Both actually, but I meant the M12 one.

It IS a Trialtech ISIS BB If you mean the M12 one that's nearly 100g heavier, then no, probably not - but there were zero of those that failed...

Replace the threads: http://tartybikes.co.uk/product.php?product_id=10498&category_id=22 And get a pair of these in 3/8" so it doesn't do it again: http://tartybikes.co.uk/product.php?product_id=10568&category_id=523

You're doing it wrong

That's just because they are open bearing without lube - but it does mean you can have twice as many balls (titter) therefore twice the load capability. Kristaps - when you say the bearings are 'dead', what do you mean exactly? I find it hard to believe they are broken.

Not sure how I could improve after having not ridden at all for 3 weeks and getting back on mod for the first time in a few months, but thanks Mark has defo improved though, some of the techy stuff he can do now is nuts! Glad (most of) you liked the vid Cheers, Ads

Ok cool - if you could email those details over with the photos that would be great please. Also a couple of photos of the underneath of the frame (downtube and chainstays) and we'll see what Echo say Adam

I love it when that happens, someone breaks something and suddenly it's a terrible product Where did you get the frame from? That should be warranty-able I think, looks in decent nick.

Do it

You'll probably find out faster than me in that case Haven't ridden it yet and probably won't until Saturday... sorry!

Damn extra full stop http://tartybikes.blogspot.com/2009/12/speed-race-fans.html

Yep They are pretty cool! Rob - got somre more pics/ info here: http://tartybikes.blogspot.com/2009/12/speed-race-fans.html. I would say they are about 'middle' in terms of their position. Can get another pic if you like?

Kin 'ell, must have been hammered! Any pics?

Sprocket width makes no real-world difference with a good sprocket like Surly/Trialtech. I've never seen a Surly/Trialtech sprocket worn out, ever! Surly website lists the sprockets at 1.375" however they measure the same (33.75mm minor thread diameter) as all the 1.37" items (freewheels, other sprockets) we have in stock, and less than ENOs which are around 33.85mm+.

That's the lockring, which keeps the sprocket on the hub.

Built this back up last night (swapped brakes, pedals and bars over from my 26) and lobbed a Small Block 8 on the front to try. Weight is 7.86kg. Need to do some filming sometime soon...

Has the head tube on the frame been faced? If not, that should sort it.

Yes.

Nope.

Sort of. You DO tap to 'an' M6 thread when helicoiling, but it's M6 x 0.8 (non standard) rather than normal M6 x 1.0. So, if you have tapped out to M6 x 1.0, there is no way you can go back to M5 x 0.8 now.

Ben - you're doing it wrong
