It also weights only twenty grams more than a standard ultegra crank, which isn't a big deal at all.
So, I don't know what that your reasoning for that was, but if you want a compact, the r700 crank is a much better deal.

yeah, and the $95 deal is for the 172.5mm only... so out of all the options of...

Silver or Black
105 standard double 165mm
105 standard double 170mm
105 standard double 172.5mm
105 standard double 175mm

Silver or Black
105 triple 165mm
105 triple 170mm
105 triple 172.5mm
105 triple 175mm

Silver or Black
105 compact 165mm
105 compact 170mm
105 compact 172.5mm
105 compact 175mm

you get to choose between...
jenson offers... 1.
CRC offers... more than 20.

Seeing as cranks are an attachment point, if you don't want 172.5mm in silver, then the jenson $95 deal is no deal, it's just money wasted.
