Anyone else noticed the following with Time pedals?
Towards the end of a training ride, I decided to switch to the big gears, keep the cadence low and use this to stress the leg muscles a bit more than normal. The purpose was merely to give my legs a little taste of something different - I'll build in such sessions later in the year using bigger gears to build some strength endurance.
However, due to the much larger gear, I was using more force than I'd be used to (I have always favoured a lower gear and much higher cadence). I was using the lower cadence to also focus on the pedal stroke, and pulling up at the bottom of the pedal stroke.
However, I noticed that my heel was turning in at the bottom of the stroke (happened on each leg) and was more pronounced when on a rise when more force was being applied.
The application of force in the leg can be thought to run up the line that would be the centre of the foot - if the cleat was off line to this, you get a torque between the force from your leg and the resistance of the bike applied from the pedal. But the bolts on the shoes are fixed, there's no way I can see of moving the cleats sideways - unless I've missed something. Anyone any ideas?
Its been a while since i owned a bike with clip pedals... and they were spd type so i dont know exactly.
But surely if there is no give in the positioning of the cleat under the shoe, then surely this is a design fault. I would like to cycle with everything facing forwards to know everything is mechanically sound, but then i dont know many people that run in this way, which is obviously more aggressive impact-wise.
Maybe contact the manufacturer and get some advice from them ???
I believe there is a sideways adjustment - for instance, a cleat if placd on the left shoe, it places the attachment a certain distance from the face of the crank, but if placed on the right shoe, the foot will be + or - 5mm
I believe this is to accomodate for different hip widths, in that if you have wider hips, you'll find it harder to get you feet in close.
I'm ordering new cleats anyway, so will try look into the set up further.
It seems a little strange though that there is no sideways adjustment. You want to centre line of your foot, and hence the centre line of the force, to be through the centre of the pedal. If its not, you get a twist, which at best means you body has to compensate, and so you loose efficency...
I don't have the time pedals, but if I remember correctly, they were supposed to allow for some slight bit of rotation in and out during the stroke. This was to allow for correct individual knee alignment. I have some that don't do this, and had to get special cleats that allow for 7 degrees rotation to not kill my knees. Is this what is happening or are they forcing the rotation?
