Ever since I’ve had the Kinesis FF29 (about a year now), I’ve paired the frame with a set of Kinesis IX rigid carbon forks. I originally intended to use them for long XC adventures and bike packing, and swap over to suspension at some point, to create a more all-round trail bike.
I never quite got round to making the switch. I love the direct feel of the rigid forks. I love that as I pick up pace through tricky terrain, it feels as though I am juggling daggers. Pick the right line and all is well, make a mistake and… well, it’s best not to make too many mistakes. When combined with decent volume tubeless tyres, the carbon fork also had a nice degree of compliance, meaning that trail buzz is smoothed out and the ride is actually nicely comfortable, if not plush.
Obviously, there is a tipping point. Quick, rough descents eventually become a bit tiresome – a difficult balancing act between maintaining pace, skipping across obstacles and clattering over/through stuff, scrubbing speed to maintain control. I was re-introduced to arm pump at the bottom of a few long hills.
My original forks were QR, and while being excellent, possibly suffered from being too flexible; there was a bit of “flutter” under hard braking. Nothing that couldn’t be lived with, but I was excited to see that Kinesis now have a 15mm thru-axle version of the IX. I’ve now done a couple of rides on the new fork – both a few hours long and over a variety of terrain. The new fork is noticeably stiffer. Brake flutter has disappeared, and tracking over rough ground feels even more precise. Theoretically this should mean that the fork is less comfortable as well, but I’m not sure if it actually is. The ride quality feels just as good (although I haven’t done a back to back test to be able to say with any confidence).
I can’t see the FF29 getting suspension forks any time soon. I love the bike as it is. I love the light weight, love the single gear, love that it is ultimately compromised for much of the riding I do. The whole package though means that it excels at the niche I’ve built it for. And when I take it out of that comfort zone, it is all the more fun (at least until my forearms begin to burn).
