swopping to an air fork will save a huge amount of weight and change the handling a lot
i tried my cotic with a pike 409 coil u turns but hated it and only lasted one ride with them – far too heavy a fork for a steel HT imo, i finally settled with a set of 120mm dual air rebas with a 20mm axle
the problem you will have is buying a new fork that has a 1 1/8 inch steerer, 120-130mm travel and the 20mm axle
imo you’d best try find a second hand 150mm air revelation (with the 20mm maxle) that can have a 20mm travel reducer fitted – so you end up with a 130mm fork that fits the frame and saves you around 550g (1.3lbs) over your coil pikes
most new 130mm forks have a 15mm thru axle
