Simplon unveils 30-watts-faster Pride II aerobike and new bike fit system – CyclingTips

Almost a year ago, a UCI rule change on frame design was leaked. At the time, it was hoped this rule change might stimulate a design shake-up, amalgamate the road and time trial bike regulations, allow manufacturers to reduce tube thickness, and increase tube depth, amongst other things. Simplon has now unveiled its new Pride II aero bike, leaning on those relaxed rules to develop a bike Simplon claims is “the fastest road bike in the world”. 

We spotted the new Pride II at the IAA Mobility show in Munich last week. Having given the new bike an eyeball wind tunnel test, it certainly looks fast – hardly surprising given Simplon’s stated goal for the new frame was to “develop the fastest road bike in the world.”

As is the done thing now when developing a new aero product, Simplon partnered with the aerodynamic experts and wheel manufacturers at Swiss Side, to assist with the frame development and CFD analysis. The results of this development partnership are clear to see. The Pride II has a much deeper head tube and fork legs, plus a raised bottom bracket /seat tube / down tube interface area compared to the outgoing Simplon Pride 1.

Simplon didn’t rest there though. The Pride II also benefits from a compensation triangle where the seat tube meets the top tube, and a split stem that rises from the stem clamp, which sits in line with the head tube. Of course there are also the obligatory dropped seatstays and truncated tubing.
