Lightning Bolt Single Speed Break-Away Frameset

Sale price Price $2,128.00 Regular price Unit price  per 

The Single Speed Lightning Bolt shares the same geometry with the other two Bolts, but opposed to having vertical or thru axle dropouts it has rear facing horizontal dropouts. It also has 120mm rear spacing to accommodate your typical fixed/ flip flop hub. It is still designed around a 650b wheel like the other two, but can be set up 700c with a 35c max tire size. You can set it up with brakes running either wheel size.

The Single Speed Bolt utilizes Ritchey's Break-Away system. It has a split at the seat stay/ seat tube junction and a coupler in the down tube near the seat tube. It requires you to loosen three bolts in total and pull your seat post. This allows you to easily break down the bike for travel or any other reason you'd want to make the bike very compact. The wall thickness of all of the tubing has been bumped up slightly to prevent denting while packed away in transit.

This bike is ideal for those of you who do a lot of traveling, flying or not. It also makes for a super fun Randonneur style bike, commuter, or all-around-do-whatever bike.

Build Notes

  • If you aren't too keen on the fixed/ freewheel single speed life, you could also set this bike up with an internally geared hub. Orrr if you want to keep it real simple and still have a brake you could just throw a coaster brake on the back. The possibilities are numerous.

  • Designed around a 650b Wheel with 48 being the max tire size. You can run 700c wheels with 35 being your max tire size.

  • If you are going to be running a 650b wheelset and want to run brakes you'll need something with at least 75mm of reach for the rear. The Dia Compe Long Reach Centerpulls are a functional and nice looking option.

  • It is belt drive compatible and has a two bolt coupler in the drive side seat stay to sneak a belt through.
