SRAM RED Cranksets

[LocknLoad]

Hello All,

 

Hoping someone can explain something to me in simple terms. Could be a really stupid question but it is bugging me.

 

Was reading online

http://www.sram.com/sram/road/products/sram-red-crankset

 

What are the primary differences between the GXP and BB30.

 

I see they sell for the same online

Is it really just smaller thinner crankarms? I get the heel clearance but I mean how big do your ankles have to be to be hitting the crankarms?

 

It the BB30 lighter and stiffer than the GXP?

 

Anyone able to shed some light on this?

 

Thanks.
