After 4 years of riding with mountain style cleats & pedals (SPD PD-M520), I've just changed to the more popular road style (Shimano Ultegra SH-R130). Before I was using mountain style on both road & mountain bikes that I own. Problem is, I'm not sure if I like them. Admittedly any change takes a bit of getting used to, but they are harder to release even though they're set on the loosest setting. Also I find engaging more tricky. The bloke in the shop said I'd get used to them. The good thing is they're easier to pull up with, which is good for hills & sprinting. Plus the wider surface area should make it easier on long rides.
Any feed-back & opinions from you are welcomed. Cheers.
