talked to transition bikes today, and have pretty much decided to pre order the bottlerocket. However, in order to have the bike for my colorado trip I am limited in my shock choice to the manitou options, a swinger 4-way coil, or the air option. Kevin at transition says he thought the coil pedaled more efficiently than the air, and required less maintenance. What do you guys think, oh, and the coil is roughly $120 less than the air.
