Hi fellows, On a tri-bike what would be the best Shimano Ultegra groupos to use?
I notice that Shimano has both the 11-30T and the 12-28T.

Gearing choice is dependent on: type of riding (hills, flat, wind), cadence and power to weight ratio.
So, a strong shinny guy (5 w/kg) on a flat course at low cadence will be happy with 53/39 + 11-23.
and a heavier guy (3 w/kg) who want a high cadence on a hilly course will struggle with 50/34 + 11-32
