Sora ST-3500 STI levers with V-brakes?

I've been thinking about converting my commuter/touring bike from 9s barcons and linear pull drop levers to the new Sora 3500 brifters. According to several articles I've read, the levers can be converted between road and linear brake ratios via some sort of shim that modifies the brake pivot. But the Shimano tech website doesn't have any information online other than the exploded view which is inconclusive.

Can anyone confirm whether these levers work with V-brakes? If so, are they user-convertible, or do you have to buy the right version?

There are levers out there that convert but the ST-3500 levers are not those levers. You can use a Travel Agent to correct the pull ratio or use cantilevers or mini-V's, both of which match the pull ratio of the ST-3500 levers. Another option is a road-version mechanical disc brake like an Avid BB7. I use one up front on my commuter (rear cantilever as my frame isn't disc compatible and I rarely use the rear brake anyway) and I will never go back to a rim brake for bad weather riding. You will need a disc-compatible fork and front wheel of course.

[edit] I decided to Google this and saw that Bike Radar actually did mention using regular v-brakes with the Sora STI levers. I can't find anything on Shimano's site that supports that ability though and wonder if something got lost in translation at the press release.[edit]

As far as I know the Sora ST-3500 are be use with road brakes only ,and the shim you are referring to are to be use to move the lever closer to the handlebars to be use by people with small hands . I hope this help .

Yes, that's one of the articles that I saw. Re-reading it, they only refer to mini-V's, which I think use road ratios. The wording is confusing, and I agree it reads like a translated press release. I do have some decent cantis that I can convert over to, so it would only be a little more work.

Quote from the article: "The Sora levers can also be used with standard V-brakes, mountain and road cable discs, cantilevers and roller brakes thanks to a 'mode converter' chip at the lever pivot."

link: http://www.bikeradar.com/us/news/art...st-look-33204/

I can find nothing on Shimano's site to support this statement though and can only assume that the "mode converter" chip is the shim to which bikeman refers.

Oops, my mistake. The article that mentions "compact V" brakes was from a different site:

They're talking about the Sora flatbar levers being compatible with v-brakes.

You have a few options here:
1-install the brifters with travel agents. Come back on this forum a week later for tips on how to tune them, b/c they'll prolly feel yucky. Tweak em a bit, and either learn to live with it or switch to a different set-up.
2-install the brifters and get some cantis. Spend half of your commute each day wondering to yourself why you "upgraded" to worse brakes and worse shifters.
3-spend a lot of money on some compact linear pull brakes, like the Paul Mini-Moto, or slightly less money on the Tektro version. That might actually not be such a bad idea, except for the part where you're rockin' Sora brifters. With that thumb button. And all that plastic. And little hope of ever rebuilding them, once they die, in a few thousand miles.
4-spend a lot of time searching for an elusive gizmo that will somehow turn short-pull levers into long-pull levers. The part may not exist, and it may not work well if it does exist.
5-save some money, and keep all the awesome stuff you have in place already. Enjoy reliable, serviceable shifting and powerful brakes, with some slightly mushy feel at the levers.

Sora 3500 levers ditched the thumb button. I liked it better than the dual lever arrangement except for when using the drops FWIW.

I put nearly 10,000 miles on a set of Sora 3300 brifters and they worked perfectly the whole time. They are as repairable as any other Shimano brifter too (not very).

I have both. There is no mode converter on the STIs that I can find, but there is on the flatbar levers. They both work with compact Vs and Canti's which is nice if you want to go between flat for short rides and drops for longer rides.

Ok, makes sense that there is an option for both brake styles on the flatbar levers. Shimano has done that before. The article was misleading with its vagueness as to which style of lever has the mode converter. Thank you for clearing that up.

I got my Sora 3503 levers a week or two ago (Ribble has a really good price on them, BTW). I haven't mounted them yet but I can confirm they don't seem to have any mode converter, just some inserts for reach adjustment. I guess the only question remaining is whether they use the "old" road brake ratio or the new generation ratio that the 5700/6700/7900 and above use.

