    2014 Trek Fuel 29 Size Question

    I am pretty much 5'11" and 155 pounds, and my inseam is between 30" and 31". I currently ride a 17.5" Cobia, and it feels fine, but I saw the new fuels come in one inch increments, and I noticed a virtual size. Does anyone have any suggestions?

    Most of the time I have ridden mediums in other manufacturers, but I have also ridden larges that didn't feel terrible.

    With the one inch increment frames sizes, I was questioning a 17.5 or an 18.5.

    I'm 5'10" and 32" inseam.

    I always felt cramped on a 17.5" (knees felt too close to the bars) G2 bike but rode the new 18.5" bikes last week and they felt spot on for me. It was the fit I could never previously get with a G2 bike.

    Best advice I can give though is test ride before you buy.

    Oh, and the Fuel EX29'er is flipping awesome to ride !!

    I a 5' 10'' and the bike shop recommended a 17.5in frame for the Trek Fuel Ex 8 29er went for, the mechanic at the shop who is a good bit taller than me has an 18.5 so thought a 17.5in would be fine for me. I've since received the bike and it seems good to me in that it's comfortable to ride, the frame looks quite small but I think that's just the design as the top tube slopes quite a bit - the seat doesn't go down much (looks like it should go down further) so I think the bike shop were correct.

    I am 6'1" and ride a L (19.5") Fuel EX. I always felt a tiny bit cramped on my 19" Superfly 100, but the 19.5" Fuel EX is a bit longer in the TT and I think fits me right and allows for a short stem without getting too cramped. They are definitely long TT bikes, but that works well if you like to set them up with short stems. It is nice Trek has added an "ML" size in 18.5" and I think that makes the range really good in finding the right fit. I would think that at your dimensions an 18.5" would be the right size as you seem to have a long torso, as long as you like a little bit longer TT.

    I am 6ft 1in and I ride a 19.5 Fuel but I did put a 100mm stem on it. I would say an 18.5 would work for you.

    Thanks for the Replies, I have been demoing a 18.5, and I think it fits. Funny thing is, my dad is slightly taller ( an inch) mostly in the legs, and he thinks it perfect. I know I wouldn't want any bigger, but I can't imagine being any happier with a 17.5.

    Thanks again,

    Compare the frame reach and stack to your current bike, and keep in mind the the Fuel is intended to be run with a shorter stem than your Cobia. The 18.5 is probably right, but I would check the numbers also.

    I'm 6'2" and I thought the 20.5 inch bike was fine. Some people like I'm small though. I wonder how many 23s they sell.

    I'm 5'11" and ride a 19.5 with an 80mm stem and love it. I demo'd an 18.5 and it felt small to me

    Where is there 20.5 sizing or did you mean 21.5?

    6 ft 33 inseam. rode the 18.5 felt really good. rode the 19.5 felt even better!.

    for what is worth the 26" EX 9 I owned was 19.5.

    so probably 18.5 would be a good fit. test ride 17.5 through 19.5 see what you like best
