Through axle / disc brake on a turbo.

bristolpete

Another thought on the disk brake questions being asked here, but would assume that moving to a disk only bike would render a lot of turbo trainers useless if you were a one only bike person ?

You can get adapters for through axles but check with the model you plan to get.

Don't know why disc would upset things ?

My disc Defy doesn't mount on my Flux....not thru-axle either.

Figured as much.

The latest raft of through axle bikes render a lot of quality turbo's direct drive or otherwise moot. Another thing to think about if you have spent big £££ on a smart turbo.

The Direto comes with 142mm thru axle adaptors, which typically means another ~£50 with some other turbos, Cube* fits fine (as long as I remember to change to 11/12T sprocket to remove/install from/to turbo, otherwise the derailleur cage clearance past the turbo chassis is a no-go).

Did an instinctive press of brakes one time to stop a Zwift session, thankfully I realised my blunder part way through the brake lever range, so I could use a tyre lever to pry apart the rear brake pads! :oops:

* Pretty sure Cube don't cover frame damage from turbos, I might end up buying a bike (that better half can use?) for turbo use before next winter.

Anyone with a thru axle disc bike and a decent turbo is also likely to have another bike that can be used on the turbo. I have my old tarmac on the turbo. The frame is a bit battered, Its got a ultegra groupset thats done 8000 miles, no brake calipers and £15 wheel from e-bay. I figured it was more cost effective to do this than ruin the dropouts and sweat all over the good bike(s).

Unless the disc bike is the second/winter bike... I wouldn't be keen on using best bike on it.

I’m surprised that you think a group set that has done 8000 miles is battered enough for turbo use only!

Canyon Disc bikes do not fit on any trainer even with adapter. I had to keep my old bike for training, I had costed in the new purchase selling the old one for £500

Plenty of people use decent bikes on the turbo with no worries. My TT bike lives there until in racing it - done it for years and no bother.
