If you asked knowledgeable cyclists what the very best aluminum compact, 110bcd, crank set ever made was, I'll bet the majority would say it's the TA Zephyr. The Sugino Alpina, or Cospea in Japan, would probably be a close second. Unfortunately the Zephyr was discontinued several years ago, but various versions of the Sugino are still in production.
Since there are several versions of the Alpina cranks we asked Sugino to make the best possible model for us. Of course, we wanted cold forged polished silver arms. Sugino also makes numerous grades of chainrings and we speced the finest available, CNC cut chainrings with all the shifting aids for 9-10 speed chains (though they work perfectly with 5-8 speed as well). Then we asked Sugino to polish the rings!
The result is this lovely VO-spec Alpina. 48/34t rings, $165; 110mm BB; Q-factor is around 160mm, about 665gm.
We also received some Sugino chain ring guards, the sort that fit on the crank. They cover 44-46t rings on a 110bcd crank. They will work with any derailleur that has a fairly flat outer cage, like the FSA we stock. On some cranks you may need to file a bit off the little pin that prevents the chain from dropping between the arm and the outer ring, on other cranks you can simply unscrew the pin. $20.
