  • Hi all,

    I’ve just bought a surly disc trucker frame as a winter project to build up for spring next year. I’m currently a 90s mountain bike guy using my bike largely for commuting but often for bikepacking too. I’m currently on a 3x7 drivetrain and find I never leave my middle cog. I believe it’s about 34t. I very occasionally use the largest and in the past year have used the smallest once.

    This has led me to think I’d be better off with a 1x system. I’ve been thinking of a 1x10 set up with 11-45t in the back. Seeing as I can seemingly do everything with my 34t I’m thinking I’d be best to maybe put something a little larger up front to make use of all the gears. Maybe 36 or 38t?

    I really want the bike to be a bit of a do everything bike. Rideable on all terrains, able to manage decent climbs, good at carrying a bit of weight but still comfortable as a city rider too.

    Can you guys weigh in on what you think of 1x systems for these applications? Would 38x11-45t give me a decent range to have a crack at whatever I throw at it or would something else suit better?

    Hoping to get these ideas set out before I begin the build in full!

    Cheers

  • 38x11-45t

    Your fitness may vary etc. but this is a pretty decent choice. Run 38x11-42 for road, commuting, grav, touring. Fully loaded and off road can be a little challenging but no plans to change.

    My partner runs 36x11-46 and that's really good if you don't want to descend fast.
