    Which front chain ring do you use?

    Just wondering which front chain rings you guys use most and particularly on flat smooth paved surfaces. I mainly keep it on the largest ring and use the rear cogs for shifting and only use the two smaller rings when I run out of rear gears. But I heard from somewhere that this is not the most efficient way for this type of riding. I'm talking about a mountain bike here.

    on a flat paved surface, like a road, I use the big ring, which is still smaller than the small ring on my road bike. If you are primarily on bike paths (it sounds like that from your description), then you will want to worry more about an even pedal stroke and cadence than the chain ring you are in.
    hope this is informative.

    Search 'cross chaining' -causes abnormal wear and poor shifting.
    I have only one ring front, 38T. The middle ring is safer to run full cluster.
    My 38T ring to 11T cog @ 80rpm is 21.7 mph flatland. 90rpm is around 24.something mph.
    I rely on the 11T cog to keep the chainring size down (clearance).

    hills, smoother trails, road i rarely drop from the 44 about the only time i drop to 32 is for the rough & rugged , in most cases it be no more than 18-32. I remove the granny ring from my bikes cause i never use them for anything , i feel they are useless for anything

    Bet your bikes nicer than mine though.

    42T for me, on a DH rig. looking to shrink it down to about 36T, there are only a couple of tracks here that really need such a large ring.

    Not sure why dh riders are posting about riding on the road. As someone else said you don't want to cross the chain too much. Other than that, ride what is comfortable. Spinning a higher rpm, once you get used to it, is usually more efficient and easier on the knees than pushing a high gear.

    I ride my Nishiki Cascade MTB mostly on pavement, but occasionally take it off-road. Until recently I had a 24/36/46 triple on the front, and found that I spent most of the time on the big ring. I changed to a 32/40/50 set up on the front, and so far I've found it better on the rollers and trainer - I haven't had a chance to try it on the road yet…

    I wish.
    No idea, offroad is usually climbing, I live at sea level on an island.

    24.7 mph @90rpm is road. The speeds I'm posting are using Sheldons gear Calc.
    I mtb, we don't use no stinkin' bike computers 'round here.
