102mm cranks on a 29er...good idea?

Rubix

OK, I had 127mm cranks on my 29er. The left one went kaput, so I decided
to go a size smaller. I ordered some 102mm cranks. Looking at them side
by side, there doesn't seem to be much of a size difference. I mean,
how much can 1 inch throw it off? Well, come to find out, ALOT!!!

I got them put on thru the LBS. Got home, aired up the tire, and tried
unsuccessfully 4 times to do a static mount. Normally, on my old
cranks, I'd nail it each time. Not so much with these. First thing I
noticed, leverage. Or should I say, the lack there of. When I would get
up and in the neutral position to start going, there wasn't much to get
me going, takes a little more umphf to get going. I rode down the
street and back, and it felt a little wobbly, but fast. I came in for a
stop, tried my usual maneuver, but the uni wanted to keep moving
forward. I hop off, and the uni keeps going for about 15 ft. Hmmm,
seems like all I've learned with my 127s is now out the door. I'm not
sure if or when I will tackle a hill or two with this thing, how it
will perform.

Now, was it worth it for me to move down a size to 102? Or should I
have kept it at 127? I know it will take me a bit to relearn mounting
and stopping with the 102, I just wanted to progress to the next step.

Just take some time to get used to it. It's much faster than 127's and
150's. I rode Uninam on it (www.uninam.net). It climbs pretty well.
