Carbon Wheels with tubs

willbevan

Hi guys,

Got two questions as bought a second hand bike with carbon wheels, included a picture

1. Tub tape or soemthing seems to be starting to show recently... (green lines around it below), is this something to worry about, do i need to change the tub? have i pumped it up to much (around 120psi)

2. Brake blokes are leaving marks on the rims, now seen this on some mates carbon wheels, but wondering am i using the wrong brake blokes (using the ones that came with the bike and presume they were right as i had read something about carbon wheels needing carbon brake blockes?) .. red lines around it below



Only slightly concerned honest!

thanks

Hi there...

In the green box is the base tape which is part of the tub where the glue or tub tape adheres. As long as the tub is well adhered to the rim around the circumference on both sides this isn't a problem.

In the red box - aaargh! THIS IS VERY BAD! Don't ride the wheels any more until you change blocks or inspect them and find the source of the problem! You need a new set of carbon specific blocks. It looks like the existing ones are crap and/or have flint or alloy in them. If you'll be riding alloy and carbon wheels, get another set of compatible brake shoes as well - much easier than having to prise the pads out when changing.

I'd recommend SwissStop Yellow pads - they come in Campagnolo and Shimano variants. Looks like your caliper is Campag - there are two Campag block fittings sometimes called 9 and 10 speed so make sure you get the right ones. They're expensive but worth it for taking care of your rims (ahem!) and braking effectively, particularly if you get caught in a shower or are coming down a big hill.

Thank you!

Any idea how i can work out if they are the 9 or 10? (the calipers are record, but not the skeleton variety)

Picy of my current shoes is here: (do i need to worry about the 9/10 speed blockes if im buying a second pair of shoes?)





have found one place already that sells them

Will get a second pair of shoes as you said, as only will be using those wheel racing i expect, not for any training

Question : Where can i get campagnolo shoes from, only place i've found so far are ebay :S, are there differences between cent, chorus,record on the shoes?

Current pad format is 2001 and later I think. I'm not an expert identifying 'vintage' Campag calipers I'm afraid!

All pad varieties listed here:

The Race 2000 SwissStop Yellows should work but I'd call a high end bike shop or two to check - I'd try Sigma Sports in Kingston or Condor in London. The Wiggle price is about the same from memory so you might as well just get a set from them over the phone. Campag also have good technical documentation on their website that shows exploded components with part numbers for all the bits. These guys should also know and carry the relevant bits:

Or here for advice:

On spare shoes, I've not had need to look but a buddy bought Centaur (I think) calipers and cannibalised them for the shoes. I'm not sure about shoe compatibility (between years or Record and lower groups) and whether this is the cost effective way to do it but maybe worth investigating.

FWIW Italian Cycle Products shut up shop last year, but Mercian Cycles in Derby are a good source for Campagnolo spares. As was said, there are two styles of brake cartridges - pre and post 2001. If unsure, there is a date-wheel stamped into the back of the arm, with a 2-digit number in the middle identifying the year. I also agree of getting a complete set of cartridge holders and pads for your carbon wheels - it's quicker and easier just to change the whole assembly
