OK, I know you're all hardcore MTBers and probably not interested, but just in case..
Looking to do a 70.3 event next year and hopefully full Ironman the following. Now starting to check out options for a TT bike and getting confused with all the variations in sizing/geometr!
I've seen different manufacturers offering large frames with a huge variation in top tube length (e.g. Planet X vs Giant), ranging from around 530mm up to 570mm. Head tubes, too, seem similar, from 100 up to 150ish.
I'm 6 foot and mostly feel comfy on a 570 (top tube) road bike, 170 or thereabouts head tube.
I realise position is completely different and TT bikes generally need to be shorter and lower.
Be good to hear from anyone who may have both a road and a TT bike. What kind differences in frame measurements do you have? Basically, wondering if there's any kind of +/- rule I can follow as a reasonable guide.
Anyone?
