Emails,  in biblical proportions, have been flooding into the Planet Gary post room from far and wide, well, not exactly flooding, just the one from across the pond in Fargo, North Dakota, of all places. The request was for the projected build details of the Surly Pugsley single speed, and how I managed to get the weight down to a projected 13.00 kg. So rather than only replying to the email, what better place than to list them here on Planet Gary.

The weight of the finished Surly Pugsley single speed should end up around 13.00 kg but may change over time as I find alternative components. It might be worth noting that a single speed fat bike might be challenging to say the least. Big fat tyres have considerable rolling resistance, particularly on soft, loose surface such as snow or sand. Beware! More soon.
