This came off a recently purchased new bike and has only been used on a couple of test rides. it is an Ultegra SL Crankset, with 53/39 rings, 172.5mm length and in “ice grey” finish. the Ultegra external bearing BB is also included. Asking $200 obo.
What bike did it come off? Unfortunately I don’t need an Ultegra Crank, I have an extra one too to be honest, but it looks like an FC-6650 instead of FC-6601. The 6650 is the Ultegra SL crank which is actually slightly ‘better’ than the normal Ultegra crank, ‘better’ in this case meaning a little lighter and a little more expensive. The observation is based mostly off of the color, the “ice grey” is the color for the SL group and that happens to be what came on my Felt B12 last year.
The crank & BB came of a Cervelo RS. It was not a factory build as the shop built up the frameset. I took a look at the part no. on it and it has FC-6601 on the drive side and FC-6601/6604/6650 on the non-drive side (the picture is a bit blurry, above).
Ah, it’s only a subtle difference but intent was to point ou that it looks like you have an Ultegra SL crank isntead of a normal Ultegra, therefore hopefully making it a little easier to sell since it is a nicer crank.
