    Usefulness of dropouts on a non-single speed

    Iím new to biking, new to my Surly Pugsley. I have a 2x10 setup at the moment and would like to convert to a 1x10 in order to fit a larger set of tires (4.70). From my reading the wider tires will render the inside chainring unusable because of chainrub on the drive side of the tire. This got me thinking about the dropouts. If the tire is too large and hits the seat post can I pullback the wheel in the dropout? Or is it just there for singlespeed adjustment.

    The dropouts are useful for single speed adjustment and also wheelbase adjustment. Wheel all the way forward, quick and snappy ride. All the way back more stable ride especially in loose conditions like snow and sand.

    Awesome. So how do I got about increasing the wheelbase properly for a non-single speed like in my case?

    I'm assuming this is not the new orange Pugs with the revamped geo to fit the fattier tires. I'm not sure of the max width you can get in the back with a 1x10, but I'm sure you aren't going to fit the widest of the Surly tires. The front will clear a 5" tire while the rear is about 4" and a bit more. The Moonlander was the offset rear fatty to fit the biggest tires, the original Pugs is probably 3.8-4.2ish in the rear, the new revamped pugs will clear larger. You may be able to fit somewhat larger tires with some modification to the drivetrain, but you are limited both by the stay widths and the 135 with a 17.5mm (equal to 170mm centered) offset rear.

    Oh, as for increasing the wheelbase... loosen the QR, pull back the wheel in the dropouts, and secure the QR. You may want a tuggnut if the wheel slips under pedaling load and tightening the QR doesn't help.
    I don't know why,... it's just MUSS easier to pedal than the other ones.

    After sliding the wheel back, be sure to slide the brake caliper back also.
