What We Ride: Colby Cardoza’s Klein Quantum

What’s old is new

A modern spin on a classic!

Name: Colby Cardoza aka Ratto aka Clamato

Position at TPC: Bicycle Buyer

What you ride: Klein Quantum Race

Why you ride it: For obvious reasons of course, that ice cream paint job, but pay no attention to that fat and luscious aluminum tubing. All jokes aside, I really love the look of vintage/retro frames with modern components. Old school parts look cool and may be period correct, but given that I’m a young buck, I can really appreciate the functionality of new components.

Fun facts: People here at the shop know that I buy, build, and then sell a bike before I can even ride it. This may be true, however I find a great deal of joy in finding frames I love and building them into my own unique pieces of “wall art”. So take a quick look at this beautiful rig folks, because it wont be in my possession very long.

  1. Well done Sir. I also like old frames but installing new components. I have a liking for steel frames. It takes me back to my childhood when I first started racing bikes at the age of 14. I am 60 now and still competing.

    • Brian, this bike is not currently for sale. However, I am more than willing to entertain offers. Let me know what you’re thinking.

      Talk Soon,

    • Considering how rare this exact paint job is, not to mention Gary Klein’s signature located on the downtube (see photos), I’d be happy to entertain offers around $2,000 for the frame and fork.

      All the best.
