We have something extra special for our latest Collective Reward gear giveaway. Thanks to a generous donation from the team at CHUMBA USA, one lucky Bikepacking Collective member will receive a CHUMBA Terlingua Steel gravel frame in their choice of size and color. That’s a $1,450 value—our biggest giveaway to date—and we couldn’t be more excited for one of our readers to win.
For those unfamiliar, the Terlingua is CHUMBA’s high performance gravel frame, with a versatile geometry designed to take on long-distance bikepacking trips and cyclocross races alike. It features stainless steel Paragon Machine Works sliding dropouts, generous clearance for up to 700 x 50mm (2.0″) tires, and a custom blend of thoughtfully selected tubing. It’s available in a full range of sizes from 50-60cm and a wide array of beautiful custom colors.
The Terlingua is built in house at CHUMBA’s Austin, TX facility. As Vince Colvin, director of operations at CHUMBA, explains, “Building the Terlingua in house, in small batches, means we can take the time to artfully craft every single bike. We have our own fixtures for tube bending, chainring dimpling, welding, and mitering. Because of this we can deliver a wider diversity of geometry numbers designed to get the most performance out of each size of Terlingua. Every frame passes multiple quality control checks made by the same people you’ll talk to when you call to order.”
Want a Chance to Win?
Join our Bikepacking Collective by 11:59 PM on Thursday, October 17th, and you’ll automatically be entered for the Terlingua frame and many other prizes. By doing so, you’ll also help ensure the future of the site, will receive two issues of The Bikepacking Journal in the mail each year, and will have access to lots of other great member benefits like discounts and giveaways. We’re largely reader supported, and every member makes a difference.
CHUMBA Terlingua Frame Highlights
Paragon Machine Works Stainless Steel Hooded Dropouts
Allows for the shortest possible 425mm CX-style chainstay length and everything from 425mm to 445mm for gravel and bikepacking. It can run thru axle, quick release, singlespeed, and Rohloff dropout inserts.
Size-specific bottom bracket drop
Chosen per size to allow optimal balance point for the rider and bike and paired to size specific crank arm lengths. The drop is designed to give great clearance on the loose gravel and allow aggressive cornering on the trail and for cyclocross.
Seat tube angles, effective Top Tube, and reach
Designed to optimize the front center of the bike to lessen or eliminate dreaded toe overlap common with other frames in the category while not forgetting how best to dial rider position on the bike.
Thoughtful cable routing
For a clean aesthetic and function, smooth cable actuation on shifters and brakes, all mounted with custom CNC’d mounts that can be planned to hold 1, 2 or 3 cables. Cable free top tube and seatstays for easy shouldering.
Low bottle cage mounts in the inner triangle play well with half frame bags, a third cage mount in under the downtube.
Up to 700c x 50mm tires. CHUMBA recommends going with 650b when moving to road plus sizes above 45c for best performance.
Q-Factor clearance for the fancy stuff like SRAM Red, Shimano Dura-Ace, Easton Carbon Cranks, etc. Chainring clearance for up to 52/36T and 46T 1x rings.
