I think it works really good on this bike. The bike is quicker with a 180mm fork, but not as good in rough terrain. I also ride with a 180mm rear-setup (standard 170mm).
Nope. To get 180 mm (7.0 in) rear travel, you need a shock mount set and a new rear shock with a longer travel . The kit allows you to change beetween 140-180 mm travel (5.3 - 7.0 in)
