is thtis something i can do on my own? anyone done it? thoughts? help? anything else you can add?
anyone?
Maybe if you got more specific as to what the problem is…
Shouldn’t be a big deal. Shift onto the big cog and big chainring, then push the levers down (without pedaling) so that the cables are slack. Unscrew the bolts that go through the lever, pull the lever off the long nut (and push that out the shifter body), but pay attention to where the ring on the body is oriented. This last bit is important – if you don’t kleep it in the right position, it won’t index right when you put it back together (or you could just run friction mode and not worry about it). Anyway… Once this is out of the way, you slip a long allen wrench into the lever body and loosen the binder inside the aero bar. Remember, this loosens REVERSE of everything else – to the right. That’s because you’re backing out the bolt, not the nut. Slide the shifter body out, and you’re free to swap out the bars. Reverse the process to re-install.
Done it dozens of times. Just watch how it comes apart and get it back together the same way. Its really no big deal.
if you have internally routed cables, you’ll have to loosen the cables from the derailleurs and pull them through.
even that (with a possible derailleur adjustment), is no big deal. it’s actually real easy to learn, and can REALLY help you if something is off the night before a race.
