THis fits this htread as well, some very nice bikes here. This is my Singlespeed OS Blackbuck 29er
First time I ride Avid BB7's, they work great even for my Clydesdale frame, but then Holland IS flat.
The Blackbuck is different, 74! deg HA and OS' own raked non suspension corrected fork
With a rigid 29er Singlespeed the whole is more than the sum of parts, such magical rides.
Since picking this up second hand all I did was add pedals and change the saddle and tires on it.
And rode it, and then rode it some more.
