Well, somtimes things go right. I ordered the MAP bar in black with a 31.8 mm clamp, and the only width in this model is 61 cm, instead of the narrower 57 cm. The mtb bar it replaced was cut down to 53 cm, so I thought 61 cm would be far too wide.
It turns out that, at least for a very brief ride (dark and late), the 61 might just be perfect: sure, wide, but it is that wide only at the ends, which curve back considerably more than the cut down mtb did; very nice for a more relaced sit up position, if not quite as upright as in a perfect world. But the grips at the ends are comfortable and I can always bend my elbows.
And the curves, ahead of the levers, will be perfect for flatland cruising. I must tape that section in a color of startling contrast.
Poor night time photos in cluttered garage.
I've loosened and tightened the 4 small clamp bolt of the very lightweight Ritchey cross stem (so marketed) so often not only are the heads rounding out but the aluminum threads in the lower stem side of the clamp are starting to wear away; I won't be able to adjust bar angles very many more times. I saw little silver aluminum bits on the front fender when I was fiddling with the clamp; took all bolts out, liberally greased threads, worked a stout steel bolt in from the back and cleaned things up sufficiently to get the OEM bolts back in from the front.
But until I swap stem and bar for say a Dajia Far Bar and a more upright stem, it looks as if this will do very well.
Had to lengthen brake cables and housing, but easy job with the low-end Tektro mechanical discs. I don't know why people complain about mechanical disks; not superlative, but as good IME, all told, as most rim brakes, comparing strengths and weaknesses.
Hope to get a real ride in tomorrow.
Also: The cut down bar shown is free for postage. It is 21"/53 mm wide measuring across the arc and not along the bar.
Please reply offlist if interested in old bar. You pay postage.
