1x Mech to 1x Elec

Mitchell Napolitano

2023 was a big year for my gravel bike. I fully overhauled the setup and the bike feels brand new.

In 2019 I bought Clay’s Moots Routt to start getting into Gravel and Cyclocross. Over the past four years I had tinkered with minor changes:

  • Adding a Wolftooth derailleur extender and a bigger cassette / chain for an increased gear range

  • Various cyclocross or gravel tires

  • Handlebar tape

  • Swapping 165mm Ultegra cranks w/ 172.5mm Dura-Ace cranks from one of my other bikes

This year I decided to do a bigger drive chain overhaul and go fully electronic. I have been super happy with the changes to make the Routt to a 1x Mullet setup. Super happy with the result and build out by Acme Bicycles Co.

Ride Thoughts

Pros

  • Smooth riding - the combination of the new electronic gearing, bottom bracket, and freehub has the entire drive chain running smooth

  • Bigger range - the prior gearing left me struggling at each end of the spectrum e.g. gearing wasn’t big enough to go 25+ mph or small enough for more than 8% grade

  • Less cables - the electronic setup means I have a cleaner look w/ only brake line cables

Cons

  • Sensitive gearing - the range is so polarizing that slight adjustments mean I can’t fully shift into all gears. At Farmer’s Daughter this past year rough riding led to a limit screw coming loose and I was unable to shift into my smallest gear ratio halfway into the race

  • Tire clearance - I wasn’t expecting to get increased tire clearance with the changes I made, so this is generally a complaint that the frame still maxes out at 40mm tires

  • Battery removal - the derailleurs battery follows the typical SRAM clip-in, however it has an extra cage around it that is difficult to remove
