types of cliping pedals
i have been reading and have a understanding of clipless pedals, are there other names for pedals that clip . what other types of cliping pedals are there, so i can research them.
plus, can you pedal without clipping in, sometimes i ride with my 4 yr old and he has a bike seat. when i put my foot were it should be, the back of my foot hits the bike seat.
also what is the benifits of more expensive ones, i know the titanium are alot lighter, but do they spin easier?
shimano PD-M520 is this a good one?
i am looking at more touring rather than offroad, metroparks, light gravel,, i have a gary fisher marlin that is 11 years old about and in need of updating. but i do not want to break the bank yet, i have two young children with me so spped is not important, just nice easy pedaling.
