I've finding the clipless pedals a huge benefit in overall riding especially getting me up the hills and inclines going fast than about 4 mph. I live in central Texas (Austin) and there's no where to ride, literally, that is flat for any distance unless you want to go up and down a short stretch of road. Plus while we have more greenbelts than almost any other city, they are more geared toward mountain bikes or at least anything but road bikes. The trails tend being very rocky and narrow if not downright a flat out mountain bike only routes. I feel really good about using the clipless pedals while riding but I think the feeling of helplessness might stem from just knowing that I'm "attached" to the bike and maybe cannot get off quick enough if a situation arises where I need to do just that. I really don't know though.
I am familiar with the bike functions. I spent some time which being fitted riding on the trainer with the associate at the LBS walking me through everything unless I could easily shift, brake, etc. No problems there. I also spent two days riding it on the trainer in the house braking and switching gears then some time not only just on my street but going around my neighborhood going no more than three blocks from the house. I've never heard of counter-steering though. What is it?
