BMC track bike with colour coordinated raceblades...>>>>>>>>>
I have ridden MTBs since 1985 when did you first ride one?
Good luck riding a bike setup like that up hill. I would choose single speed for that sort of bike setup every time as riding up hills and any distance is not what it is made for. You are thinking of an XC bike I think...
I have gears on my jump bike, as I normally raise the saddle and ride it to the jumps/track. When racing, at times it has been useful having gears, I only ever use 2, one for start and sometimes shift up at bottom of start hill. Riding any distance on it at all is ridiculously hard work, but quicker than pushing it.
