Anyone know anything about disc brakes?

203mm that's 3mm more than the 200mm I was expecting yay

There's a 200mm disc?

Apparently...

I saw a chap running 200mm rotors on the old style unicrown GDF fork once, must have had barely a 1mm clearance. He said he'd taken it off his tandem.

Does anyone else have issues with bb7 road and quick releases?
I am having trouble seating the wheel in the fork correctly
Does anyone have any advice or YouTube vid to watch?

Holding the brake on while doing up the quick release helps me, otherwise the action of doing up the quick release can end up with the rotor being misaligned.

Gotta have weight on the axle to make sure it's fully seated in the drop-outs.

My Avid BB7's make such a loud noise in the rain, can anyone suggest a way of preventing them from doing this?

New pads and/or rotor? If so, you'll just have to let them bed in. Otherwise, have you checked that the inner pad is adjusted properly? Tighten it by a few clicks and it should eliminate the squeal. As only the outer pad moves when you brake, if the inner pad is too far back, the rotor will bend and meet the inner pad at an angle hence the squeal

Upgrade.

Yep new rotor, old pads. Beginning to think I should have got new pads to go with the new rotor. Ok, I'll give that ago tomorrow. Thanks.

@Berrow did you bed the rotor / pad in? Using the old constant heavy braking down a steep drag technique?

If not, you might have an inconsistent build up of brake-goo on your rotor which causes the squeals.

I think I got it seated right!
I pop to my lbs tomorrow to double check.
Rode on this morning to work and it was fine.

Anyone Know of anywhere selling TRP Spyke at a decent price? There's loads of Spyres going cheap on ebay but no Spykes.

Not yet. I'm guessing they're a bit niche, as good hydraulics are cheap and luddites like myself can buy BB7s for very little.

I'm only one ride into mine so far and no complaints. Will do a long term review, after they've been abused for a few months.

Yeah I guess they probably are.

I've just had a spell of leaky hydros and also bled about a dozen brakes for mates recently so I'm over oil and dot for now.

I currently have one bb7 which is on the back of my mtb. Have had it on the front and it rubbed a bit. Probably due to me being a retro grouch and using 9mm QR axle so not the stiffest.

Maybe I'll just go for a bb7 on the front and put up with the " shing shing shing".

Buy cheap ebay Spyres and I'll post you a pair of these for a fiver if I still have them knocking around... http://www.chainreactioncycles.com/shimano-tiagra-r550-brake-lever-flat-bars-only/rp-prod34695

shing shing shing might be a slightly bent rotor
i had a shing shing shing and switched out the rotor, now no shing shing shing

@dicki it was when I was getting out the saddle and waggling the bike about n stuff.

@andy_k 2 Spyres is most definitely out of my budget. I can get a pair of bb7 calipers for under £40. I only really need one but the one I already have could probably do with new pads and rubberybobs so may as well get that pair and have some spare parts.

@dicki it was when I was getting out the saddle and waggling the bike about n stuff.

Yeah flexy forks and drop-outs.

what size are the little washers on the bolts that hold the caliper inplace, I dropped one and it rolled away somewhere in work to never be seen again...

A work colleague suggested rather than the traditional bleeding with 2 syringes and doing the vacuum thing, you can just flush the system by pushing 2/3 syringes through from the calliper, is this bs and surely not perfect?

That how I do it, easier and quicker too (especially in a shop where time = money), push in the oil, once the cup on the brake lever is half full, tighten the bolt on the caliper while pushing (but not too hard otherwise you'll make a mess).
