Quick Question - Brake Disc Compatibility
 

HI All,

I just got a Felt Virtue Sport, which has WTB SX-17 rims on the front. However the bike came with a 24" rear wheel with huge tyre, which i would like to replace with something close to, if not identical to, the front wheel.

The rear wheel has a Shimano FH-M475 rear hub, with 6bolt disc mounting. The brakes are Tektro Draco hydraulics.
Can i get this rear wheel (in Czech since i'm living over here): Wheel Here which has centerlock and use a disc like this Disc Here?

Will it work with the Tektro brakes? Are discs basically compatible as long as the rotor size is the same?

Thanks a lot in advance for any information or advice! :)

As long as the disc rotor diameter is the same, it should work. With a new wheel, you may need to re-align the caliper, but a 160mm disc is a 160mm disc (assuming yours is a 160mm disc). There are other disc sizes too, like 140mm, and 180mm. I've not seen anyone go through the trouble of installing a 203mm rear disc rotor.

Just keep in mind that your rotor from the 6 bolt mounting cannot be mounted to the wheel with the centerlock.

Yes the brakes should work with almost any rotor that will attach to the hub. Another option is to get a Centrelock adaptor like this one: THIS, and mount any 6 bolt rotor, although I have no idea what is available in the Czech Republic... I imagine that you can get stuff from other EU countries pretty easily.

I have a bike with Draco brakes and Shimano CenterLock rotors. It works perfectly. The cheaper Shimano rotors are for resin pads only. I avoid those. The ones that work with metallic pads will also work with resin pads.
