I have a client with a leg length discrepancy of 3/8 inches. What are your thoughts on using a quantity of 4 Leg Length Shims? (The Steve Hogg's Leg Length Shims which are 3 mm thick.)
I know a custom shoe or adjustable cranks or a custom platform riser would be ideal...and more costly.
They say shim/wedge adjust for about haft the difference and position the cleat to aid in crank lever length to assist also.
Your thoughts?
In general, Leg length issues in this range - we build around half of the distance as you mentioned.
4 Leg Length shims would be closer to 1/2 inch.
Sight unseen (in general) I would try one leg length shim and perhaps an alternate stack of wedges with a 3/8 difference.
If the cyclist has no previous compensation this can be a relatively big jump. You can always add a little over time. Even a small amount is better than no compensation which they may already be used to while cycling.
Initially I would not jump to different length cranks or making something custom. We have a good solution that will work well with our current Leg Length Shims and Cleat Wedges - this also saves time and money vs a new cranks and custom fabrication.
