I have no idea how big is too big. As the geometry on the SL is quite conservative 1 degree isn't going to change things too much. I recently changed the flip chip to the high position and there is a noticeable difference to how the bike Sits more upwards in comparison to the low positioned flip chip which the bike comes set at.I was wondering what type of trails do you mostly ride? I have often wondered how to put into words the feeling of a difference of 10mm in fork travel in terms of one degree slacker or less? How big is too big for a fork?
I ride constantly changing terrain with lots of natural obstacle features. Roots, rocks, technical climbs and single track exposed mountain. Never more than 4 foot in the air.
