Re: Servicing - brake issue

AlexH, you make a good point, I've assumed all hydraulic disks are dual piston and self adjusting. If they're not dual piston and self adjusting can the OP simply move the non moving pad (via moving the whole brake) further away form the disc to get less rub? I've never used single piston discs but ...

Re: Servicing - brake issue

Easy way to check if the brakes are centred with disc is to peek into the brake whilst gently applying the brake lever. When I got my first bike with hydraulic discs after a few Weeks I had a good look over it and noticed when I pressed the brake, one pad was almost in contact with disc and the othe...

Re: Project Pompino Alfine 11- if anyone is interested

Could the alfine be slimmed down any? It might make going from 120 to 135 a bit easier.
Every little helps?

Re: yet another stuck seat post thread....

on that youtube with the guy using a slidehammer that doesn't look particularly well stuck. If the seatpost was "really" stuck like the OPs i.e. hadn't been moved in it's life I imagine the saddle clamp would give way before the seatpost moved. My 2Ps worth to the discussion if the OP'er i...

Re: Dual Pivit brakes - different sizes

Not sure this will help but I've just put a set of the R559's on my new (to me) commuter, an 80's Carlton tourer I've setup as 1 * 8. The pads are quite high in the slots as the frame accepts 47-57 brakes and so dar I've only done circa 10 miles but so far but the braking is easily as good (if not b...

Re: Fork Dimensions

A section from rivbike's converting to 650b. "Step Two: Measure the front and rear wheelspaces. On a normal sidepull-equipped 700c road bike you'll get numbers between 350mm and 360mm. Most common range among, say, '80s and '90s steel road bikes with sidepulls is mid-350s. This means it uses a ...

Re: searching for one of Brucey's posts!

thanks guys but it's not of those. AFAIK
I think I'll PM Brucey and ask if he recalls writing such a post.
I was going to suggest it be added to "too good to lose" but I best find it first.

I'd forgotten about searching from Google thanks.

Thanks

searching for one of Brucey's posts!

Hi Folks, Sorry to ask such a silly question. Brucey wrote an excellent post/article explaining how to measure brake lever pull, I think it was based on measuring from the pivot to where the cable attachs to the lever and then use this info to determine the lever pull and if it will work with DP, Ca...

is 2.2 still the maximum tyre/rim ratio

I've read on the CTC library that a maximum and minimum ratios of 2.2 and 1.4 are reccomended.

Is this still the case?

For example if I wanted to use a 37mm tyre on 14m internal rim it would be approx a 2.7 ratio, is that too much?

Thanks

Re: 29" or 26"

Go Spesh AWOL, it seems so adaptable. It looks like it can do all you need it to i.e. mainly road but can also do trails.
The troll/ogre seems a little "heavy duty" for mainly road use to me.

Re: MTB forks and disc brakes.

I'd second a drum brake option. I used a shimano one for approx 4 years commuting into central London and found it very effective. as the important bits are internal they are unaffected by the weather. Edit - I remember the shimano drum I had fitted was considered so powerful by Shimano that they fi...
