Easy one you've got a feel of the brakes and shifting
However, do get someone in the shop to show you how double tap works, front and back...not that it's that difficult Don't want to snap your brake levers off trying to shift with them
HAHA. Thanks, I currently use SRAM RED and I love the double-taps.
I did strongly consider getting a carbon frame (can get the RT-58 frameset with a bunch of stuff thrown in, like bars/tape/etc for £400) and transferring the RED kit over. £800 for the complete bike seems to make that a daft idea.
I also looked at other bikes with taller head tubes. The Giant Defy Advanced is huge (205 for the Large, compared to 170 for the RT-58) but it's £400 more and it's all disk brakes.
The Merida Ride at £839 looks very tempting. May well be a better balance between comfort and performance (190 HT for the Large) - relaxed without catching too much wind. I like SRAM though.

The CAADX headtube is 160. The RT-58 brings that up a little, to 170, and if I get them to leave me with as much height on the stem as they can then I should be good.
