Custom Crumpton Loaded with Zipp

NAHBS Display Bike also Helps Debut New Zipp SL-70 Aero Bar

If you love carbon fiber racing machines, the custom made Crumpton Type 5 on display at this weekend’s North American Handmade Bicycle Show is a sight to behold. We were honored to have this handmade beauty be one of the bikes to help debut our new Zipp SL-70 Aero carbon handlebar.


In fact, this Crumpton is a full-package Zipp, SRAM and Quarq bike weighing in at only around 14 pounds. Adding to his ability to customize frames for his customers, builder Nick Crumpton now molds his own carbon tubing. “Molding the tubes as opposed to having them roll-wrapped by someone else, it let us do a little bit of shaping,” Crumpton said. “We’re able to tailor the tubes to each individual rider more easily.

“I have a philosophy about laminate schedules for various tubes in a bike frame that give the kind of quintessential ride that my bikes have, and what will really change from one rider to the next will be just how much of that material do we use. The ratios of fibers running at particular angles barely changes, but I am not going to do the same amount of material or even diameter tube for a 4-foot-10 98 pound woman than I would for a 6-foot-10 300 pound guy.”

This particular bicycle is for a customer who loves high-performance riding (with plenty of climbing). All we can say to that is, happy riding!
