Re: Switching handlebars: Solutions for quick cable interchange

Why 3?
My guess is rear brake, rear gear, front gear cables.
If you are splitting a frame into 2 (S&S joints), the front brake cable won't need splitting as the lever and brake are both (hopefully!) on the same half.

Re: Switching handlebars: Solutions for quick cable interchange

Moultons have splitable cable inners for when the frame is dismantled into its 2 halves, so these might work? Wouldn't work if you had an enclosed (ie. cable outer) cable for all the length of the cable runs. If you have flat bars with grips + brake/gear levers at the end : You could have those clam...

Re: wiring to rear lamp

I've done dyno wires round the forks as per pilgrim-cycles photo, and round brake wires (variously exposed inner/enclosed inner with outer). Around the brake cable is tidier in my view (artisitic intepretation, so no "right" answer). Just ensure enough spare dyno wire to allow for brake fl...

Re: Finding non-standard bib tights

May be lady shorts (for lady fit padding) + men's bib tights with no padding (for leg length)? I have never used bib shorts/tights, my untried perception is as well as getting the leg and seat right, you need to get the torso (braces/shoulder straps) right so your torso length gives the right amount...

Re: Peugeot with Reynolds 531 frame tubes ( info sought )

Re brakes, definately Mafac I'd say.. If I remember correctly, the brake arms are quite flexy, so set pads front end a bit too low, then things flex to the correct position when you put the brakes on. If the old pads have gone hard (rim wear, low friction/poor braking) but you want to keep the origi...

Re: Why is it always No.6?

In the case of the 7s, 1- 5 I think are stamped out steel plate (held together with a rivet/bolt or few). 6 & 7 are more 3 dimensional (includes built in spacer (no 6) and spacer plus bit over the end of the splines for the lock ring to screw up against). These 2 sprockets are forged I would gue...

SA 5 speed levers

This is the other business end to the jamming SA front drum brake topic. 5 speed hub brake (modern XRD 5(W) on a Pashley) + SA 5 speed metal thumb shifter style lever. I have adjusted the gears and it seems OK, so just a lever query. Is the thumb shifter lever just poor? Every time I adjust these th...

Re: SA drum brake jamming

Now sorted. I first looked at the cable which felt OK anyway. Ran some thin oil through it, and re routed it to avoid sharp bends (it had a tight bend near the handlebars - big basket near the lever + a bend to get it through the central hole in Pashley's headset mounted basket support/mount). This ...

Re: Making a bike frame! need answers!

Forks with some spring in them, a lot more comfortable - avoids excess road vibration on the handlebars. "Spring" here includes "rigid" (ie none suspension) fork blades that spring/flex to absorb road vibration. "Spring" is usually reduced if you have disc brakes, as th...

Re: SA drum brake jamming

Brucey, Pivots seemed to move OK both ends of the shoes. I'll check the 45 deg movement. I'll also double check the hub (drum) lining, there might be a small ridge (un-worn section of lining?) around the outside edge of the drum lining. I'll need to check if it is a small ridge or brake dust debris ...

SA drum brake jamming

As in the title, a front 70 mm SA drum brake jams (not always) when applied (and not necessarily applied hard either), rolling the bike back a bit releases the brake. Cable looks/feels/moves fine. Cleaned black powder etc out of drum (there was quite a bit by the axle). Filed shoe edges ("feath...

Re: Is this (disc brake adapter) going to be OK like this?

203 mm rotors on our tandem (BB 7 calipers) are pretty strong brakes (never asked for the stoker's 3rd brake).

Re: Stronglight inner chain ring bolts.

If you go down the M6 bolt route and need to shim the M6 bolt up to the chain ring bolt hole diameter, conveniently the M6 washers that come on (most but not all) V brake pad fittings are a nice fit inside a chain ring bolt hole. You will still need some spacer or other between the ring and the cran...
