Bendy or normal?

Bottom one was ordered (braze on).
Just paid £35 for a ten speed on my Roubaix too.

Definitely road. The levers however get very close to the bars before the brakes bite.

Well, it's on and works a treat. 2mm shaved off the bracket and I can back the pads off both sides. The mount is only eight quid so should I discover something else all is not lost. Still very difficult to set up with no rubbing on either rotors. I think flat bars and normal levers would be much easier.

Well started to reset the changer then realised it was dropping every time I shifted - turns out the thread is knackered where it bolts on to the braze on type clamp. New one on order

Yes I'd thought of the threads. When first installed I think it still pushed up against the rotor but without the squeal. I did the normal setting procedure but when winding the adjusters back out I could see the rotor moving outward as the pressure was released from the outer pad. Last night was horrendous the noise unbelievable, squeezing the brake hard stopped it for about fifteen seconds but the noise whilst applying pressure was even worse - deafening.

If that is the real cause, then a pair of washers between the black brake mounting bracket and the ISO mount on the frame should sort it.

Wrong direction

-take it to a good bike shop and have them face the disc mount using a tool like this;



cheers

Interesting tool that, didn't know they existed, but that would be another (more accurate) way of shaving some metal off.

Right, I've spent hours fighting with it. The rotor itself is probably clearing the fork by 3-4mm which means the calliper needs to go outwards away from the rotor too. It's at the end of its slots and the outside pad is still pressing on the rotor. The mount has been dropped off at the local engineers shop where they will take about 2mm off the inside surface behind the lugs hopefully that will help. I'll try and take a pic to explain more.

It's one of the problems buying second hand I don't know exactly what's been fiddled with. The bike although looking near immaculate is a pig at the moment. The rear cassette was changed from the original to give a better range, the rear mech was changed from 105 to XT I'll try and find what the chain is, could be it's a ten speed instead of a nine or something daft. I've never had a complete nuetral before where the chain will not mesh with the teeth on any other bike.
Thanks for your help so far

Seems good, tried re setting the calliper countless times, upping the spring tension etc. The rotor must be dragging the static pad in at speed (any speed). So far I'm totally unimpressed with them - absolute cock to be honest. It's on a Tandem with 700c wheels so there's a fair amount of weight/leverage to bring the rotor into contact with the pad. I imagine the wheels flex a little allowing this to happen plus I can't get the calliper far enough away from the rotor by maybe 10 thou.
When I release the skewer the forks spring apart - maybe I can add a spacer of some sort?

105 shifters. I have a chain catcher to stop it smashing into the frame. Could be the sideways play in the chain I suppose, everything else looks ok including the gap to the teeth. The cogs look like new, it all looks fine to the eye.

I've fitted Avid bb7 road discs with 203 Avid clean sweep rotors. Was running reasonably ok until I had the wheels out to change the tyres. The tolerances have to be so close particularly on the rear to make them work it's a joke.
Anyway, I cant get the static pad away from the calliper even when backed off completely - there simply isn't the leeway to move the calliper out any more. Are there shims available to ft between the fork leg on the skewer?

Lets have a look ..... it's got a shimano rear cassette nine speed looks like 105 and on the front it has a 105 changer with Alize 9/10 speed chain rings. The chain looks ok but I don't have a measuring tool. Previous owner reckoned it was new - it's a Tandem by the way. Chainging down I can get a complete neutral between the big ring and the middle where the chain simply won't mesh with the teeth. Sometimes the chain will throw off the inner into the frame but mostly I simply can't get onto the inner ring under load.
