It was one of my ‘minus’ points when deciding to get the X2, but having run it for a good 6 months, I’m pleased to say I don’t miss the climb switch in the slightest. It’s now setup so well that pedal Bob is very limited (OK, DW Link on an HD3 might be helping here) and on tricky tech ascents the added traction is a bit of an eye opener. I’ve also not ended up hitting the climb switch, then ended up blowing so hard I forgot it was on and ended up a bit skittish in a big descent.
I’ve also taken the same view with the fork now, get it setup perfectly then leave it alone.
As for the CS upgrade, then at some point soon the X2 is headed into mojo for a good servicing. I’m actually pondering if I even bother asking how much the CS upgrade is as it’ll bring another faff element back into the bike. But then, if it’s only £50 or less then I’d consider it (I’ll be paying out for the service cost, and mojo usually chuck in any upgrades at parts cost only if they are doing a service). Either way, I’m certainly not rushing to get one fitted as the shock is so good in the first place.
