts at all, you hav...

Re: Condor Fratello / Spa Audax (Ti) for Audax & light touring

if it comes down to a coin toss, I'd probably take whichever one offered the best mudguard clearances for my particular intended use.

Re: Folding pedals

yes, you can do that. However a slightly unwelcome side-effect is that a lot of these materials release an acid as they cure; this may cause corrosion in its own right.

Re: Repairing a Brompton rack

I have repaired racks by taking a short length of steel tube and a) giving it a squashed end that can be drilled and bolted to the dropout and b) bonding the end of the broken aluminium strut into the tube using epoxy resin. A snug sleeve joint about 1" long will be more than strong enough. Thi...

Re: what is the purpose of these holes?

if you do a google image search for 'rohloff dropouts' you will see all kinds of weird and wonderful shapes. Mostly they are for looks rather than function, I feel. If the dropouts don't have to withstand twisting forces then cutouts are not a bad idea; campag record dropouts are both elegant and we...
