Came on my Kinesis Rise. Measured sag, added air, tallied with sticker on the leg, set rebound central-ish. First ride, stuck down, badly, no travel left. Added more air, second ride, stuck down. Returned under warranty- presume Sram found something amiss as they came back fully service, lowers replaced.
Received back this week, refitted, sag, etc, added an extra 30psi as ride was all road.
10 mins in, no travel left… my hands are sore, forks are stuck down. Stop, unweighted they don’t extend ( even if there’s not enough air, they should extend unweighted yeah? the Rise isn’t that bloody heavy!).
Am I missed something in the set up of these forks? or are they just £500 worth of garbage!?
I’ve been using sus forks long enough that £500 would’ve got me some top notch forks and I’ve never encountered anything like this.
I know someone who also had dead out of the box 35s. They've been fine after the first repair though.
Sounds like air is getting into the negative spring and not equalising. Can you pull them up to full travel and have them stay there? Or do they suck back down again?
Try letting all the air out. Remove the valve core and sharply extend the fork a few times. It may make a big sucking noise and extend. Suggesting the air was stuck in the negative.
If that works it could be caused by a damaged oring, damaged air spring leg shaft or scratched internal of stanchion. Or even just too much grease blocking the port inside.
Either way. Probably another job for the warranty department. But might give you an idea.

Suck down again. When they’re fully extended, there’s about 20- 30mm of “sag” that feels dead when you pull them up. Like, you pull them up to 130mm and they immediately use that dead section up.
Will try the sharp pull up… incidentally,I did try that before the first time I returned them, but still with air in. Didn’t make any difference anyway.
Will try as you suggest, thanks.
They’ve been fine after the first repair though.
Mad that they aren’t, isn’t it. I wonder if they just stuck new lowers on and didn’t bother testing.
Check if you can still get Yari forks for £260 from CRC - if so it's well worth buying them, then sell the 35s when warranty finally get them working. I sold 1 year old 35 gold for £220, so not much price difference.
Yeah, I do plan to change the shitty things. I suspect it’ll invalidate my warranty with Upgrade though, so will check that first!! 😆 The discussion on monday will be whether I can swap these for decent, reliable forks (like Suntour or X Fusion!)
