In a case of recommending what you have etc ….
Whilst running rigid the Sherpa will take a 120mm fork. I have a SID for this when spring finally arrives.
Whilst the spec sheet says it will take a 120mm fork I have found my Skookum to run just fine with a meager 90mm. I would swap out the 90mm for 100mm but probably no more.
I didn’t get on with my Solaris. I should have tried it with a 120mm fork as 100mm just didn’t “feel” enough.
