I've been Googling this but all I find are threads where someone tightened their thru-axle resulting in freehub drag, and the universal answer is to replace the missing spacer/seal in the freehub.
Normally I would snug up a through axle to the frame without any real tightening, and then cam over the lever. On my wife's Rockshox the lever is quite easy to cam over, and probably insufficient if it was a standard 9mm QR.
My bike has 12mm axles, and ever since I put the new wheels into the new frame, I cannot cam over the rear axle lever unless I snug up the axle and then back it off half a turn. When the axle is fully screwed into the frame the lever is too tight to cam over. The front is a bit tighter than ideal but can be done up.
Is there any way to adjust the through axle?
Which 12mm thru axle? There are rather a lot of them.
Which frame? There are even more of these.
If it's a true cam it will tighten the rear as you cam it over so needs to be adjusted loosely before you close the lever.
If it's an expansion plug that the lever operates it should be adjustable.
Thru axle design went to shit when thru axles moved to non DH bikes
Its a Kinesis Tripster AT and their own brand axle. The hub is a DCR (independent wheelbuilder) Front axle is another brand but thats not where the main problem is.
Your wife's Rockshox can be tightened by either opening the lever and nipping up the 2.5mm hex headed bolt under it if it's the old type, or removing it, pushing the lever into the axle body, and turning it anti-clockwise a notch or two if it's the newer version. We need to know what type/make yours is before suggesting anything, a pic may be helpful too.

Thanks Coatesy, I was hoping there would be a similar method for my 12mm axle, there is a hex bolt under the lever but thought I'd ask rather than start messing with it 🙂
Yeah. but does the cam push the axle end cap (under the lever) down the axle to tighten the axle against the outside of the dropouts (pre-loading it) or does it expand the axle to stop it rotating in the threads/dropout?
if the former, it's a shit design and adjusting it isn't really going to help your issue.
If it's a 3mm head, rather than 2.5, it may be holding the lever assembly onto a hex shaft, so it can be removed and rotated into another position which may be more suitable.
