My 2017 Niner RKT has a HTA of 70*, with a 120mm Fox fork (71* with a 100mm Fox fork). The trails I want to ride now have longer, more rocky/technical descents that what I was riding before and this geometry is not very confidence inspiring, especially after eating it bad enough that I cracked a helmet. Other than this problem, I like the bike's geometry, I invested quite a lot in the buildup and fine tuning it, and it's in great shape so I'd hate to have to sell it when it still has a lot of life for me.
The bike has an integrated headset (from Niner specs: 1.125" x 1.5" tapered integrated "Campy style" Cane Creek IS42/28.6 IS52/40). I saw a company that put out an adaptor for this type of headset not long ago but it's made for headsets with IS41/28.6 at the top, so it's not compatible with my frame (Slack-R). The difference between the IS42 and IS41 is 0.8mm. It's a long shot but... I'm wondering if anyone knows about a spacer 0.8mm thick that I could fit between the frame's upper "cup" and the IS41 part.
I've dig some and found put a higher profile front tire (not sure that'll do much though) and change one or both bolts on the rear shock to shorten the eye-to-eye distance of the shock. This is supposed to change the HTA by 0.5-1.5 deg on bikes that have long travel rear socks (DH/Enduro) but my RKT has a 90mm shock, so the effect would be much smaller and I'd shortening the already short travel rear suspension.
Any other ideas on how to accomplish this?
