Replacement Sora Lever Body?
 
I cracked the right lever body on my older Sora 8 speed brifter (ST-3300). I hate to throw a perfectly good shifting mechanism and have a possible lead on a Sora 7 speed brifter. Does anyone know if the 2 lever bodies are compatible? Thanks, all.

If you do come up with a replacement body, you may have difficulty transferring the parts to it without ending up with a pile of tiny, incomprehensible bits that you have no clue as to how to put back together.

I'm with dsbrantjr here. Shimano brifters aren't typically designed to be rebuildable. Although if you get ahold of a body with a busted rachet-shifter mechanism, then by all means try. I just don't think your probability of success is very high.

I believe the OP was asking if the lever/blade/pod is transferable. Not the internals of the pod. Shimano often uses a common platform across a number of models and years of production with only finish and hardware differences denoting the various models. So the lever body (the part that connects to the bars, holds the lever/pod at the pivot and has the hood over it) (Shimano has called this part the "bracket" at times) might be used in a few different levels or a cross a few years. If your particular example does is any one's guess without actually looking carefully at how the lever/pod pivot and mating shapes match up. Shimano is not going to offer any help here. So my answer is to go to your LBS and look at their bikes in for repairs or check out fellow club members bikes that have the same lever as the one you're wondering about. Then compare the lever/pod shapes and pivot details and make your own judgments. Andy.

Andy is correct - sorry for any confusion. Although I have rebuilt older STI units before, I'm only wanting to transfer the lever & internals to a different lever body this time. So just a simple fix involving an Allen bolt, a pivot pin, and a spring, plus hopefully a replacement body. The lead fell through, however, and nothing from my LBS so I haven't had an opportunity to check. I don't want to toss an otherwise decent shifter - aargh!

How do you rebuild STI's? I was given got two sets of decent-looking 7 speed RSX brifters. They seemed to click through the positions OK on the bench with no cables in. When they were mounted on the bike and cabled up, the right hand levers (rear mech) would only pull one click from top gear (smallest to second smallest sprocket), then stop. Now back on the bench I can't get the levers to the position to take the cables out. Is the fault in the lever ratchets, with the (new) cables, or something else? How do you dismantle these things or is it a case of have to buy new ones? The left levers (front mech) seem to work fine with the same new cables. Any ideas?

I had a guide from some old roadie magazine that showed me how to do it. I believe if you do a search on this site, there are several members that have done it and have provided guidance. Luck. Now to try and find a broken lever somewhere....
