Re: What colour for my tourer upgrade & other bits

if the dynamo light bracket fouls the brake cable then a different bracket can cure that. This page https://www.sjscycles.co.uk/front-light-brackets/?page=4 has lots of which I quite like the look of this one https://www.sjscycles.co.uk/images/products/medium/42746.jpg which (if inverted, and used w...

Re: Ergo /Shimano

RD4700 has the same pull ratio as current 11s shimano 'road' RDs. The nominal pull ratios are very close indeed but different RDs have a (differently) non-linear movement vs cable pull and that is designed into the shifter to match the RD. On bench tests it was very close, but tests I carried out re...

Re: Grease nipple on Rudge Montague folder

I think they did make some changes on the later frames then; there is no way a UN53 would go in an earlier frame...

Re: Ergo /Shimano

campag shifters + shimano rear mech + 8s cassette is a workable system

campag shifters + shimano rear mech + 10s cassette is not a workable system.

shimano 9s and 10s do not have the same spacing

Re: Grease nipple on Rudge Montague folder

is the old one blocked? Even if the grease nipple is in good condition you will need a proper high pressure grease gun to force grease into that fitting. I have never had to remove mine so I don't know what size it is. I have a stash of both M6 taper thread and 1/4" taper thread nipples somewhe...

Re: 6703 chainrings on 7803 chainset?

you could try it out with the bits you have at present, before you invest in more?

Freewheel.


cassette


screw-on freewheel (certainly on the £250 bike)

the more expensive model has a cassette hub I think.

Re: Cable disc compatibility

not really. They will be a bit more powerful and a bit more spongy with a bit more lever travel vs more modern STIs with the same brakes. You are likely to find this setup highly irritating if you have discs that are not perfectly straight. FWIW I don't think much of those brakes; one of the many fa...

Re: Leaning bike, poor brake force, broken spoke

apologies if this is obvious but it only takes a tiny bit of chain lube on the rims to turn the braking bad too.

Re: Leaning bike, poor brake force, broken spoke

I guess I've been trying to avoid having to remove perfectly good bar tape etc in order to change the cable or do you think it might only need the inner replacing? If indeed the cable is the problem?.... IMHO it is always a) worth pulling the inner back and forth both ways to see if it is draggy be...

but in a brake (that develops any appreciable pressure), NOT so that there is a different pressure in each slave cylinder on a single circuit.

Re: Leaning bike, poor brake force, broken spoke

trying another wheel makes good sense to me. If you don't have another wheel, as a test, try turning the one you have in the frame. Possibly the brake cable needs fettling or replacing; bad cables are like little thieves that steal your brake force. The Son archetype rim is stiff enough that a wheel...
