With my change to smaller crank arms on my tri bike the biggest change and benefit I have noticed is –
1. my pedal stroke is a lot smoother and I don’t feel like I struggle to get over the top part of stroke like I felt before. A lot more comfortable!
2. As a result of No. 1, my quads – especially near the bottom or area just above the knee cap is not as sore after the bike leg portion of a race or long hard ride.
3. Maybe most important and a result from both the above, my run off the bike feels a lot better when just starting and my bike speed has increased!
