I have these forks on my Alpine 160, as does my missus. The fork is immense and that is coming from someone who used to ride a Fox Float 36.
The Floats felt dead in the mid travel and only really came into their own when on our annual trip to Morzine. The 55’s are active everywhere and have made trips to places like Llandegla enjoyable where beforehand it was dull.
Where it really excels though is on days to Helvelyn or like last weekend on Snowdon. So much grip and not much of a weight penalty. Also, they look mint and get loads of positive comments. I can honestly say that the 170mm has not effected my HA and everything still feels ok on the climbs.
Hope this helps in someway,
All the best,
Lee.
