I posted a couple weeks ago about some different rims and wheels I'm wanting to get! I DID, and I love them! I bought the Spinergy Spox everyday wheels, narrow hub. Black spokes silver hub.

So I'm wanting to get a set of the D's Locks brake system, I have read lots of good! I'm running the Spinergys with an Quickie GPV chair. I know this brake system will work for this chair type and set-up. Is anyone else running this braking system?? If so what you think of them durability wise, strength, reliability?
