SRAM XDR Driver for Cannondale Topstone 1 ó Formula hub?

Hey everyone,

Have to contacted a Cannondale dealer? That's usually the best place to start.

Next, you could try this: https://www.formulahubs.com/contact.php Using that link, ask the company directly.

I've swapped freehubs on a few wheels, and I can tell you it is often not as straightforward as it should be. Strat with the manufacturers and hopefully they can point you directly to what you need.

The lack of info on OEM wheels is frustrating. I have a set of stock wheels that came on my Cannondale SuperX and I have no idea what the specs are on them.

Formula does have a website with some products listed, so you could see if your hubs match any of these:

The other option would be to contact Cannondale directly or a local dealer and ask them.

I have wondered if I could run an XD driver on my wheels as well, so I'm curious to know what you find.

Thanks for the reply!

Yes I tried my dealer where I bought the bike, and they submitted a request on the formulahubs.com site, we're just waiting to hear back.
In the meantime I ordered a new hub on ebay with XDR driver.

SRAM 900 11/12 Spd XDR/XD 28H Rear Disc Hub w/Axle Caps for 12x142mm AXS Usable
Not cheap, but not terrible, either (C$212). My dealer said it's the ticket, buy it! He'll re-lace the wheel for a great price, so, what have I got to lose?
He's got adapters for the center lock to 6 bolt disc so that's fine, and it comes with the thru axle end caps, sweet!

Heaven forbid I actually know what hub's on my bike!

Will do! The switchover from Shimano to Sram is "all the rage" for some, Sram is just a bit more fun. More speeds. more gear range, easier to install, no wires, why not??

Even when they run internals from a major name manufacturers. Maddening. As I've gotten older and structured my household finances to support my cycling addiction hobby, I've virtually given up on OEM wheels. If I do buy a bike (as opposed to a frame), I promptly rebuild the wheels with "known" hubs. Added advantage, they are super easy to rebuild/maintain because getting parts for them is easy and easily sourced.

Great idea in rebuilding the wheels. I one point I'd have thought this was crazy, now I get it!

Here's my solution, coming in from Taiwan, I can't wait!

(sorry for the stupidly big picture)
