    15 or 17 inch Jamis Dakar XCT 650 Comp

    Iím trying to decide between two Dakar XCT 650 Comp mountain bikes. One is a 15 inch; the other is a 17 inch. Both have the same 90mm stem and crank brothers off center seat post.

    I felt somewhat cramped on the 15 inch and had to move the saddle back to the max point on the saddle rails. I also had to extend the seat post to about 1/8 inch from the minimum insertion line on the seat post. The stand over clearance was about 1.5 inches.

    I didnít feel cramped on the 17 inch. The saddle placement was in the middle of the seat rails and the seat post extension was 3 inches from the minimum insertion line on the seat post. The stand over clearance was at most Ĺ inch but not such that I was forced on my toes to clear the top tube.

    Im leaning towards the 17 inch and would be interested in any thoughts before I buy.

    Thanks for your time.

    You don't mention your height, but I find Jamis runs a bit small. I have had many versions of the Dakar XC and currently have an 11 XCT Carbon and a few older Dakar XLT's all in size 19. I am 5'11.5 and the XLT feels a smidge cramped and the XCT is ok. By Comparison, I have a large sz 20" KHS XCT and it fits me like a glove. I find stand-over not that important these days in a 5" trailbike, but that's just an opinion.

    rydr, I'm 5'7" with about a 29" inseam and ride a 15 inch Dragon 650B. I agree with Aresab that Jamis top tubes tend to run on the short side, and moving up to a 90mm stem (from the stock 80mm) has made the fit perfect for me. I use a Race Face Turbine seatpost cut down to 350mm and still have 4 1/2 inches of post in the frame. The Turbine has 10mm of setback and my saddle is clamped towards the back of the rails.

    A 17" frame would have resulted in the cockpit being all off with the bars way too high in relation to the seat, and no standover clearance.
