Can you adjust FKS (to fit a bigger boot)

I'm gonna say take them in to a shop. I am pretty sure (not 100% though) they have like +/-1 cm of travel, so depending on where they are mounted they might be able to. However, your forward pressure will have to be reset, so you may as well take them in anyways, unless you know how to set them

Yeah, I'm planning on taking them in anyway.. I just wanted to know if they'd have to do a complete remount.

Either way I'm going in. Thanks man!

You should be able to, the FKS heel peice has 20mm of heel adjustment.

^ like Blake said it depends how they are mounted. They have about 20 mm totall so only 10 mm either way but you can't always use all 10 mm because the heel piece arms begin to catch. Going 8 mm is going to be pushing it but may be possible depending on the boot. Full tilts for exams tend to catch as try Re quite upright from the heel. If they do need remounting its not going to be too easy either as your only going up one size. You can't remount both heel an toe in the same mount as there won't be space between old and new holes. You can maybe just move the heel or toe but you are going to have to change your mount position whatever you do.

7mm each way, not 10mm. So it depends if they were mounted correctly for your original boots or slightly too big as is often the case. Back the arms all the way out to the stop line and check forward pressure.

Is it only 7mm the Rossi rep assured me it was 10mm either way last season. Either way I would say useable adjustment is only like 1cm in totall.

Yeah just checked it is 10mm either way.

Yeah the max/middle/min lines on the arm barrels are 10mm apart but since those are angled it's effectively 7mm horizontal adjustment each way.

Excellent point, did not know that.

Thanks for all of the input guys, I'm going to take them into the shop tomorrow anyway because I do not trust myself with the safety of my knees/legs/ankles/feet
