Looking to upgrade the standard Axis wheel that came with my Specialized Tarmac ahead of Spring. I live in the flatlands towards East Yorkshire, but will be doing some hilly sportives. I think I'd value the reliability of alloy track braking over deep section carbon. I'm riding 3,000 miles a year max and won't do justice to something really high-end, plus I'd like to keep the price sub-£500. Current shortlist: Cero AR30 Evo - good press, a couple of guys in the club like Cero's carbon offerings Mavic Ksyrium Elite or Pro 2017 (non tubeless) - everyone's default option, but that has to be for a reason! Mavic's 2018 Ksyrium offerings which are now tubeless - might push the budget a bit, but is tubeless worth it? Worth mentioning I love the S-Works tyres that came as stock with my Tarmac. I look after my kit and am yet to suffer a p*nct*re on them (there, I've done it now!) Any advice or real-world experience welcomed. Cheers!
