size for a long inseam with limited resources ..

mosman

Hello everyone, before I get flamed by all the use the search tool and get a custom frame or seek a professional bike fitter.

My resources are limited and where I live I can't get a custom frame nor an avaliable bike fitter is present, I can't even try the bikes.

After some research I came to the conclusion that I want a giant contend sl1 2018. It ticks all my boxes as well as my budget.

But I am confused as I will have to order it and don't have the luxury of trying it first.

My problem is my how my body proportions are. I have a long legs short torso with average normal arms.

Barefoot at 5'7 (170cm) with inseam of 32.1 inch (81.5cm). I am torn between the small and the medium.

Giant's own sizing chart puts you on a small. I'm an inch shorter than you but the same proportions; I'd choose the small too.

If you buy it then feel you need a bit more reach you can try more saddle setback and a longer stem. A few mm can make a lot of difference

I found one in a shop on display in small. It's my first road bike. I don't know if I look cramped or fine. Here a Pic

Looks to small to me. You are on the junction of Small/Medium

I would not take to much notice of the Giant size chart. When I bought my 2013 year model Defy Aluxx SL, Giant recommended a Small for 5' 7 1/2" tall and 32" Inside leg. Fortunately the shop where I bought my bike from had a Small and Medium bike to try for size. I felt to cramped on the small, to much saddle to bar drop, the Medium was much better more stack and reach, only change I have made is to move one of the 10mm stem spacers above the stem.

I would advise you to try and find a shop with a medium bike in stock to at least try it for size.

Note
The Aluxx Contend is not the same as the now discontinued Aluxx Defy. There are subtle differences in the geometries of the two bikes. Main difference being the shorter chain stays. Look at the Stack and Reach figures of the two bikes.

I think I will go with medium, although I feel more stretched but better than cramped

Is the black and green bike a medium frame? If you feel too stretched out you can always swop the stem from the standard 100mm length to a 90mm. You don't say whether this is your first road bike? But I would advise you to try it as it is first, you may find it fine once you get used to road bike, drop handlebar geometry, especially if you have been used to riding a straight handlebar MTB/Hybrid.
