Cable tension. Other than that, its a bit of black magic but cable tension would be my first port of call.

I did notice that the cable was a bit slack so pulled it tighter but did see the cable had started to fray slightly so didn't want to pull it too much. I'll need to give it another go but I fear I'm in the black magic stage to turning the adjustment screws quarter turns at a time

Well...that was a fun way to cut my ride short :eek:

grudas · 18 Jul 2016 at 13:24

looks fine to me

Crikey! How did that happen?

@Derek W - if the cable is frayed just replace it. There's no point trying to adjust it if it's frayed.

**** FT...that doesn't look good! What did you do?!

Really really sad news, hope she was wearing a helmet - not a dig at Chris and his advocation of helmetless riding, but more for the media fallout and finger pointing which will tarnish the media reporting if not (not that I've seen any).

I failed miserably to get out over the weekend, did a couple of dog walks and that's about it. My weekly mileage suffered... 41 miles total. Although I was recovering from the 75 on the sunday & have no commuting riding currently.

Big popular sportive around here this weekend (St. Michaels Hospice 'Wheelie Big Cycle'). Everyone and their dog did it, although I always miss it as it falls on the same weekend (usually) of when we go away for my girlfriends birthday... We didn't this year but with the house move and big sportive I did last week I couldn't get a pass. Maybe next year! :rolleyes:

Most I knew did the 60 mile. Although a couple did the 93, including Tim who smashed it with a mate! Impressive!

Conditions were perfect - hardly any winds, warm and clear although overcast slightly which kept the sun off. Kinda thinking I did the wrong sportive after my 70 miles of headwinds and rain!

EDIT: Eeeek FT! Scary! Hope it happened near home and not descending! Did it break or wear through somewhere and then explode?!

The rotor just snapped. It's gauged the frame a bit where it twisted (there was another piece of rotor not in this pic) but hopefully nothing major damage-wise.

I'd heard a slightly strange clicking coming from there shortly before it. I guess I know the reason now

grudas · 18 Jul 2016 at 13:44

what rotors were they ? - just to add to avoid list

FrenchTart · 18 Jul 2016 at 13:45

Ashima AiRotor

To be fair it had done over 12,000 miles..but I still wouldn't expect it to fail like that.

I've just ordered some Shimano Ice-Techs which I'll swap out asap.

was there any wear indicator on them?

It could send you flying over the bars that! I'd rather not risk it

That rotor looks like it's made of cheese

It does a bit doesn't it. The Shimano IceTech ones looks absolutely solid compared to that!

Not that I've noticed but I hadn't really thought about it tbh.

I'd read about similar issues in the past but supposedly that was an issue that was fixed with newer revisions of the rotors. Clearly not the case. That said, I'm not a light rider and I've put them through some abuse. Still wouldn't recommend them to anyone now though

Yup, it's weird how broken stuff looks like it's not very strong.

Hello i would like to say that i am now a proud owner of the new Btwin 700 AF road bike

This is my first ever road bike and looking forward to using it for commuting and leisure!

So what are we recommending now then...

Are 160mm rotors generally more 'sturdy' than 140mm? Or just marginally better stopping power (bigger suface area) with better heat dissipation (as I've been thinking)?

'Ice-Tech resin pads w/ fins' on the Diverge I'm looking at...

LBS matching the £1875 on it as the 2017 range has been announced. So they're getting one in for me... 2017 Replacement is £2500, exactly the same setup & different colour! :rolleyes:

EDIT: Welcome Jonney!

Evening all

Has anyone tried to download a map from the openstreetmaps for Garmin recently? I don't seem to be getting the second email.

I dont really think it's fair to blame the brakes. Rotors are consumable parts of the braking system, the same as they are on cars. 12,000 miles is a huge distance and I doubt any other type of rotor would have lasted much longer than that either.
One of the main advantages of disc brakes is that you can replace the rotors when they wear out rather than the whole rim.

Fair point. To be honest I'd really not thought about how many miles they'd done until after they snapped.

Just look at your nice carbon wheels and think how lucky you are that you only need new rotors and pads* and not a whole new wheelset

*You should get new pads with your new rotors even if the old pads have some life left in them.

True enough

I have some extra brake pads so I'll swap them out. I've got a feeling my front ones are contaminated anyhow.

I'm also going to bleed the brakes tonight. May as well and all that.
