Cruzbike S40 Gen 6 Recumbent Bike Tech Specs and Fit
Frame
Front Triangle
This patented drive system not only frees us from the long, inefficient chains and special parts fixed-boom recumbent bikes require, it links the upper and lower body across the drive train as it rotates around the axis of the head tube. This linkage allows Cruzbike recumbent bike riders to increase power when climbing or sprinting by engaging the upper body in much the same way professional cyclists do when they climb or sprint on traditional road bikes.

S40 Gen 6 Complete Components
Gen 6 sees the return of SRAM. The SRAM components we have chosen deliver excellent performance and are our favorite S40 build yet. We also upgraded to full compressionless cable housing for both the front and rear brakes. Some components - the Cane Creek Viscoset, KMC chain, our proven reliable hubs - are proven to last and return once again to grace this beautiful frame.
Headset | Cane Creek ViscoSet® Headset (This premium headset leverages viscous damping to make learning easier and improve handling) |

Chain | KMC X11-1 EPT Anti-Rust 1/2"x11/128" EPT |

Wheels and Tires | 32 spoke 3 cross black aluminum rims, aero profile, tubeless compatible, 25 mm wide rim, approx 28 mm depth non-machined sidewalls, Maxxis Re-Fuse 700x32c tires |
Thru-Axles | The latest in high-end cycling axles attach the wheels more securely, are stiffer and flex less than their quick release predecessors, resulting in better power transfer and more resilience. For the new thru-axle on the S40 we chose a sleek, leverless style that even houses its own internal removal tool for the axle itself and brake rotors. |

SRAM Partial Component Package
Ships next business day
Limited Quantities. Final sale. Warehouse Clearance sale items cannot be returned.
We are pleased to offer a partial component packagefor our Cruzbike S40 or V20c framesets . These are SRAM brand components that are currently hard to find at many shops. You will need to add a few remaining parts (see the list below) but this kit will get you far along in building one sweet Cruzbike and will make the process faster and easier because you won't have to wait for components!
Plus, you can't beat the pricing of this SRAM gear.
The SRAM Partial Component Package includes:
- Cassette: SRAM PG-1170 11-32 (11 Speed)
- Crankset: SRAM Rival 50/34T rings and 170mm arms, 24mm spindle
- Shifters/Levers: Sram Rival 22 Road
- Front Derailleur: SRAM Rival 22 Yaw (with chain keeper)
- Rear Derailleur: SRAM Rival 22 - 11 speed
The remaining parts you would need to complete a build would be:
- Wheelset/Tires of your choice - through axle frames are 142mm and 100mm spacing with 12mm axles. Note that the frame sets come with the axles already.
- Compatible Bottom Bracket - the S40 requires a 68mm external bearing English threaded style. The V20c uses an internal bearing English threaded T47 style. You should be able to find a compatible BB for the cranks relatively easily.
-
Pair of compatible disc brake calipers - if you are building up an S40, you will need some road lever compatible disc brake calipers. The front AND rear uses the same type of 140/160 adapter (See Images below).
The V20c would need road compatible calipers, with a 140/160 adapter for the rear. The front caliper for the V20c is a direct mount to the fork (see images below), though some types might require an adapter depending on the brand.
- Pair of 160mm brake rotors that will work with your hubs.
- Chain - Usually the S40 and V20C in stock form use about 3-6 links more than a typical stock chain, so you would want to pick up two chains and have access to a chain breaker tool.
- Cable housing and brake cables - length may vary depending on your setup, but for the rear brake I recommend a tandem length cable to ensure that it reaches no matter your height.
With these SRAM components as the heart of your build you will ensure a great base build for your frameset. As always, we are here to answer your questions as well.
