Coke Can vs. Ceramic Speed – Aero OSPW Face-Off

Ceramic Speed is somewhat concerned by a new entrant into the niche market for aero Over-Sized Pulley Wheels (OSPW) as the €739 price tag for their latest pulley wheel and carbon cover is significantly undercut by a bit of cut-up coke can.

An unnamed, senior exec at Ceramic Speed was quoted as saying, “!£$”£%%, we didn’t see that coming.”

The competing derailleur cover comes from Simon Warren, author of 100 Climbs, who got this novel idea whilst sipping his favourite carbonated beverage at a book signing in his local WH Smith book store. “What if I just cut it and bent it a bit?” he mused. Sure enough, a bit of cutting and bending was all that was needed to fashion what is likely to be 2022’s most novel cycling invention.

Provenance

Ceramic Speed worked with Simon Smart (Drag2Zero) for 2 years of wind tunnel testing but Simon Warren scoffed at the expense and knocked up his caffeine-inspired invention in about 30 minutes in his shed.

Claims

Ceramic Speed claims that “a pro rider [can save] 2.5 seconds during a 25km time trial ridden at a quick 50km/h pace, while a competitive age-group triathlete riding at 30km/h will save 1 minute and 15 seconds over a full-distance IRONMAN.”. Simon Warren claims his invention should save about 1 watt (maybe).

Opinion

The €1 price tag from Warren seems reasonable. I was a little disappointed with his choice of Coke as my TT bike is blue and would better suit a Pepsi can.
