A few weeks ago, Si dusted off his old Specialized S-Works Tarmac SL3 from back when GCN started in 2013 to compare it to his 2023 Canyon Aeroad. Predictably, it was much slower, but we got lots of comments asking to test it again after fitting it with modern deep section wheels and fast tyres. So, that’s what we’ve done. Old bike with new wheels and tyres - how much faster is it?
