Pro bike: Tony Martin's Specialized Shiv TT

World champion set to defend on an S-Works

German Tony Martin helped drive the Omega Pharma-QuickStep team to victory in the 2013 World Championship team time trial on Sunday aboard a Specialized S-Works Shiv TT. It was not the first worlds win for Martin, nor the first aboard a Shiv. Here we take a look at the bike he rode this weekend, and will mount again Wednesday to defend his individual time trial world title.

While UCI rules specify that frames must be available to the general public and not one-off models, there are a few unique aspects to Martin's rig. For starters, he runs an enormous 58-tooth chain ring (paired to an 11-26 SRAM Red cassette). And the German is also on prototype Specialized S-Works clincher tires. While nearly all professional riders race on tubulars for road events, a select few choose clinchers for time trials as they can offer lower rolling resistance. Martin's mechanic pumps his 24.2mm tires to 8bar (116psi).
