TRP U-mount Alternatives

[prebsy]

Recently got my hands on a Stevens Volt TT frame. It's a great bike and while the stock tektro r725 brakes "work" they have plenty of issues. Specifically the micro adjustment bolts on the front are hidden by the fork. On the Rear the pad holder bolts can't be used without taking the crank off. Both don't open wide enough to use my clx64's without rub. So it looks like I can use an omega X in the rear with their adapter but is there anything else out there?
