That's not bad! Didn't look long enough when I last looked but that ad has the dimensions. EDIT: Ah, the longer ones are in alternate views in the ad. THANKS! EDIT: Well, these close on each side of the handlebar stem, would completely overlap the clamping area of the clip-on aero bars. So they would need to go outboard, but then just wide enough to clear the aero bars, and they are in the tapered area of the handlebar. Wider and they interfere with left trigger shifter which can't go any further outboard due to the brake levers (the original Microshift combined shifter/levers, the shifter broke, replaced with bombproof Shimano Alivio). So I'd need to replace handlebar with either, one that tapers further outboard, or one that tapers or steps down more inboard, and then use shims to clamp around the 22.2 dia instead of 25.4. Nothing's ever simple.

Oh I agree, that was my point. I just wanted to say that for efficiency, lest someone suggest that as being long enough.

Its the stem, which is very rigid, that is heavy. Tern has the same stem in several height.
Only the double-clamp and not the T-stem, weighs 0.328kg or 0.7 lbs; That's on the heavy side, though understandeable as it is stout (and OEM stout as they have greater liability so I think go more robust), plus the additional weight of the levers. The Physis 3D handlepost, based on length from 250 mm to 350 mm, ranges from 1.5 to 1.7 lbs itself.

I've seen Syntace 60 mm clamps before, but not available here and I think they were $60. I now see 47 mm ones available, as just the clamps, not long enough. They are showing longer ones, with clamps as part of a typical aheadset style stem with a T for the clamps, and that is designed to clamp around a "plain" cylindrical vertical handlepost. My early Dahon post has the handlebar clamp (and C style, not clamshell) welded integral to the handlepost, and below that is tapered to wide at the base, so I can't clamp the VRO to it, unless I get a new plain handlepost, but I'm having a hard time finding one as long/tall as my old steel Dahon post.
