Re: How to identify hydraulic brakes with auto adjust for brake pad wear?

The Juin Tech brakes are not, they have a seperate pad adjuster. cheers Yes sorry, i didn't read your post pro...

1895; 'perfection attained' they say. Well, at 22lbs with chainguard and mudguards, it would shame many modern machines. I'm not quite sure what they mean by 'double-tube pneumatic tyres' unless it is exactly literal; you get two chances before the tyre has to come off the rim (or be unsewn) for the...

Re: Vintage Bicycle Advertisements; good, bad. ugly...

the kangaroo was an early form of safety bicycle, in a category of its own known as 'dwarf ordinary', presumably for those who found the idea of a driven rear wheel a bit of a departure from the conventional. I can only imagine that there would have been a fair amount of flex in the frame where the ...

Re: Smaller chainset to use with Dura Ace 9speed

you would get an almost identical bottom gear ratio as what you propose by using 11-32 cassette (readily available) and using the extant chainset, RD (with a hanger extender). I think you would have slack running in the small-small gears but that this might be a tolerable arrangement. Cost to try th...

Re: 2.4W dynamo hubs

more poles/phases = 'better' = more expensive

whether it is a bottle or hub generator

If you don't want your lights to flicker at low speed, you can always turn them off and use battery powered ones instead.... :wink:

Re: Shimano 6 speed freewheel

the threading on the last cog can vary with the model of freewheel. Quite a lot of them are the same but there are variations. On the freewheel body there will be a model number. If you can read this it would help anyone to identify if the part is the same or not. No point in trying to find parts th...

Re: Smaller chainset to use with Dura Ace 9speed

with a standard cassette (i.e. one where every sprocket has its own splines onto a steel freehub body) you don't need the rivets to hold together; they are just there for assembly purposes. One way of getting the desired 13-36 cassette is to buy a 11-32 CS-HG200 and then to leave the 11T off and ins...

Re: Wanted - Recommendations for a new 8 speed rear derailleur

you possibly have an STX rear derailleur at present; if so it will have a model number on the back of the parallelogram. These RDs had adhesive decals which often fell off. Anyway any shimano 6/7/8/9s mech or any 'road' shimano 10s mech with enough capacity will work, ( excepting 7400 and 4700 serie...

Re: Smaller chainset to use with Dura Ace 9speed

you can get CS-HG400 9s in 12-36T which gives you quite usable gears using the 53T chainring?

Re: Smaller chainset to use with Dura Ace 9speed

it depends whether you view the RD or the chainset as being more fundamental to the groupset or not. Since any shimano 9s rear mech will work with your shifters and it'll be a lot cheaper than a new chainset, it seems like a no-brainer to me. I'm sure there is a way of coming up with a 13-34 or 13-3...

keep the chainset, get a more sensible cassette and RD....?

44/11 is about the same as 53/13

Re: Only 5Nm on a stem/handlebar clamp?

Who calibrates the calibrators? Read somewhere a while ago about inconsistent results it is not very difficult to check a torque wrench; you just need a lever and a weight. In critical application areas (eg aircraft maintenance) wrenches are checked almost before every use. For a variety of reasons...
