    XCL Frame angles with 130mm fork

    I'm really stoked about the new XCL. Looks beefy enough to stand up to tech XC trail
    riding with an occasional drop or two. I'm not worried about the extra frame weight.
    I think its worth it in this case, it'll be flex free and durable. I was wondering about the
    geometry numbers, though. I see on Chumba's site it says 69 and 73 for the HA and SA.
    It didnt say what travel fork this was based on. Does anyone know what the actual
    numbers would be with a 130mm fork ?

    I think those numbers are based on the 06 frame and 130mm fox talas fork. I know people who put a 140mm Fox Talas on that frame and did not change the handling at all. Hope that helps.

    Maybe ChumbaEVO could respond with something more definitive. I'm also wondering
    how the recent frame changes will affect the geometry, will it going to stay same as before...

    The new XCLs are going to have the Rockshox Pike for the fork which is 140mm of travel. The XCL has 4.5 inches of actual travel. A lot of bikes that have 5 inches of travel only have about 3.5 inches of actual travel. The XCL rides like a 5 and 1/2 inch travel bike, so the new FOX TALAS or Rockshox Pike is a great choice.

    Well, if its the same geometry as the Motolite, that wouldn't work for me.
    I tried the ML, and on a very steep granny ring climb, I felt a little bit of lower
    back strain. The fork was a 130 and I had the seat height correct and the frame
    was a large, so I'm attributing that to the rather slack (71.75) SA at 130mm,
    which pushed me too far toward the rear for an ergonomic climbing position.

    Yes, Duke777 is correct, its based off of the older Fox forks at 130mm. But yea, I'll measure the head angle with the new 140mm Fox forks and see what it is. I've spent good time on both set ups, and the handling is dialed on both set ups. As for travel, 07 XCLs have 5 inches of rear wheel travel.

    Cool, I'm looking forward to April. Looks to be one sweet ride.

    Measured the head angle with the 140 mm Fox fork, and it is still hovering right around 69.

    10mm increase in fork Axle-Crown should equal approximately a .5 degree slackening in the seat-tube and head angles. And, raise the bottom bracket by .16 inches.

    The 07 Talas should be the same AC height as the previous models, just with more travel.

    I have a sneaking suspicion that the XCL will be reviewed in MBA very soon.

    But only because they were using one in that headset instructional pictorial, and I've noticed tha's how it starts.

    Sounds like it needs some Marzocchi stoke up front then, or else MBA might take a shining to it .

    What is the AC height of a Talas?

    I have a Marzocchi fork and would like to compare.

    Thanks!

    EDIT: My current fork is only a 120 mm, and I am worried about having too steep a headtube angle. Axle to Crown length is 499 mm. Cheers.

    ChumbaEVO, could you measure the SA on the new XCLs to see what it is, say with the
    fork at 130 ? I recently saw some pics on the TItus forum of the XCL and Motolite
    side by side, and it looked like the SA was the same or very close on both bikes; the
    Motolites is 71.75 at 130mm for the fork. I know its hard to tell exactly from a picture,
    but I was wondering if your measurement was maybe a tad off.
