the difference isn't that high, many would argue sram offers better value for money on the low groupsets particularly. And one of the reasons shimano can be had so cheap is the huge OEM following, it's a catch 22 for Sram and Campagnolo until the cycle is broken
Came here to post that. Regardless what you think of those frames, that's a great deal.
The email says they're going to stop using Shimano on 2015 builds. Campag and SRAM all the way apparently.
Seems a stupid decision given the value that Shimano offers.
