Since more than a few of us tinker with our position on the bike, it might make sense to just trade stems rather than buy stems all the time.

Anyway, I have a 100mm Ritchey road adjustable stem (http://www.ritcheylogic.com/web/Ritchey~Logic/Ritchey~Site/Templates/eproducts_single.aspx?id=16963) (up to 45 degrees) for 1 1/8" steerers and 31.8mm bars. It's about 6 weeks old and in perfect condition.

Also have a 100mm Specialized multi-position stem (http://www.specialized.com/bc/SBCEqProduct.jsp?spid=25337) (20-28 degrees in 2 degree increments); for 1 1/8" steerers, 31.8mm bars.

Looking to trade for a 120-140 stem.

nice idea. i have the following that i've been trying to sell, but would gladly trade for a shorter stem. and by short, i mean really short like 50 or 60 mm. these stems just came with other bikes i had and haven't really had any use for them.

1. Dimension threadless stem
Fits 1 1/8" steerer and 26.0 mm bars
Measures about 100mm long

2. CRP threadless stem
Fits 1" steerer and 26.0 mm bars
Measures about 90 mm long

Also have a Delta stem raiser (http://www.deltacycle.com/product.php?g=9). Black, 1 1/8", threadless, barely used. You can raise the bars up to the max position or any position below that.
