    bigger fork ? M5

    I have been thinking about getting a bigger fork for my mach 5. as of now it is set up very XC which is most of the riding I do. I would like to gain some confidence in the technical downs. would it be more in my interest to put a bigger fork on the bike or change out my wheel set ? I am currently running a RS Revelation 140 15mm with Easton XC90 wheels. I'm only 125lbs. My bike is a small Mach 5. Feels a little low on the front end and wondering if 150 or 160mm fork would make a big difference. thanks

    I replaced the standard stem from a 120mm 5 degree rise to a 90mm 15 degree rise and that changed it for me. I came off a Stupjumper so was used to a slacker feeling front end. Mine is a medium frame so not sure how this would work on a small, don't know how yours is set up. It is still a fast steering bike but I like mine that way in single track.

    I am sure some people have gone to 150mm forks on Mach 5's but you might want to double check it does not over stress the frame with Pivot first.

    There's one in the pics thread that has a 170mm (don't recall the fork model).
    Have have a Fox Float 36 lowered to 150 on my small M5.
    Going down is great. But going up sucks. The longer fork coupled with the 50mm stem and a swept back bar makes it wonder and lift on climbs.
    I'm sure I can remedy that if the stem was at least 70mm.

    BB height is at 14" no sag.
