Re: Cantilever brakes

I've lost count of the number of people who have moaned about their cantis, been advised by lots of people to fit Vs "because they are better" and a few that maybe they should service and set up their cantis properly. In many cases they have fitted Vs and been happy. But in order to do thi...

Re: [Brompton BWR] Removing left-hand side bearing race?

yes, the clipped 1/4" balls are the same in almost every SA hub going back to 1930-something, possibly longer. Some Brucey top tips; 1) Don't damage the labyrinth seal when removing it; you may find that a replacement part is differently toleranced and doesn't fit very well. 2) If the clipped b...

Re: Rim thickness - worn out?

if this dwg is to be believed the thickness under the lips is roughly between 1.25 and 1.5mm when the rim is new.

Re: Cantilever brakes

you need to say what levers you have before you can say whether any given brake is liable to be suitable or not. Very probably your brakes need a good setup and a good service, rather than replacement.

Photos of your current brakes/levers would be useful.

Re: Noisy DH-3N20; guessing game...?

I don’t know, I don’t really have any experience working with hub generators (at least not the electrical bit), but I’ve been meaning to post about my own XT hub, which has started making an intermittent-but-frequent low growling noise when my lights are switched on. I haven’t had a chance to inves...

Re: 10s chain cleaning - once more around the buoy

it sounds like you already have a method; in what way (s) would you like to improve it, exactly?

Re: Suntour Accushift question.

http://hilarystone.com/images/sale%20images/Other%20gears/OGS2-Cyclone-single.jpg the above is the correct style of gear lever to go with Cyclone Mk1 mechs, but other SunTour gear levers were used with these mechs too.

Re: Suntour Accushift question.

the accushift levers you have a) may work with the RD you have in the indexed mode despite not being meant for it (you have little lose by trying?) (*) b) may have a friction mode in them (usually selected by turning the knurled ring, where the centre screw (with the D ring) just secures the lever; ...

Re: Suntour Accushift question.

Cyclone MkII (eg 3700) was not an index-compatible group (launched in about 1982 I think); Accushift came later, and the RDs were completely different. If Cyclone MKII derailleurs happen to work with indexed levers (they might, you never know) it is an accident, I think. You can see Cyclone MkII RDs...

Re: Suntour Accushift question.

accushift shifters were indexed; 'accushift' is SunTour's name for their premium index system introduced in 1987 (they had a much earlier sort-of lever-indexed system but only on much lower groupsets, called 'the mighty click' or something) . Cyclone existed in several versions, not all of which wer...

Re: Old, old Specialized Rockhopper

better? We don't have much idea of what your idea of offroad is like, or your habits/preferences. Or what the rockhopper is like exactly, come to that. If the bits on it are original, (eg RD-M700 etc 'Deer Head' Deore) that era of bike is probably (at the latest) ~1987, so I'm guessing 3x6 non-index...

some HT-II cranks have had aluminium spindles. Dunno if this applies to current models or not.

Re: Park Chain Cyclone Cleaner

Just washed mine in the washing machine along with my smelly overalls. Stripped it down, put all the bits into an old tea-towel and tied it up with lazzy bands. All done and out of the machine, but the bag opened and the bits were all loose in the machine! :D All ok and all retrieved. The parts see...

Re: Rim thickness - worn out?

yes sort of, provided that braking (squeezing) loads and tyre width/ pressures are the same. Thing is, it won't be the case that those things are entirely independent of wheel size; the brakes squeeze the rim more often and (all else being equal) tyre pressures are liable to be higher on smaller whe...
