Forks too small for frame?

bobbydigital

So I built a little project bike but it feels like I'm leaning too far forward, it has 80mm a2 atom forks and I was thinking that it would be better with 100mm or 120mm forks ? I don't really want to extend the stem due to the limitations of the hydralulic brake hoses.

It's an Kinesis XC Pro frame but I couldn't find details on what fork it should have. I've been looking at 120mm Reba forks or SID.

Here is a picture of it (obviously). :roll: Would I be right in saying that the lower part of the rear triangle, chainstays should be straight and parallel with the ground?

Could try shorter stem, cheaper than changing forks.

Also no, you are not correct about the chain stays being parallel with the ground, more important is the bb drop, which is how much the vertical distance is between the line between the two axles and the centre of the BB.

Will look for a nice little stem and see.

I'll have to measure bb drop also, thanks.

A simple Google image search shows most XC Pro are running 100 or 120mm forks.

I did look on google but could only find the newer frames, the ones where the rear is made from carbon fiber and wasn't too sure if they had the same ergonomics.

I've bought a 60mm stem as that one is 110mm. Should be good.
