i know these bikes have been discussed in other threads, which i have read, i would like to elicit some additional comments. i am looking at these 2 bikes (steamroller as supplied by surley complete) and have ridden the fillmore. the fillmore will accomodate a 700X28 tire and comes with a 25. the surley will take up to a 38. i will ride mainly for commuting around boston. i wonder if the flexibility of the surley is a big advantage? size for size the TT length, ST length, and HT length are longer on the surley, particulary the HTL. i guess this gives the fillmore a more race feel. i found i need quite a bit of seat height on the fillmore 57 (i am 6'2") as the 61 is quite a bit bigger, probably too big. thanks for anyones opinion and advice on these bikes.
