stem for 1" carbon steerer?brevard

special stem required? Look hsc2 fork, instructions ask for 1cm squared stem surface??? I've read that an opposite tightening bolt pattern works well, only found 2, ritchey wcs, but uses shim for 1 inch or $200 deda mag??? Ad for cinelli devo, but who would have those already???

I've got a Look HSC2 fork and use a TTT Forgie stem. It has a sleeve (shim) allowing it to be used with either 1'' or 1.125''. There must be at least a dozen high end stems that fit a 1'' steerer. The Forgie I have is very stiff. The Ritchey WCS is a nice stem as well. I wouldn't pay $200 for a Deda.

A Ritchey WCS works fine on my HCS2.

The high end stems come with a sleeve to use with a 1" steerer. I've got the Easton EC 90 stem on the Ouzo Pro 1", 3 cm of carbon spacers, no problems at all.

There are only a few models that use a single bolt to push an internal wedge device into the steering tube, which should not be used.

The rest all use one or two external clamping bolts that are OK for carbon steering tubes. The shimmed models are also OK.

Be sure to install the internal expanding plug to support the steering tube. Some Pro mechanics also recommend cutting the steering tube 2mm longer than the top of the stem and placing a 3mm spacer just below the top cap. Supposedly this reduces the chances of cracking the steering tube. The smart thing to do is properly torque the steering tube clamp bolts, it doesn't take too much pressure to keep the stem in place.

The Ritchey WCS is a fine choice. I run a 1" steerer with the shim and have zero complaints. The weight is low and the price is reasonable. Some say it's not stiff, but a majority of us say it is - let's just leave it at that.
