2019 Cannondale Topstone 105 SE front view
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!

About the author

Matt is one of the founding Molefathers of the Muddymoles, and is the designer and main administrator of the website.

Having ridden a 2007 Orange Five for many years then a 2016 YT Industries Jeffsy 29er, he now rocks a Bird Aether 9 and a Pace RC-627.

An early On-One Inbred still lurks in the back of the stable as a reminder of how things have moved on. You can even find him on road bikes - currently a 2019 Cannondale Topstone 105 SE, a much-used 2011 Specialized Secteur and very niche belt drive Trek District 1.

If you've ever wondered how we got into mountain biking and how the MuddyMoles started, well wonder no more.
