Hi All,

Just built this bike a few days ago. Was wondering, the travel of the fork is
100mm but i think the frame is designed for 80mm. Do you think the angle is weird?
I love the extra travel though.

The handling will be a tad slower through tight technical sections, but the benefit will be a little more stability on downhill sections. 100 mm is o.k., 130mm would've been too much!

my bike came with 80mm crappy forks. I put some five inch (130mm?) on there and then reduced it to four inches. I don't mind it at all. it is choppered out but when riding it I can't tell too much. I love to be able to just plow into small logs and have that front end just suck it up.

people may tell you it's not right or the frame wasn't designed for it and while that may be true, it won't stop you from riding it and having a good time. I personally ride a piece of junk bike compared to the people I ride with yet I can ride just as well, if not better, then they can. it's not the bike as much as it is the rider. if you like it, it's good.

have fun!

A 100mm fork should only be about 20mm taller than an 80mm fork. Also you should have more sag with a 100mm fork so it will be less than 20mm taller when riding. I have never really noticed the difference.
The ultimate test is to ride it, if it feels ok it is.

Looks like a good build to me. I prefer a slack head angle but I'm probably in the minority.
