wapad Posted May 10, 2023 Share I'm looking at getting a Trek Top Fuel, I think I'm at the edge of Large with a saddle height set to 77cm, is there any benefit in getting a larger bike where you are considered more in the sweet spot, most try get a smaller bike because its lighter. at 185cm-6'1" i think I fit on a large any thoughts on the LargerXL frame I'm assuming more comfort due to higher stack height etc. Link to comment Share on other sites More sharing options...
splat Posted May 10, 2023 Share Your leg vs torso length could play a role in that decision. Tall seatpost, longer stem and a stack of spacers on a large could give you a similar position to an XL. Or you could be super flexible and have a massive saddle to bar drop. The weight difference between the two wouldn't really be that much, but the geometry may be a factor. Smaller bike would probably have a shorter wheelbase and lower stand over, so might feel more nimble. Bigger bike would feel more stable. If you are buying from a dealer, they are usually equipped to do a good bike set-up and help you with that decision OVERDRIVE and openmind 2 Link to comment Share on other sites More sharing options...
RobertWhitehead Posted May 10, 2023 Share At 1.85 I will go with an XL and shorten the stem with wider bars. I've been riding Trek since 2011 😁 Link to comment Share on other sites More sharing options...
JuliBoB Posted May 10, 2023 Share @ 1.85m go for XL. I am 1.79, with longer leg length and literrally on the borderline with my Fuel EX 2022 model size Large. So go for the XL and not the L. OVERDRIVE 1 Link to comment Share on other sites More sharing options...
ians H2Sport Posted May 10, 2023 Share I have just been through the same thing, Trek too. I am 186 cm so on the top end of a large (Supercaliber). Ended up going with the XL, only one ride so far but it seems like the correct decision. justinafrika 1 Link to comment Share on other sites More sharing options...
Chadvdw67 Posted May 10, 2023 Share I am 183cm and when I had a Top Fuel I went for a Large, fit me like a glove Link to comment Share on other sites More sharing options...
wapad Posted May 10, 2023 Share Thanks for the input all good points ... so sounds like an XL would be the one. OVERDRIVE 1 Link to comment Share on other sites More sharing options...
Rudi Pollard Posted May 10, 2023 Share I'm 186cm with a saddle height of 79,5cm. I bought a Large Trek Top-Fuel frame second hand and I've always been fitted right on the cut line between a Large and X Large on various brands. I've had to fit quite a long seatpost and had to make some adjustments with the cockpit but got a good comfy fit on the bike. I think I would have been able to get a similar position on the XL. I think you'll be able to make either work for you is what I am trying to say, but try to get the shop to fit you and advise. Link to comment Share on other sites More sharing options...

EDIT - some of thee most expensive school fees I paid in this sport .... and not some weekend casual, nope the owner of the store worked me over like that .....

Frosty Posted May 10, 2023 Share How much are you spending on the bike? For a fraction of the cost, a bike fit will give your the starting point to decide on frame size. Tell the fitter you want to buy a new bike and let them measure you up before you buy. Based on your measurements, you can then calculate your optimal setup once you have the bike, instead of having to buy extra components afterwards. Some examples were given above, like stem length and bar width. Stack height, seat post length, type of saddle and more will make a big difference if you are primed for comfort. Unless you’re racing for a living, comfort and power should be the preferred two corners of the power-aero-comfort triangle. splat and ChrisF 1 1 Link to comment Share on other sites More sharing options...
wapad Posted May 10, 2023 Share The Bike fit things sounds like great idea, I've had a few but in my experience the fit becomes a bit subjective from the saddle to the bars, they all mostly get the pedal stroke right, but i'm yet to meet someone that can say ... with your measurements you should buy such and such frame size in said brand. Listening to the points its probably gonna be an XL, I dont want to much drop and I dont want to prop the bars up with spacers Thanks for the pointers splat 1 Link to comment Share on other sites More sharing options...
thebob Posted May 10, 2023 Share Just bear in mind the new Top Fuels are long bikes. Both in reach and effective top tube length. Try and ride both sizes before you buy Link to comment Share on other sites More sharing options...
MORNE Posted May 10, 2023 Share If you already own a bike you like and it fits well, take this measurement and then go do the same with the new bike. All my bikes are within a few mm using this method. (Centre BB to the imaginary line between your grips) you’ll know instantly if a bike is too big this way. https://www.leelikesbikes.com/rad-bike-setup.html Edited May 10, 2023 by MORNE ChrisF and dasilvarsa 2 Link to comment Share on other sites More sharing options...
wisecrack Posted May 10, 2023 Share I have a height of 1,86m/6,2 feet. Trust me an XL will be a better fit if you have a long inseam. I bought a cannondale and although it's not a Trek with a 60mm stem and 760mm wide bars its an incredible comfortable ride. Your saddle to handlebar drop will be less and that alone is reason enough. justinafrika and dasilvarsa 2 Link to comment Share on other sites More sharing options...
