Rode a heavy hybrid to work for years. Got a road bike last year for faster commuting and have been doing longer group rides on that with the hybrid rebuilt as the snow bike. I want to try fixed next. Lots of riders on group rides on fixies and it makes perfect sense for commuting.
Am looking for something good for my hilly commute, but that I could also use for group rides as well next winter. The Redline 925 looks good for the commute, but not sure I could keep up with the group on it.
