    Gunnar geometry

    How's this Gunnar 29er geometry look?

    Size: 19
    Theoretical TT (mm) 615 (24.2")
    Head Angle 71
    Seat Angle 73.5
    Rake 43
    Trail 0
    Head Tube Length 93 (3.7")
    Chainstay Length 450 (17.7")

    Wily is also on the my short list. I'm looking at a geared bike (anti-gear guys, I already have a 29er SS). I've read some pros and cons regarding Gunner. The Rockhound is going for $750.

    Wily, Waltworks, and Gunnar were on my short list. If you order before the end of January you can get this color...

    I take it that none of them made your final cut. I see your Lenz postings. I'm looking to add a hardtail geared to the stable. I have enough parts lying around to build so why not.

    There's also a nice charcoal silver until end of Feb.. I've read that "paint specials" are actually a better paint job, aside from color, than the standard.

    TT will feel longer.

    The steep seat angle will mean that the toptube will feel somewhere around 1/2" longer than on a 73 degree seat tube bike (front center is longer, for all y'all geometry geeks). So you'll need a 10mm shorter stem than you would on a bike with a 73 degree seat tube. Also, I'm assuming that the "Trail 0" figure is a misprint... it'd be a pretty terrifying bike to ride if not!

    That'll be a VERY stable bike. Long wheelbase (~24.5" toptube after correcting for the steep seat angle, and relatively long 450mm stays) and a pretty slack head angle. You'll be able to cruise through rock gardens and such with aplomb. Not the best bike for east coast dudes, probably, or for folks that ride a lot of tight n' twistys. Sounds like a good deal, too. You might want to find out what the BB drop is as well.

    Gunnar BB Drop

    The BB drop is the only thing I have heard complaints about with the gunnar. It has only actually been one complaint from the one person I know that owns one, so take that for what it is worth. Apparently he continually had problems with roots and rocks. If you only ride the smooth stuff, maybe it wouldn't be an issue.

    - You've got me thinking that this geometry might not be what I'm after. I am an east coaster. I save the rock gardens for the Asylum. Here's the intended terrain: fairly smooth, tighter, sand to hardpack, log hopping type single track, throw in some fireroads with speed. I need to be able to pop and hop this bike. Thoughts?

    If it matters, I planned on putting a WB CX-1 that I have lying around (only have 6.5" of steerer left on it tough!).

    The Gunnar at $750 w/ some nice paint sounded like a steel but if it the shoe doesn't fit...

    I suppose it's time I drop you an email.

    I bet it rides a lot like a Fisher.

    Steel will be a little comfier, but it looks like the geo is really close to a L Fisher, with a bit slacker head tube. I couldn't say if you'd fit well or not, that's your gig - but I build most of my East Coast bikes with 72ish head tubes - especially if you're going to use a 38mm offset fork like the WB.

    Without knowing a little bit more about the bike, it's impossible to be absolutely sure, but I get a trail figure around 87mm (368mm wheel radius w/2.1 tire, 71 HTA, 38mm rake). That's a lot of trail. Combined with the relatively long wheelbase (I ride a wheelbase a tiny bit longer than even that, but the trails around here aren't very twisty) it's going to be a bike that's much better for fireroads and straight/rough stuff than hopping little logs and ducking through gaps between trees. My bike is set up to ride like an absolute boat for the stuff around here, and the trail on it is "only" 77mm. 87 is DH bike territory, in my opinion.
