Salsa vaya- Moving from a road crankset to a mountain one
So I've been riding my Salsa Vaya 2 for the last year and basically like it a lot. My only issue is that I find the Apex road group too highly geared for the bike. The 48-34 chainrings are just too big for a bike with 700c X 40 rubber, at least for this 60 year old geezer.
My local bike mechanic suggested swapping out my crankset for a SRAM X05 mountain double crank with 42-28 chainrings. This would bring my gear inch spread down from something like 118-29 to 105-24. He installed the new crankset and, sure enough, the new gear range is great. My only sacrifice is that I spin out at 35 or 36mph instead of 42, which is a complete non-issue for me.
However, my front derailleur shifting has gone to hell. The derailleur no longer has enough 'throw' to put the chain on the big ring unless the chain is already on one of the smaller 3 cogs in the back. Now my mechanic tells me that what we need to do is install a mountain front derailleur, which will presumably have more range.
But I have to wonder if my Apex road brifters will correctly mate with the mountain derailleur (I know the mechanic plans to use a SRAM derailleur... maybe an X05 or X07). Is the cable 'throw' of the Apex shifters enough to actuate the mountain derailleurs so they'll work OK?
If any of you experienced gearheads have any insight into this issue, please let me know. My mechanic has been quite helpful and knowledgable in the past, but I'm getting the feeling he's pedalling into unfamiliar terrain at the moment!
