Thanks Guys.
I assume you meant clipless, I do use them. I do see some benefit in sprints, but it has only been some time. I am concentrating on not dying on steep climbs so dont think I use the advantage of clipless on climbs yet. I do wear proper clothing as well. Changing the rim and tires sounds like a big investment, but I take it the benefits are proportional according to you. Would changing just the tires have very minimal impact?
Also, I wanted to know, does locking out the suspension when there are some patches of bad road, cause any harm to the suspension?
