Ritchey Pro stem design change?(4 posts)

Ritchey Pro stem design change?Woof the dog

Did Ritchey change their Pro stem design from two-bolt faceplate to four-bolt faceplate, like WCS, this past year?

screaming bloody murder

Woof the dog.

Yes they did, but if you use the shim for a 1" steerer it weighs almost exactly the same as the old 1" one sans shim, regardless of what the claimed weight is. I don't really see any advantage to the new one other that it has joined the current 4 bolt fad.
It covers more area when bolted and...Paul

is suppose to grip the bar better then the two-bolt design. I have both the 4 and 2 bolt design, and don't notice any difference. Have to be careful when tightening the 4 bolt, as you can easily strip the bolt. With the off-set stem bolt design on the new pro, suppose to be better for carbon steerers.
Yeah, but it's a good change.jw25

The 4-bolt faceplate should hold the bars without needing to torque each bolt as tightly, and the larger bar clamp spreads those clamping forces over a larger area.
The rear clamp's the biggest change, though. Ritchey went to an opposed-bolt system, trickle-down from the WCS, which is supposed to be easier on carbon steerer tubes.
One caveat, though - if you run this stem with a carbon bar, be sure to use something like Easton's friction paper, as the front faceplate has small ribbing sections for better grip. They tend to leave indentations in carbon bars, which might lead to stress risers and failure, which would hurt. Shouldn't be a problem with an aluminum bar, but on my MTB, an Easton EC-70 was pretty chewed up under proper torque.
