There's four SIS HOY essentials packs worth £143 each too, and 40% off for every road.cc reader!...

Competition alert! We've teamed up with Science in Sport to offer you the chance to win a HOY Sa Calobra .003 worth £1000! Plus there's four SIS essentials packs worth £143 for the runners up and 40% off for absolutely everyone. How's about that?

HOY bikes are, of course, the brainchild of six-time Olympic champion Sir Chris Hoy. "Chris has had a longstanding relationship with SiS and has been using our products for many years", say SIS. "As our Elite Sports Consultant, he works closely with SiS and our team of experts in hydration and nutrition, with the aim of using his experience to refine our world class nutrition products."

We tested the Hoy Sa Calobra .003 back in 2013 and found it had a "Very nicely put together aluminium frame and a level of performance that's hard to beat". So that's nice. We've got one of those to give away, and four lucky runners up will get a SIS HOY Essentials Pack worth £143. That's got all sorts in it: loads of gels and electrolytes, plus recovery products too. It should last you a while.
