    opinions on airborne's B-29?

    ive been thinking of a ti frame for a while, and was looking for feedback on the airborn. looking at an 18 or 20 and was wondering how they ride in the tight rocky, rooty stuff. seems way different than the monkey in terms of wheelbase and ht angle. any bigger guys or gals out there riding these? are they very stiff? guy who answered airborne's phone said he's never ridden one of their bikes, so he couldn't tell me anything about the frame really. also, im on the cusp between sizes. fit the 20 on seat tube, and the 18 is more like the 26er top tubes im used to, but would be flying about a foot of exposed seatpost. riding a large monkey with a 110 now, and it fits fine. seems to be alot of these b-29's around, but not where i am. come to think of it, ive never seen a 29er where i am, except mine. thanks, all,

    I had an 18" and at a bit under 6', I too was on the cusp of sizing for the bike and had to ride with the 400mm post at the limit. The bike handles very well in all situations. The design of the bike was done with alot of input by Mikesee and it shows.

    For an off the shelf Ti frame it is a pretty good deal, but it is not the lightest frame out there though as the stock Fisher frames are lighter actually. If you can I would go with the 20" and run less post.
    A bike by any other name is still a bike.

    do you think it is stiff enough for a 200 pound rider, or do they have that wiggle that some ti frames have? did you ride ever try yours with a ridgid fork like the km?

    I was a little larger than the largest size, so I went custom which is an option by Airborne. I'm 225 and find the frame reasonably stiff. I only use the term reasonable because there isn't enough room between the chainstays to accomodate the flex and a Bonty 2.2. I've had no rub issues with the Klaw or Mythos.

    I don't think the frame is overly flexy. It uses considerable ovalled tubing to reduce flex. I've had it for about a year now as my primary bike, but its starting to turn green because of the Titus.

    Bigwheel- did you have any rub issues with the 2.2??

    the bike seems to have a long wheelbase. do you find it very hard to manage in the slow, tight, rocky stuff? or is more of a straight line racer? i know it is the rider not the bike, but the km is killer in the woods, and that is all i have to compare the airborne to.

    I've ridden a 22" geared KM, but it was rigid. Conversely, the KM owner rode my geared/Thudbusted B-29. I thought the monkey handled the 1 or 2 switchbacks (so tight you almost have to walk) only marginally easier. I'll take the B-29 everywhere else. I found the KM to be unnerving on descents.

    The KM owner thought the B-29 was "screaming fast".

    Oh, my B-29 also has a 71.5 HTA which isn't stock I don't think. I liked the slackness enough to get a 71 on the Titus.

    Never ran any tire other than a Nano in the rear, ran the Bonti in the front in one of those older Manitous that just barely work that I had on loan. Never noticed any undue flex either nor sluggish behaviour in tight terrain. I just got rid of it because of the seatpost issue and my buddy that has it now is very happy with the fit and the ride, oh yeah and the wheels, again.

    I've been riding a B-29 since May.

    here is a post I did shortly after I got the bike:

    http://forums.mtbr.com/showthread.php?t=28224

    I think the bike handles great. It is really the only bike I've ridden that can take the place of my steel HT 26" Breezer. It is plenty stiff for me but I'm 165lbs. I have hauled a loaded BOB trailer with the bike and that has caused some lateral flex but nothing really bad. I ride the 18 inch, I have a 32inch inseam and run my saddle at 29inches (measured from the center of the BB to the top of the saddle along the angle of the seat tube) Using the Airborne post this gives me some nice flex and makes for a very comfortable ride. I see no need for a suspension seatpost on this bike.

    The bike floats over rocks very nicely. I run a short travel fork CX-1 at 72mm or sometimes a rigid KM fork. Although having recently ridden a BW .8 for the first time that is my new fork of choice. In general the bike is comfortable and solid. It turns when you want it too and is stable when you need it to be.

    As Bigwheel pointed out the bike was designed with input from Mike C. and Pat I. That is worth a lot. I don't know if there is anyother off the shelf 29er that has this sort of thought behind it.

    Got a 20", 6'4", 36" inseam, 190-200# depending...

    Mine is a stock 20" frame, it's 4.2# and I haven't had excessive flex or rub with the Kenda Klaw rear tire. It seems more flexible than my steel 29" bike but just a little different, not "better" or "worse". I think it handles great! My only "problem" is that the seat tube angle is just a little steep and I can't get back to quite my favorite position with the airborne post and the wtb rocket v saddle. But that's probably fixable with a different post or seat. Anyway, tight singletrack has not been a problem on this bike at all and it's stiff enough for me. Don't forget the two biggest (in my mind) benefits of Ti...other people think it is cool and it doesn't rust.

    On the other hand, if you want to spend a lot less and get a bike that weighs the same and is custom built for you, you could always get a steel custom.

    I am 5' 9.5", about 200 lbs, 31" inseam, and ride an 18" B-29 with the airborne layback seatpost and a 105mm stem. I think it is plenty stiff at the BB and rear end, and love the way it handles through the tight wooded stuff.

    Wow!

    got the frame, buit it up, and i am really diggin' the airborne. quality seems to be up there with all the major players, and this thing rides really nice. funny how things seem weird on paper, but work out ok in real life. i was feeling slightly skeptical about well it would fit and how well it would work in the rocky slow speed stuff, but man, the B-29 is a great ride. after getting the seat where i wanted it, the bike could do no wrong. i am stoked!
