Ok so i've read about the differences between SPD & SPD-SL but i have one question hopefully with a simple answer (as if!). I ride a specialized trip-cross which i have put full road tyres on as i don't use it as a cycle cross bike. I had intended to use it on some light off road canal paths etc when i first brought it hence the reason for going for a cycle cross rather than a full road bike (if only i could turn back time) i also fitted some shimano spd MTB style pedals on it as i wanted to be able to walk.
I am now considering two things the first to buy another full road bike (maybe another thread for bike ideas may follow!
) but also switching to the SPD-SL type pedal as
i've heard they are better on road bikes for longer rides. As i am now riding between 50-100 miles at a time i was wondering if they make that much difference as i haven't had the opportunity to try any and don't want to fork out money for new shoes and pedals if it really doesn't make much difference.
