Legs hurting with spd sl pedals

[Marcus Aurelius]

Hi,

The main point of the SPD system is that it improves your pedal dynamics, hence the name Shimano Pedal Dynamics. Essentially it allows you to actively pull through the entire pedal stroke, rather than just effectively having your foot as a ‘passenger’ for half of it.

Track cyclist pull up Hence the extra straps.
You might pull up for a fraction of your time, but practically it is seldom.
This is due to the very small muscles that can pull up.
I used to pull up when I was younger for a fraction of the time sitting going up along hill.
And I do it for about 20 or 30 seconds On my normal training run Which is 2.5 - 3 Hours long.
I Normally only pull up at all for a short time When I can't be bothered to change down.
I use clipped pedals not clipless, never thought I was lacking anything?

can you support what you said with a link?

I don’t know about links, but watch any pro riders feet very closely, and you’ll see that they almost always roll their feet around the entire stroke, and not ‘flat foot’. This is how they get the power they need.its not so much ‘pull up’ it’s more ‘pull over and through’.

Thanks guys. I put the cleats back as far as they could go and it made all the difference. Back to normal again.

I'm a trendy consumer. Just look at my CLT-L09 using hovercraft full of eels.

Rule of thumb is the ball of foot should be over the axle.

Rule of thumb is the ball of foot should be over the axle.

It's not actually a very good 'rule', though - it's inefficient and can lead to soreness. Steve Hogg has a lot of interesting stuff on foot position:
