There is also a reason that the vast majority of roadies (that ride regularly) use clipless. These reasons do not dissappear when riding over dirt and rocks instead of asphalt.
Yes, clipless can be used as a crutch. I don't disagree new riders should start on platforms, and should learn certain skills on platforms. I started on platforms years back. I don't doubt your experience, you sound as though you have much more than me. It sounds like it makes your opinions one sided and heavy handed, though. Or it could just be your personality.
I just want everyone reading this thread to know that your statement:
is categorically and demonstrably false.
You can "deem" anything you want. Some people will ride better and have more fun on flats, some will ride better and have more fun on clipless. It will change from person to person, trail to trail, etc. ad naseum. Both are versatile enough to be used for a wide range of riding.
So please stop the condescending tone... just because one rides clipless does not mean one has not learned to ride one's bike "correctly."
And you don't have to say "clipless are usefull in certain situations" only so you don't sound like HS, you can say it because it's truthful.
for TECHNICAL trails flats are best... you have yet to provide a real argument that proves other wise. I completely agree that for normal flat/hilly not so technical sections of trails clipless are probably better. Back when I was a teenager and competed in trials competitions some hot head XC guy and DH guy with expensive full susension bikes and clipless pedals would always say "oh we can roll down that" or "ride over that" and for entertainment value we would say go for it. This was in the middle of a competition. Each time they went head over heals or washed out and could not click out in time. Had they had flats they could have jumped off, thrown a leg out, and many other things to maintain balance and stay on their bike or take a spill much safer. Only at the 2001 Worlds did someone not say something like that to me (and I attribute that to the fact that the sections were straight up scary for even a trials rider).
That is my opinion, sorry if I am stating it in a manner that makes one think I intend it as fact.
