Bought this Emonda SL8 in 2016 I always rode my fixed gear bikes really never road the Emonda much I wanted to do conversion but I had about 8K invested in it and would be a crap shoot with vertical drop outs if I could find chain length that would work turns out 15x50 was good I filled all the cable holes and front derailleur indentation on seat tube and it rides great.I had Mack make me custom hubs so that I was able to use my Bontrager 50 mm carbon rims.Garbaruk 1x chainring for my 9000 Dura Ace crank
