"The problem mentioned above with track ends and disc brakes and rearward movement is easily solved – tighten the locknuts on the rear hub properly"
yeah we were aware that disc forces can cause the axle to shift in theory but in reality it only happened under hard braking if we didn't do the bolts up very tight at all. a tester got it to shift by doing trials-style lunges against the brake onto a small stump, but apart from that it's been issue-free and our resident team rider / ss nutter Paul has had no issues while riding 3 or 4 x what i could manage in a very busy year )
walla24, no need for a bolt-thru hub as in 12mm stds, just a solid 10mm axle with nuts or bolts i/o a QR axle. most if not all SS hubs have this now.
I think we're basically saying the same thing, james-o 🙂
[edit] I forgot to add – those of you who get a bit annoyed with the grub screws in the track ends might want to try what I did – I got the right size Nyloc nut and screwed it on to the end of the grub screw. It's not as neat as a Paul thumbscrew, but it does make it much easier to adjust the tension without a teeny allen key. It's one of the only things I want to change with my frame – get some nice thumbscrews rather than the allen headed grubs that it comes with.[/edit]
Oh, and a pic:
I originally ran my Io (a frame only I put bits onto, rather than a complete bike) with a Hope XC cassette hub with a Salsa QR. I had the hub move *once* under heavy braking after I failed to do the QR up tight enough. I've since changed to a DMR SS hub which can take bolts or a QR, and since it came with bolts, I used those – and haven't had a problem since.
I run Hope Mono Minis on this bike, and don't need to loosen the caliper before removing the rear wheel. I've run Oro K 18s as well, and they don't need to be loosened either. The Oros are easier to set up, as there's no need to shim the caliper, and you can align the caliper to the disk accurately when tightening the chain, as track ends do mean you can have the rear wheel ever so slightly off the centre line.
If you take the rear wheel out a lot, then track ends might not be the perfect option. I had to drop my rear wheel out yesterday to change the pads, and, frankly, once you know the drill, it's a simple, quick job that allows you to sort chain tension at the same time. It took me longer to find the spare pads than it did to change them out.
