The Legend is Shimano, Sram and Campy compatible. Final parts and build specs are not final as we will release final build pricing in 2017.
The frameset was designed to use most and all aftermarket products. The Seatpost is using a Ritchey clamp design which allows multiple aftermarket rear hydration options. It also allows for multiple rail adaptors to be purchased for personal saddle preferences. The frame uses BB386 standard so that any Shimano crank, Sram GXP, Rotor Crank or FSA 386 crank can be used. The headset uses FSA 1 1/4 lower bearings and 1 1/8th upper bearings. With our custom top cap. However, in the event of necessity, a standard top cap can work on the frame without the fork cover. The Bento box can be replaced with any top tube mounted bento box if ever needed in a time of need. The Steerer tube is standard 1 1/8th so any stem/ aero bar can be used. Braking was designed around Shimano flat mount for disc brakes but any disc caliper, post mount or flat mount will work on the frame/ fork with appropriate adaptors. Rim brakes were designed for use with a new un released TRP model which is center pull, however, the bike can work with shimano direct mount front with the fork cover off and rear under the bb if chosen.
The frame uses Shimano 142x 12 mm e thru for disc brakes or 130 OLD rim brakes. Alloy adaptors are used for both of these options on the same frame. Forks are specific. So please choose the fork of choice, or you can order both upon purchase.
Overall, this is a superbike that was designed to be easy to travel with. Easy for the home mechanic to wrench and service at home. It was also designed to be able to accommodate aftermarket products as we all know things happen in travel and over time. Proprietary parts only make repairs longer and more difficult so we have offered a bike that is easy to repair anywhere in time of need.
Small details such as food/ hydration and storage were taken into consideration as well. The bike can run standard water bottles/cages on the down tube(high or low position) and on the seat tube. As well as many aftermarket BTA and behind the saddle options. We did not want to offer fully integrated hydration as some of our competitors as we realize they do get dirty, damaged, broken and do not want to lock you into our product only. We prefer you have the option of using any aftermarket product you want or can find in a pinch. We also designed the frame to store a multi tool in the frame just in front of the seat clamp. So all the tools needed to adjust your bike are always with you wherever you go. There are mounts for a storage box behind the seatpost for aftermarket products. In time, culprit will develop their own box to pair perfectly with the bike.
Wind Tunnel Testing
During our visit to the Faster Wind Tunnel, we were able to verify that the Culprit Legend is in the superbike category. The Legend was able to compete against the benchmark Cervelo P5-6 and even posted lower drag at some Yaw angles.
To keep the data consistent, we ran the same rim profile for all testing. We used a Black Inc Eight TT (75 mm carbon clincher rim) to build. We built a 20/24 spoke front wheel for rim brakes and a 24/24 spoke disc brake wheelset using shimano centerlock hubs. The bikes were set to the same stack/ reach numbers and used the same 3T extension bar design to get the same fit measurements. We ran the Cervelo in 2 configurations. 1. With an x lab bento box 2. Without the bento box.
We then ran 1. the Culprit Legend as a disc build running 140 mm rotors and shimano flat mount calipers. 2. The Culprit Legend as a rim brake bike with TRP's new front brake and shimano direct mount rear brake. 3. The Culprit Legend as a rim brake build but as 1x11 using Shimano di2 Ultegra.
The White paper will be posted with our Kickstarter launch soon. However, the wind tunnel validated our CFD and performed very well against the Cervelo P5 in all 3 configurations tested: Disc Build, Rim Build and a 1x 11 build. Keep following us for more updates.
The Legend will still undergo a few minor tube shape changes as we were able to verify some changes needed from wind tunnel testing and CFD results. These changes will be reflected in the final version and retested when the bike is in its final carbon form. We also realize that the materials used have some affect on wind tunnel results, so will retest again when the bike is in a final painted, carbon form.
