April's best tech: giant gold jockey wheels, Cav's aero helmet, and more

CeramicSpeed oversized pulley wheel system

This month, the bling king that is Oliver Bridgewood brought along some GIANT jockey wheels. As funny as they look, they do actually serve a purpose.

The gigantic wheels have 17 teeth each and are meant to be able to save at least 2.4 watts over a standard rear mech pulley system – that's roughly 10 seconds over a 25mile TT to you or me, which is pretty impressive. It's all down to chain angle, with the whopper wheels meaning the chain is more efficient on it's journey from chain ring to derailleur.

Met Manta CVDSH helmet

For this month, Paul Norman has nicked Mark Cavendish's helmet. Ok, so not the helmet, but a Met Manta from the CVDSH line nonetheless.

It's an aero race helmet in a size large which, according to Paul, is well ventilated and pretty lightweight.

Selle San Marco saddles

Oodles of on bike comfort is the order of the day from Selle San Marco, and this month we've got two of 'em!

The Concor Supercorsa comes in the beautiful original design from the eighties, when it was first made. That's rhino leather it's made from (probably not real rhinos, though) which makes it dead grippy and super comfortable.

The second is the updated version. It's a Selle San Marco Concor Supercomfort. It has dropped sides to relieve any chafing and a big relief channel to help take the pressure off down below. It has a little bit of a wave design for those who like to be stationary on the bike.
