140mm dhx air (with air volume reducer to stop the sag on the back)
Sorry for the long anal boringness of this response…
So it’s a 2.1875″ stroke shock? The Enduro frame will take an 8.75 x 2.75″ (standard longer travel frame had 8.75 x 2.5″ shock), which would give you 176mm travel; an increase of 26% over what you have now.
Sag is important; if the volume reduction is there to prevent the shock “wallowing” then the switch to a coil shock will be a good +ve difference. I switched to a CCDB (expensive, but v. good) & reckon any coil shock you’re likely to bother with will be a vast improvement over the air can.
I’m more worried about the seat stays giving out, tbh
Stronger SX-Trail stays (part no.S101500001) still available from your friendly Spesh dealer, £90 rrp & only in black Spesh UK told me this week 🙂 Yep, found a cracked weld/sticker – God knows how long it’s been like that, but once you know it’d be foolish to continue riding it…
soak up some decent drop-offs
Your knees will do this with good technique, which leads to…
learn to be comfortable in the air

Might seem expensive, but by the end of the day you realise the money isn’t such a major factor and after a few months just what a bargain/investment it is
