    Inbred 26" Geometry?

    looking at this frame for my wife, what's the wheelbase and bottom bracket height of the 14" and 16" frame?

    Thanks!

    Yes, geometry is listed on the UK website. On-One Inbred 26er Slot Dropout

    They do not list wheelbase, BB height or BB drop. The Inbred is sold as a frame only, without a fork. The BB drop and the wheelbase will depend on the fork you pair with the frame. The BB height will depend on the fork and the size of the tires.

    I can tell you that, in general, the BB height on 26" Inbred is pretty high. At least, it feels that way to me. The wheelbase seems on the long side to me, although the HT and ST angle are pretty tight making for nice razor sharp XC-type handling. I'll measure the BB height and wheelbase on my bike and get back with you. If you prefer slacker, more stable, geometry go with the 456 instead of the Inbred.

    hey Boland, thanks for the info.
    See, I am choosing between 456 and Inbred. I have a hardcore XC bike, the GT Zaskar expert and it sucks for decents, i mean its horrible, but it climbs as if it has a motor inside and on smooth singletrack it kills anything. So I want to compromise and make myself a more trail/AM friendly hardtail that is faster and more stable on the DH but not full out DH/AM hardtail. My riding style is, I never take the same route back, even if i am lost i find a new route home and go for 50 km+ rides when i have the time so I ride variable terrain. Is the geometry of the Inbred to close to the Zaskar? HA is 71 for Zaskar and 70 for Ibred with 100 mm fork. while SA is 73 for both frames.
    would the 456 slack HA compromise a lot for long day tours or would it be fine except that it would not be as efficient on uphill? I know a lot of these things are subjective but I am willing to sacrifice a specialist for a good all-rounder.

    ok, long post, hopefully your boss wont catch you at work while trying to finish reading this post :-)

    I thought the Inbred HA is 70 with 80mm, so 69 for a 100mm. I have a 120mm with an Inbred I'd consider it setup for trail duty.

    Just adding bb height for 18inch is 12.5 with 2.25 nobby nics and reba rlt dual air. I don't consider that very high and I think Shiggy posted his BB height on an Inbred swap out with 650b wheels was a hair under 13inch.

    I've never ridden a 456, but from what I've read here and in reviews, my educated guess is that, compared to the Inbred, the 456 works better with the longer travel forks, is faster and more stable on the downhills, but is slower and requires more body English to steer on tight twisty trails. I don't know how it climbs, but its a hardtail, so it must be pretty darn efficient. My guess is it would be a fine all around mountain bike for long days in the saddle. But the Inbred is too (God bless steel frames). Again, the performance of either frame is going to depend in large part on the fork you choose to put on it, so youíre mileage may vary.
    I looked at the Zaskar geo chart on the GT website, but I can't really tell which one is your bike. 26" Zaskar alloy? That bike shows an HT angle of 69.5 degrees. Seems pretty darn close to the Inbred's 70. Chainstays on the 26" Inbred look a little longer, like 6 mm. So, I'd say the geo looks similar - probably imperceptibly similar for an average Joe weekend warrior like myself. There are many variables that effect handling beyond just the frame geometry - trail, COG, stem length, handlebar width, tires, etc - they all work together and you can't boil it down to one or two geometry numbers. Still, Iím pretty sure that, all other things being equal, the 456 is a bigger departure from your Zaskar than the Inbred, if thatís what youíre looking for.

    I measured my 20" Inbred slot dropout w/hanger.
    Wheelbase is 43 3/4, bottom bracket was 12 3/8 unsagged with a 100mm fork.

    Boland, my Zaskar is a 2009 Zaskar expert size L. it has ana HA of 71 degrees and SA of 73. the top tube is 619mm. I am 182 cm, so right between a size M and size L and have a 90mm stem. the riding stance on the Zaskar is very agressive XC. So maybe a 18" inbred would be a drastic change from my zaskar to begin with. Some people told me that the 456 with a 100 mm fork would really drop the bottom bracket and which would make it too low for a more AM style setup. This would not be an issue with the inbred.
