Bike Sizing (Geometry)
Hi All,
I recently had a bike Boardman MTX 8.8 (2019) size L with the following characteristics seat post length is 54cm, top tube 61.5cm reach 42.6cm, stack 65.1cm. which fits perfectly for me.
So now I'm looking to get the the same model but new 2021 version in the same L size.
I have compared the geometry and looks the the new version size L has a different geometry
Reach is 43.5 and top tube (effective) is 63.5, and their M size is seat tube 49, stack 62.5, reach 41.9, top tube 61.
So the question is will I notice a difference if I go for size L? Or shell I go for M which has quite close geometry to the L size I currently had. Shell I go for slightly bigger geometry or smaller?
Thanks

Pretty obvious that the frame geometry has been radically changed. The only way to tell is to ride both sizes. My guess (and it is only a guess) is that the medium size would feel more familiar than the large
