Cannondale Topstone 105 SE 2019 specification
Continuing my latest trend for documenting the original specification of my bikes, here’s the lowdown on my 2019 Cannondale Topstone.
I finally got my Cannondale Topstone 105 in April 2019 and before things move on too much I thought I’d record where I started from. It’s surprising how useful I’ve found it to be make a note of the details of my bikes, nice to have it all in one place and be able to refer to the geometry in later years!
