Sean over at Vertigo Cycles is getting into the pre-NAHBS excitement and sent over a sneak peek of the new single speed chain tensioner he made in order to build up a new belt-driven SS cyclocross bike he’s going to show off in Austin. Here’s the story:
I was prepping a CenterTrack driven single speed CX bike for NAHBS and couldn’t find any good looking chain tensioners that would fit the Paragon hooded horizontal dropouts so I whipped these up. They’re slick enough that I’m going to make a run of them and will have them for sale shortly after NAHBS.
On-the-bike pics and more design explanation after the break…

Sean says the end caps are bigger than they need to be, about 7/8″ versus standard about 5/8″, in order to make sure there was enough thread depth on the skewer ends for the tension screws. “The belt drive requires significant tension, I didn’t have any 7075 rod and I didn’t want to risk pulling the threads out of 6061 after spending a few hours making them.”
