    Boone 48T smooth running

    The larger chainring makes for a smoother feel and a stiffer crank. There's no way to measure it but I feel it. It seems that the chain doesn't make noise as it would when under greater tension on smaller rings. (Running 48x25)

    Did I say the ring was perfectly round?

    Beautiful

    Looks good, goes well with the bike's color.

    I, myself, would not compromise log/rock clearance like that however, especially with such a jewell (no pun intended) hanging low. But that depends a lot on where you ride and I'm assuming it works well for you.

    My thoughts, exactly. It sure is purdy, though.

    I am playing with the idea of something like a 39x24 instead of 32x20 on my 29er...

    thanks

    I'll try to keep it purdy.

    Relative to my 33T the ground clearance is less by 1.2" or 3 cm.

    (48 - 33 = 15 teeth = 7 1/2", divide by 2*PI)

    I think I'm used to choosing the best line over rocks anyway for the sake of the cranks. Unlike a regular mountain bike the ring is always protected (somewhat) by the chain. Logs? Titanium should be stronger than wood.

    Looks great!

    I tweaked a 44T pretty good on a log-over and I have a 13" high BB. Was running a 44 x 26 at the time.

    The trouble with common sense is it is no longer common

    Thanks, I might need help with adding a little color.

    Very nice ring but it wouldn't last out here on the east coast with the log piles, rocks and roots.

    Just this morning I rode with a gearie (3 chainrings) whose bike had essentially the same clearance as mine. So neither of us would do well out East, though we practice on rocks in So Cal.

    But what really puzzles me is how full suspension gearies can survive anywhere at all! I mean if you have 3" of rear travel then the BB can drop nearly 1 3/4". Do all the 3 ring gearies turn into 2 ring gearies? Or do they compensate by choosing smarter lines like a hard tail rider?

    My observation

    Most duallies out here drop the outer ring and go up to a 34 in the middle to make up for it (a little). Your right though, I had a 2004 Jamis XLT with 5x5 travel and you do lose a noticeable amount of clearance. That was one main reason for my switching to SS. That and I like the preditability of hardtails.
