Renn, RotorUSA
(Q-rings
), ZeroGravity..
I bought a used Renn disc that UPS put a hole in
(something in that truck must've been long, pointy and not well packed...
). Of course UPS says insufficient packaging
(double boxed, wheel wrapped in bubbelwrap, plus all space filled with peanuts... go figure
) and denies any claim. I contacted Renn to see if they had something like a crash replacement
(being 100% honest that the disc was used and damaged in transportation
) or if you could replace the disc part reusing the hub and maybe save a couple of $. Frank Rehnelt asked me to send him the disc so he could look at it... two weeks went by and I got a delivery from FedEx... Frank fixed my disc for FREE AND PAID shipping back! Not only does Renn have a great product, but with service like this... customer for life.
I bought a pair of 52/36 Q-rings for my tri bike
(Look 496
) and no matter how much I tweaked the front derailleur, I couldn't get it to shift correctly
(it either rubbed on the big ring or on the small ring
). I contacted RotorUSA and they suggested different ideas to get the derailleur set up. Not working... so they asked me to take a couple of photos and send them to them. Then I get an email asking for my address, they think they might have a solution that they want me to try. In the mail a week later, I have an aluminum spacer that moves the derailleur back just slightly, giving me enough clearance for both the 52 and the 36. For free of course!
I have ZeroGravity brakes on one of my bikes
(and my wife has a pair on one of her bikes
). The problem was that the brake shoes hit the inside of the fork on my Colnago. I emailed ZeroGravity and they custom made a spacer in titanium to move the brakes forward, creating clearance. To the store should be added that I was in Sweden at the time, but no problem... mail gets here as well!
