11-Speed crankset dispatched - do'h!

Last night I was browsing the internet to find the FSA K-Force light priced at £179.99 from £640. Anyway, it was £200 for the 10-speed double BB30 but they only had 172.5mm crank arm available. I am 6'1.5 and require 175mm at the very least. I don't know whether dropping by 2.5mm would have made a difference, but I didn't want to chance it after reading debates about how many cyclists are able to detect the differences in crank arm length.

I'm running a 10-speed chain, cassette, and hub but am now going to be taking delivery of an 11-speed crankset which initially after reading the description, I believed was 10-speed compatible.

I've noticed one difference in the description between the two speeds however. The 10-speed state their BCB (presumably BCD) is 130mm whereas the 11-speed description states theirs as 110mm.

What will actually be the difference between the two? And will the 11-speed crankset be compatible with my chain and cassette?

Thanks

    110BCD = compact chainset (50/34 and the like) whilst 130 = standard rings (53/39 and the like)

    BCD only matters if you are wanting to replace rings on the chainset.

    Your existing 10 speed chain and cassette will be fine, the only slight issue may be if the 11 speed does really have different teeth/pick up ramps as the techno bable folk in marketing seem to suggest they do.

    Even if they do it will probably still work.

    640 pounds for an alloy/carbon chain set? They must be taking the piss... no wonder they have to reduce them by 70% to flog them...
    Not even the Super Record in Titanium-Carbon costs that much

    Some accountant at FSA must have got the pricing wrong... it was meant to be 240... :mrgreen:

    You'e unlikely to notice the difference - chainrings are only slightly narrower. Anyone who paid RRP was mugged!
    Make mine an Italian, with Campagnolo on the side..

    Yep, even in my hands I could tell the kit was barely worth anything more than £250 tops. The carbon crankarms are very nice however, but again this doesn't make it £650 worth!

    I wanted a new crankset but didn't want Shimano Dura-ace (too metallic) or SRAM Red Black (because I have shimano groupo) so FSA it was. The spacing between chainrings is fine and luckily saved myself £20 from purchasing the 10-speed chainset.

    How's the shifting on the front mech? The spacing between the chainrings may be slightly smaller and give shifting issues. Having an 11spd crank means the chain would be slimmer. This enables the chainrings (and the crankset as a whole) to be closer together making the crankset slimmer and reducing Q-Factor. If it's all good then congrats!
