Afternoon,

I picked up a 150mm travel spring for my forks and swapped them over today.  Unfortunately it's still 140mm travel...hhhmm. I didn't take the lowers off as assumed it was just taking the top cap off and swapping. Can anyone enlighten me please? Thanks
Chris

You'll likely need to pull them apart. There might be a spacer or a roll pin that needs moving.

Thanks, found an exploded diagram so reckon you're right. Seems to be spacers denoting 130/140mm. I'll pop those off and hopefully sorted.

Cheers

Hi @dyna-ti,

Just measured my bolt and it's 8mm long thread and 4.8mm width. Assume that's an M4 8mm you're after.

Cheers

P.s. in case anyone was losing sleep, I removed the spacer and hey presto 150mm travel!

Such a great fork. Has so much traction over rough terrain. I took mine to Dyfi and was really impressed with it on my trail bike.

Hi mate, I have the same fork on my GT Zaskar currently at 130mm but I wanna go up to either 140mm or even 150mm. Which spacer on the diagram did you need to take out? Cheers

At a guess,

6E to make it 140

6E and 6D to make it 150

Not sure if you'd need a longer spring?

Cheers, yeah you can buy a 140mm or 150mm spring for it so I was gonna do that but not sure how much fitting was involved!

As bens said really. Fairly straight forward if I remember correctly. Drop the lowers, remove spring. Remove spacer and replace new spring. Fresh oil and should be good to go.

Rides really well. It’s a simple and chunky fork but find it nice and plush and pretty bombproof. I’m not a good enough rider to worry too much about damper tech
