I Wonder why there are no factory or retailer informations about frames length which could be helpful to decide on a purchase (could be critical for a 36er for example).
The only clues we have are the recommended leg lengths which are rather useless because it doesn’t take into account the various crank sizes, thickness of saddles and riding styles (also some riders like having stretched legs and some don’t).
It could be interesting to create a database with measurement from top to middle of the axis, organized by frame size in an updateable table.
So here is a link to a shared table including length, width, weight and material of each frame. Feel free to add a line near the appropriate size and brand (the software itself is in french but you only have to use one of the green crosses to insert a row) :
Multiple entries for a single model are not to be excluded due to eventual discrepencies.
