    fuel ex 29 sizing

    I ride a superfly 100 17.5 now and it fits perfect. Im 5'9" with a 35' inseam. Not sure if I would need a 18.5 or 17.5 fuel ex 29. as the superfly 100 and fuel ex 29 are sized differently. The wheelbase and toptube on the 17.5 on the fuel seem to match up the best to my superfly. but the seattube is only 16.5, not sure if i would have a "flag pole" seatpost.

    I would ride both and see, I am 6ft 1 and I rode a 19 superfly, I now ride a 19.5 fuel but I put a 100mm stem on it and now its great. I am sure you would be good with either size, given that you have a tall inseam I think the 18.5 might make more sense.

    I made mistake on inseam.its 33.5. I went with a 9.8 17.5. The wheelbase and toptube match my superfly the best. I dont like a long feeling bike.

    5'9" 34" inseam, I went with 18.5 fuel ex8. I spent 2hrs riding 17.5 and 18.5. Found the smaller size too OTB feeling and I've been happy with choice. Trek gives 30 days to change sizes.
