Hi, Chapa
I’ve had 3 Synapse – all Hi-mod – a 2013 rim brake (which i sold to a friend who has used it for everything from day to day riding, to bike packing trips, including an 8 day Strade Bianche tour in Tuscany – he loves it), then the 2015 rim brake one with the split ST, and then the DA disc one – thought the 2 rim brake ones were great but that the disc one was just a bit underwhelming – but all sold now
I also have a 2013 Supersix HM, with 38mm Wheelsmith wheels and Ultegra 6800 – wouldn’t sell it for the world – brilliant bike that I’ve done everything from racing to 100 milers, and its never failed to disappoint.
Just wish I’d bought the HM disc last year instead of the Synapse ☹️
Just my tuppence worth.
