So I'm going to give a 29er a shot. Picked up a Small Racer X 29er for 850 bucks from backcountry.com outlet... too good to pass up.

Kicking around forks now. I know the RX in a small was designed around a 80mm fork, but I also assume with a 38mm offset.

Will using a 100mm fork, but with a 51mm offset even out the handling? I do not want a floppy feeling bike. Has anyone done this?

Of course, then I'll have to order up some new 15mm axle lowers at some point also.

Been discussed till the cows come home.
Verdict: some like it, some don't...very few have actually tried it.

Part of the 51 offset is supposedly in the lower legs(although I doubt anyone has messured it)...so if you want 15Q...just buy a fork that has that feature.

I have a G2 Fox that I plan on trying on a Leviathan I just built....but honestly, I've been to busy riding and love the DT Swiss that I have on there( that many said was all wrong for the bike....those "many" have never ridden one)

My suggestion:Buy the fork you want..put it on, set it up for you... and ride the crap out of it

size asylum?

I ran a G2 fox (@ 100mm) on my asylum and loved it.
What size Asylum?

The small RX and Medium Asylum are similar in that they were designed around an 80mm fork i believe.

Thanks.

I ran a 51mm offset with a different frame...

But it has very similar geometry and suspension design. I have an Evolve and ran the 100mm 51mm offset Fox with it and it was very floppy. Too quick of steering and never felt balanced. I know the frames are different, but that's my two cents for you. Ride it and see how you like it, you can always sell the fork for another. FYI, I started with a 38mm Reba and it steered slow, went to the Fox with 51 mm offset and i was sketched out, finally settled on a fox with the 46mm offset. That has been just perfect.

thanks..

What I'm ultimatly trying to figure out is...

since the bike was designed with a 38mm offset and 80mm fork (for the small RX)

will the 51mm offset even out the increased length of a 100mm fork and will the bike steer basically the same.

Years ago when I had a 80mm RacerX ( circa 2000 or so) and I put a 100mm fork on it -it felt floppy. But at that time the fork offset was the same.

So, if every 10mm of fork travel equals about 1deg HT angle then is there a similar ratio for offset increases. I know it comes back to the trail... but relatively speaking.

80 or 100mm per Titus

Below from the Titus site: http://www.titusti.com/titus09/racerx_om.php
SELECTING A FORK:
Your Racer X frame is designed to be used with a front fork that has either 80mm or 100mm (3.14 -3.93") of travel. Selecting the proper fork will keep the head angle, seat angle, and bottom bracket height at their intended settings.

The 'Quick Specs': http://www.titusti.com/titus09/qspecs.php appears to show the SM speced with 490mm A-C length fork (80 reba, possibly), and the M/L speced with a 508 A-C length fork. So, a 100mm F29 (500mm A-C length, as I recall) should be within spec.

I've set up my size SM 2008 RX29 with the F29 at 100 and 80mm--both were fine, though the 80mm allows for easier left-right transitions in the tight OR woods that I ride. Current setup is the F29 at 80mm.
