Integrated cockpit measurement - am I missing something??

[slosh415]

My wife got a great deal from a friend on Scott Addict RC. I don't love the integrated cockpit and full internal routing, but that's life. It's still a great bike.

We need to shorten the reach and I'm baffled by the way Scott measures the Syncros Creston IC cockpit. Has anyone else been confused by this?

Apparently it's the 100mm length and they claim a 75mm reach for the bars. I've measured it a bunch of times and I always come up with ~205mm of total length relative to the center of the steerer tube.

Am I missing something here? Is it common to measure these integrated/internal cockpits from a point in front of the center of the steerer tube?

Handlebar reach is measured to the point on the bars where the shifter is mounted, not the furthest forward point of the drops. This is always a little bit of a nebulous measurement since the shifter can be mounted in multiple positions, but it would roughly explain the extra 30 mm.

It looks like all of your measurement points are incorrect.
But since it is 100, and the smallest that they make is an 80- just get that.

I've never seen any handlebar manufacture measure reach to where the shifters are mounted (which as you say, can vary). Everyone I've seen measures reach from the center of the stem clamping area to the center of the bar at its its furthest forward. Where I've seen them vary is the up/down angle of the bar for the reach measurement - reach will measure longer when bars are oriented with the forward bend horizontal.

If you remove the 30mm interval from your drawing, that looks about right.

Interesting, looking at those drawings, it looks like they measure reach at the center of the tube at the furthest point, which roughly corresponds to the part on the top of the tube where the shifter mounts. I had always interpreted it as the latter, but I guess it is what you said. Which is still different than where he measured, which was to the the outermost point of the tube at the outermost point at the bend.

Come to think of it, it also looks like he measured reach from the back of the tom and the front of the lateral part of the bar.

So I suppose all of his measurements could be corrected by just adjusting to measure at the middle and not the edge.

Sorry, my photo markup is not the best and the camera angle might not be ideal. But I definitely did not measure to the outermost point of the drops, I measured as accurately as I could the point that Mark McM showed in manufacturer's drawings, which is how I've always seen bars measured.

Either way, the the total 175mm (starting at the center of the steerer tube) would still fall short of a point on the bars that seems reasonable. I was thinking maybe there's some way that we're supposed to be measuring these fully internal cockpits and/or aero head tubes. I can't think of any reason why that would be the case, but I've seen weird things before from the bike industry.
