Hi there,
I'm about to replace my tired Fox RL80mm forks on my Stumpjumper HT 04 (disc).
I weigh between 70-75kgs - I like racing about uphill - downhill my wheels remain on the ground!

Typical riding is on the road from Edinburgh to Glentress (locked out), the Black climb (favourite bit!), then head down the red descent, then back on the road.
...also occasional loops out to the hills and maybe a summer holiday trip for a transalps type ride.

I've narrowed down the choice to Rockshox SID race, but not sure if I should stick to the 80 size I currently have, or go for the 100?

will it mess up the geometry? or would I benefit from them being longer/stiffer if 'sunk' down to 90/80mm ?


I've been completely happy with the current 80mm set up, but can I only gain with a 100mm?

Any advice would be appreciated!
