Update with pics of it in my frame me and callum curwood was playing about with it last night and got it into my frame, pic here is what we did to make it fit and work 1. take the axle, driver and drive side bearing out of the profile, along with the end cap 2. pt all of that into the pro2 shell leaving the non drive side pro2 bearing in(im guessing the profile bearing will fit) 3. cut down the non driveside end cap of the pro2, all you need is the little silver bit on the end of the cap. put that onto the end of the axle. 4. and then put it into your frame The snail cams also work on the inside of the frame problems(there are always problems lol) 1. the non drive side snail cam bolt head will have to be filed down about a mm if that, so that the wheel can go more forward as it hits on the end of the hub shell 2. there is no seal on the non drive side so im guessing if you like to get your bike dirty you will go through bearings lol, but you could probilly get a cover off a non sealed hub. Thats about it really, im going to get it built into a wheel asap and ill get testing it i shall let you all no how it goes
