It might not look like much in its raw form with no context but to Firefly and their future customers who’d like to increase their tire size, while running a double crankset and maintaining correct chainline, this is the only way to do it. Above is Tyler from Firefly’s personal bike. This all-road was sent off to test their new yoke design, which will clear either a 700x42mm or 27.5x53mm tire with a compact road crankset. The team at Firefly have been working on this for some time now and it’s finally an option for those looking to optimize their drivetrain. Check out the technology section at their website for more information and see more photos of Tyler’s bike at the Firefly Flickr.
