I can't seem to walk without crashing- This has always been a challenge for me. Feet too big all my life and the balance of a ball. Took forever to convince myself of clipping into clipless pedals for road cycling. I did it and love the pavement/asphalt. Just Lov'n it!! But MTB with cliffs, large rocks, medium- small rocks ...FORGET IT! Regular gravel, yes, I will ride as long as the holes are not too deep to get out of easily. I don't even attempt jumping street curves, did that too many times without success to just accept my abilities and keep my body in one piece for my true love of road cycling!!!!
