Culprit set out to make the fastest, user friendly triathlon bike. The design goals were to make a bike that was fast, easy to travel with, had lots of hydration options and could use most aftermarket parts.
So, we started with our patented design of no seatstays. We chose to keep the front triangle because of what it offers for hydration needs. Some people still prefer to use standard hydration in training or racing and we know that some long training rides you need to carry as much as you can. So, fitting 2 bottles in the front triangle for all sizing was a determining factor in the rest of the tube sizing.
From there, we wanted to use brake systems that could be purchased easily in the event of damage. Of course, we used a new TRP rim brake integrated into the fork and covers, but when removed, a standard Shimano direct mount brake can be used. Same holds true for aero bars and stems. We worked with a new brand to develop what works seamlessly with the bike but any aftermarket bar and stem will work on this design allowing even further fit refinement for a rider or the ability to transfer over parts and only upgrade a frame.
We realize disc brakes are the future and believe strongly in them ourselves, so we put more focus on the disc fork of the bike first since calipers are already on the market. The disc brake version of the bike out shined our rim version as the air flow of the fork is truly amazing as there is airflow at the top of the wheel/fork that a rim brake blocks. Upon testing the rim brake forks, we had a prototype brake and were awaiting a final brake design before finalizing the fork design. So the rim fork will see some changes before production which will lead to a faster rim version of the bike.
Some of the additional features of the bike include a multi tool in the top tube, interchangeable drop outs for rim or disc, 1x11 cover for running a 1x11 build and hiding the Front derailleur frame recess. Bento box included but any bento box can be used in its place.
We only tested the bike against a Cervelo P5-6. We would have loved to test more bikes but were unable to get bikes with the same fit measurements to run against the Legend. The bike did very well in the tunnel. We did not set out to make the FASTEST bike at all expense. We had design features we wanted to offer athletes, mentioned above and this limited some of what we could accomplish and added a slight drag penalty. But we, Like Quintana roo, Want to offer a user friendly, fast bike and the data supports that.
The Culprit Legend disc establishes itself as a serious contender in the triathlon market. The data confirms that the Legend disc can compete with the best. Testing has shown that the differences between the Legend and P5-6 are very close. The average CDA difference between the two bikes is only .008, or 1.9 aero watts. This is even more astonishing considering the non integration and use of disc brakes.

For those naysayers about Faster wind tunnel. the delta between the two days of testing was zero, or a CDA difference of .120 and .1205 on their Cervelo S5 they do for baseline testing. Image of S5 below
