Ridley’s endurance-oriented Fenix road bike gets a new disc brake model for 2015. It’s an all purpose road bike, like the original Fenix, in that it can be raced or commuted, ridden in fast group rides or all day adventure rides. Now, it gets disc brakes, along with a few changes to make the disc models a bit more versatile.
“We really wanted a road bike that could do some dirt since we already had some dirt bikes (aka cyclocross) that could do some road,” said Richard Wittenberg, Ridley’s VP of International Operations.
To do that, the chainstay length grows 5mm, which let them add clearance for larger tires – up to 700x28c – along with a stronger braking side. The longer chainstays also improve chainline, a concern when stretching the dropouts from 130mm to 135mm wide. Chainstays for the disc version are 410mm to 413mm depending on frame size.
Up front, the fork gets a different layup to handle the different braking stresses. They’re spec’ing 140mm rotors front and rear, and they stick with quick release axles on both ends to keep it simple. In testing, they were able to get the stiffness they wanted without going to thru axles.
