Paddy Wagon for commuting. Truly lovely geometry, takes proper SKS mudguards, needs an M-part seat clamp to take a rack. The wheels are heavy, the freewheel will rust, and it’s built down to a price, but it is so much more than the sum of its parts. I commute 10 miles each way fixed, ride a medium paced chain gang and generally love it. So much so, that I’d like a Burls titanium version of the same (with that lovely steel fork).
Mine has upgraded handbuilt wheels (Open Pro/Miche/ Schwalbe Durano S), a carbon seatpost and Ritchey bars and stem, and ride 48:16. Even with mudguards it’s sub 10 kilos (no rack). With the nice summer track wheels, it’s 9.5.
EDIT: Mine is a 2009 version – that had those yellow wheels. Funny thing is, this years now looks more like mine! And try fitting proper mudguards to a Langster 😕 . It can be done, but there is no chainstay bridge.
