Although i've been cycling quite a lot of years. Every bike i've ever owned has had Shimano shifting components. I've always been extremely pleased with the way they look and perform (especially the later groupsets). They are durable, reliable and spares are easy to find in any bike shop. My winter bike has a few lower end SRAM Apex components (although the shifters/mechs are still Shimano 105) and i've been very pleased with them. I also have another two bikes - one running Ultegra 6800 and DA9000. Both of which perform flawlessly (apart from front mech trimming which is something that has always bugged me) I'm planning my next N+1 road bike (more on that later) and am considering SRAM as an option. Can't really say why, i guess i'm curious and fancy a change. They seem good value (even more so compared to the new Shimano line) and the weight reduction is always welcome. Initially i'm pitting RED 22 vs DA 9000 or DA9100 here. Not entirely ruled out etap or Di2 but that would put the build into the startasphere price wise and it opens up the whole mechanical vs electronic debate (although the current Ultegra Di2 is a tempting proposition). Regardless of which tier groupset i decide upon, my primary concern is how i would adjust to the double tap (assuming i don't go etap) and how easy (or not) it is to adapt when you regularly ride different bikes with different groupo's. I'm also curious about the front mech - does the Yaw movement eliminate the need for trimming? as that would be a big plus in my book. (although i believe the new Shimano front mech goes some way to improving this). My other option is to go 1X but the jury's still out for me on that one. I've fiddled with various friends SRAM equipped bikes and have just ended up more indecisive than ever. As i said before i've always been a Shimano fan so It's not a move i plan to make lightly. Unless i'm 100% convinced, the 'safer' option is Shimano. Do we have any long time Shimano stalwarts that have made the switch to SRAM - or also own an SRAM equipped bike? What do you think and what are your experiences - both good and bad?
