![]() ![]() Many builders ( more than 100, says S&S) offer BTCs as an option, including premier builders such as Seven Cycles, DeSalvo, Independent Fabrications, and Waterford/Gunnar. The coupling is often stiffer and stronger than the tube on which it’s installed. This system adds about a half pound to a bike, and it is durable-S&S has reports of riders getting over 90,000 miles on their coupled bikes with no issue. CNC-machined out of titanium or steel in S&S’s shop in Roseville, California, the BTC consists of two interlocking tapered-toothed fittings pulled together by a threaded collar. The S&S BTC is the original high-performance coupler system and still the standard by which all couplers are judged. Courtesy S&S Machine Bicycle Torque Coupling (BTC) “We really needed to make sure that we designed hit the tolerances so that it can handle the loads of a bike, so it’s dead quiet, no dirt gets in, its light enough that it is not going to impact your ride quality, and you can pass cables through on the inside,” Smith says.Ĭo-Motion’s Trident employs four couplers to build a convertible bike that seats two (without center section) or three (with center section) riders. But, applying that design to a bike took special consideration. 22’s other cofounder, Bryce Gracey, calls it “scarf-style” interface). 22 design as similar to those used for race car roll cages. 22’s machined titanium coupler isn’t a unique concept or design connecting two tubes through a machined interface is an idea that Smith says has “been done to death.” He describes the No. Aesthetics were also a consideration “We really try to make our bikes gorgeous and timeless and sweat the details on how they look,” Smith says. (I’ll talk more about this in a moment.) That wasn’t possible with existing systems. Mike Smith, No.22’s cofounder, told me that the company decided to develop its own coupler because they wanted something that worked well with internal routing and a hydraulic disconnect. The coupler system is so sleek that it’s hard to tell a coupled and noncoupled No. ![]() The bike has a flush, interlocking coupler joined by a single bolt that can be tightened with a 6mm hex wrench-something most riders probably already have in their seat bag. 22 is known for its artful and clean bikes, so it’s no wonder that its bespoke coupler system follows suit. Number 22’s system is so clean it’s almost invisible. ![]() With fender mounts, the ability to fit five water bottles and a confident steel fork with multi-purpose mounts, the Outback TandM Break-Away has all of the features to keep you and your riding partner outfitted with everything you’ll need for your time out riding.This is a coupled bike.
