2 Years Later: The USE Alien Seatpost
Alien Clamp Fitting Instructions. Well its been two years since I installed this. The reviews are right. It is super light (just 140 grams), but incredibly hard to adjust. When I sit my fat butt on the seat, it literally locks into place. When I disassemble pieces go flying.
The most depressing thing is that it uses 2.5mm hex key which isn’t standard on my little Park tool, so if it slips (when it isn’t tight), then it is a real problem on the road. It says it only need 11.5 inch pounds or 1.5 newton meters to tighten. Hmm. Mines needs much more to stay locked in. May be why the hex bolt is now stripped.
In any case, it is great, but just hard to adjust. Next one I try I might give up a few grams for easier adjustment.
