SPD Spacers

gcwebbyuk

I have a left leg that is about 0.5cm shorter than my right, which is starting to cause me problems with saddle height.

I have seen that you can get spacers for road cleats, but I can't find any for MTB cleats. Any idea where they can be bought? The other alternative is to put a foam wedge in the heel of the shoe, but would rather go for an external spacer than make the shoe possibly uncomfortable.

Doubt I would notice 5mm, but could'nt you get different size crank arms?

Yeah I guess that is a possibility.

I notice the problem in two places depending on which leg I adjust the saddle for (and only really when on a turbo trainer seated for long periods). If I adjust the saddle for my longer (right) leg, I get pain deep in the hip flexor on the left hand side. If I lower the saddle to suit my left leg, my right knee feels awkward and sometimes uncomfortable.

I currently have it lowered to suit my left leg.

I have seen a physio who has suggested it could be my pelvis is mis-aligned due to a foo-bar lower back. He has suggested using foam under my heel for walking.

Are these "spacers" of which you speak not called "washers"?

I believe so. You'll struggle to make the current bolts fit with washers of that depth. They are also made of sterner than your average steel as well as having weird shaped heads.

TBH use road shoes and pedals easier to shim. MTB cleats cut into the sole so as not to move so you are going to have fun, not to mention the bolts.

and as it is only when on the trainer.

No better suggestions at the moment, good luck in your plight.

I don't set my saddle to within 5mm in the first place and never have a problem, so would suggest your issue is not caused by the 5mm difference.

You could try a 172.5mm crank on the short side? That would at least halve the difference.
