bmoto Posted September 10, 2017 Share Posted September 10, 2017 Hey all... I got some replacement fork springs. Went to measure them, and they're about 300mm on the money. Manual specs 305mm as stock, and 299.3mm = replacement. Should I be returning these? 5mm seems like nothing, except the manual says 300mm is an important threshold and these may settle in below that limit fairly quickly for all I know. Thanks in advance, b. Link to comment Share on other sites More sharing options...

pattonme Posted September 11, 2017 Share Posted September 11, 2017 unless you're a super-middleweight your springs are wrong anyhow... Link to comment Share on other sites More sharing options...
bmoto Posted September 11, 2017 Author Share Posted September 11, 2017 Nope. I'm 200 - without gear... With the stock springs, I'd crank the preload all the way in and still have 43mm of sag. Not bad, but... Went for a set of .90's to see if they can help - and it's the replacements that are at the minimum length threshold. Sticking with stock valving for now... thanks for weighing in! b.

pattonme Posted September 11, 2017 Share Posted September 11, 2017 I don't think any of the brand new Sonic springs I've sold have ever been 305mm. 300 or 301 perhaps. I can go measure my latest batch. 200lb + gear = 0.95 would be my suggestion but 0.9 should work just fine. It's a hell of a lot closer to correct than the stock springs.

bmoto Posted September 15, 2017 Author Share Posted September 15, 2017 Hey bud, thanks much. No need to measure them. If that's the way they're supposed to be. All good. Thank you! b. Link to comment Share on other sites More sharing options...

bmoto Posted September 15, 2017 Author Share Posted September 15, 2017 From Stoltec, who are great to deal with. But wanted to post the question here just in case there was an aberration. b. Link to comment Share on other sites More sharing options...