Just handling them, I like them so far. The shift action feels solid and not plasticky or clunky (again, this is without being connected to a drivetrain). I kind of like that they retain the simple, old school external shift cable routing but have the new hood ergonomics. Sort of the best of both worlds. We'll see how they hold up once I get them set up.

Folks need to get with the program. There's an easy way.

Remove the lever:


Take the front off:


Reveal the crucial screw:


Voila. This is as far as you have to disassemble.

That's an old STI mechanism (newer ones are more complex from what I recall) and "as far as you have to disassemble" is very dependent on what is broken. I have a few broken STI levers that required almost complete disassembly to get at the broken components (for which I have yet to bother finding replacements).

I've overhauled quite a few pairs of STIs and it's almost the same procedure for any dual-lever external cable STI, only the details vary.

For instance, on ST-6500s you have to pop off a plastic cover to see the bolt rather than peel off a badge, that sort of stuff. NBD.

There are basically three varieties of STI, details aside, and each one's principles of operation and overhaul are fairly consistent across all the different models.

Original, with the exposed cable and two levers. Original Sora, with the button. And the new aero type, which unlike the Sora variant is almost a complete redesign. Haven't had a chance to tear into some aero ones yet.

I can tell you the overhaul procedure you can find via the link in my tag is good for all exposed-cable STIs, probably even the buttoned Soras to some extent (it's been a while since I worked on some). And that it'll be completely useless info regarding the aero STIs (except that they have little pawls which eventually stick).

Ok, so you disassembled and reassembled. I don't call that an overhaul. Unless I missed it, you didn't replace any worn or broken parts, and that would involve finding a donor set of levers as spare parts are not available, hence my statement that Shimano levers are not very rebuildable.

If you have a source for spare parts, I have two right 10 speed shifters, one Ultegra and one Dura Ace, plus one left 10 speed Dura Ace that could use some help.

The earlier shifters seem pretty durable; the only problem with all the first-generation STIs I've worked on has been sticky grease.

I sorted out a pair of crash-damaged Soras by bending bits straight, they didn't need parts.

The 9s Ultegras I'm currently using required me to tweak a couple of springs in each to prevent them jamming, and that's about it. Never found broken parts inside an STI.

Yet to crack any 10s ones open though.

BTW, I'd say disassembly that most won't attempt, and cleaning and lubing that restores function most definitely counts as an overhaul.

Also, unless Shimano totally dropped the ball (which they occasionally do in some regards) concerning the mechanism's design, the non-aero 10s levers will be no more fragile than the 9s ones.

The aero levers on the other hand, I've seen a few reports of the linkage between the lever and the now-internal shifter breaking, so there's that ball rolling away again...

I've encountered that too and sorted it out with half a can of WD-40.

You're luckier than the guys who I got my broken 10 speed STIs from then. I'll have to take some pics of the broken parts one of these days. If I only had a laser cutter at my disposal I could fix them, but unfortunately set up charges to pay someone else to do it make it uneconomical.

Ok, my hang up is that the disassembly is largely unnecessary in order to restore function though I'm sure doing it that way allows for a longer lasting restoration.

IMO it's an epic PITA trying to degrease and lube an enclosed mechanism, and cleaning is mostly precluded.

Easier to crack it open in my book. Avoids getting degreaser on the hoods (or having to remove them) too.

I read it the same way before I bought. I was hoping I could just do a swap kit with vbrakes between drop and flat because I prefer flat bar on my daily ride. Long rides I want drop. Ended up getting short v's and changed the chip on the flatbar levers, but almost went Canti. In the long run, it's probably a quicker change out with the V, but it would have been cheaper not to have to buy a set of Vs because I had an old set of deore's laying around which were better than what came on the bike.

It's a nice set up. Easy to adjust, stays tuned. Have had zero problems with the STIs or the flat bar config. Really happy with the choice. The gearing is nice and was able to use the short rear. Have the compact double crank with 12-25 in the back. Have a lot of hills on every direction and it's more than enough range. For upgrades, I use 105 BB cups, ultegra 9 chain, and an ultegra 9 cassette. Bought a spare of the chain and cassette in case I need them later on an Amazon sale for $50. Couldn't pass it up.
