Anyone know anything about disc brakes?

Only noobs run their quick-release on the disc side.

'Trek has received reports of three incidents, one resulting in quadriplegia and two with lesser injuries, according to the CPSC.'

Oh dear :(

Christ :-/

Half our old customer bicycle tend to turn up with them tightening just the cam, they assumed that all that needed.

Thing about that skewer thought, is that it's not just Trek, but all bicycles manufacturer with the closed cam skewer.

Yep, nailed it. The QR is unfathomable magic to the non-bike geek.

Yep - it's coming. Fun fun fun. Especially for Cannondale after QR gate all those years ago.

Luckily we don't sell bike, but we do sell pitlocks...

More QR discussion on STW http://singletrackworld.com/2015/04/qrdisc-brake-recall-update/

So since 2000, 3 people have major injuries from quick release getting caught in the rotor.

The irony is that I found those closed cam skewer to be a lots tighter than the open cam skewer.

Would it be cynical of me to suggest that Trek recalling a million bikes and offering $20million worth of compensation might be less about customer safety and more about setting a precedent and pressuring other manufacturers - some of whom will not be big enough to absorb the cost of a recall never mind the cost of compensation that customers will now likely be seeking - to follow suit?

They've been doing recall recently on the fork and/or quick release of their Trek front suspension hybrids.

And now this.

I'm close to buying a Planet X London Road, that comes with Avid BB7 discs. Is it easy to replace them with TRP Spyres?

Has anyone done this? Is it worth it?

It will be totally worth it, get some compressionless cables too. Shouldn't be hard

Ah, okay. Thanks.

TBH probably not worth it tho. Spyres are better, but not better enough to justify the time / cost.

Doubt it to be honest. Trek aren't evil.

Really?

Nah, I was being facetious :-)

I just prefer not too, as it's nice to avoid a potentially hot rotor when you're undoing a QR.

Really? Maybe I should just see how I get on with the Avids then, and see in a year's (and a winter's) time...

Good old Planet X - only just releasing their perfect mid-range all-weather commuter! Still, it's a month ahead of their titanium version.

I dont agree with @howard, bb7's need constant adjustment compared to the spyres. I know people who have both, thats the general consensus

Shimano rs685 ftw

Well, no. BB5/BB7 needs some additional adjustment compared to Spyres but unless you are utterly hamfisted or riding in wet sand, it's a once-a-month kind of thing.

If I had a blank slate I'd suggest spyres tho. They are better. Just not so great that they would justify the cost and hassle of swapping from BB7 which is already a very good brake.

The exception is if you are racing CX*, but then I'd suggest upgrading to Hy/Rd if I was starting from BB7.

* Why? Because you can use an inline cable adjuster to adjust both pads with a Spyre, rather than just the actuated pad on BB7, meaning if you do race in conditions that destroy brake pads you can adjust whilst riding the bike. This is very, very rare though if you using sintered brake pads.

I personally wouldn't touch the avids with a barge pole. Everyone I know* who has them constantly gripes about how much faff they are. Constant rotor rubbing etc
I fucking hate noisy brakes if it was a bike is be commuting on it would drive me mad.
The spyes are super easy to setup and maintain and quiet because both pads move. Money well spent just to keep my sanity

*excluding scoble, but he's not people

I concur.

BB7s are the devil incarnate in disc brake form.

tosh

Meh, I've run BB7s with SRAM on mah airnimals for years. No problems. I raced CX on a BB5 with 105 controls and it punched above its weight. I've run BB5s and 7s on MTBs, never really felt wanting. Maybe I just have wrench mad-skillz then.
