I went with an XL in the end after a lot of different answers from decathlon staff, the majority recommended XL. I find it a good size for me, its a real nice bike.
The T 540 has a straight frame ( not the compact curved top tube design of the Ultra range) I think that the size L T540 would probably be a better fit for you, from what you say about your size and proportions.
I have a large and I'm 5'9" with short legs.
Hi Liam_D, which size did you choose? I'm the same height - 186 cm and my inseam length is 90 cm.
BTW, are you satisfied with the bike?
Thanks.
If it was me I'd go with the smaller of the two. As well as what's already been said it will be slightly lighter and a bit easier to get on and off.
Agree with the above. You can't make a 'too big' frame smaller, but you can push the seat back and add a longer stem on a smaller bike. And that looks way more pro than a seat forward and short stem![3](https://cdn.road.cc/sites/all/modules/contrib/smiley/packs/smilies/3.gif)
According to the decathlon size guide you come between L and XL, I would go with the smaller frame since it could be easily adjusted with longer stem. For me decathlon's size guide worked well.
