There arn’t many bikes around with the Geometry VS Travel of the ST4… Orange are ahead of the pack.
Really you have to ride one to appreciate how good they are, on paper its ONLY 100mm travel, doesnt look that great etc etc.. but it is a unique bike at present.. That said, I think there are couple of other companies joining the Short Travel Slack geometry train.
The changes to the 2011 model do address the issues that some had with the older ST4 though and all good steps in the right direction, even the Trek fuel took a few years to get it right.
