STI style shifters on CX bike?

Is anyone out there running/trying to run 10 speed STI shifters on MTB components?

Just wrote an email to Gevenalle regarding compatibility of their CX shifters with MTB components. Here is what they said, "...maybe we will have something that will remedy this situation on the 15th". I'm not sure about you, but I'm excited.

Unless anyone knows of any STI style shifters which already exist for drop bars that would work with newer MTB derailleurs and cassettes?

I love Gevenalle but I'm not entirely sold on the need for MTB components. I guess if you're doing serious off-road climbs you need a lower gear than 34-30, but that gets me just about any place I want to go.

To your question, I think SRAM's 10 speed shifters always worked with their 10-speed MTB derailleurs.

All of the SRAM "Exact Actuation" 10-speed components are compatible. I run Rival shifters with an X7 Type 2 RD on my CX bike and it works great.

My local LBS told me that the rear derailer will work with brifters but the front derailer will need to be switched to a road one because the pull is different on a mtn bike front derailer. I'm planning on using my mtn bike rear derailed on my gravel conversion and trying the front to see if it works. Not that I don't believe my LBS but I have found that there is a lot you can do that the industry doesn't says you can't do.

Shimano 10-speed MTB rear derailleurs don't work with Shimano 10-speed road shifters, but their 9-speed MTB rear derailleurs do work with their 10-speed road shifters. The front derailleur is fairly incompatible but you can kind of make it work, especially if you set it up as a double.

Not true. I'm running a Shimano XTR front derailleur with Shimano Ultegra brifters. Works great.

Is this just a CX bike type you want to have Low Gears on ? not racing ..

Racing doing the hills in a low gear you may watch the field, running the hill, pass you buy ..

On a triple or a double, road or mtn crank? I tried setting up a Trek 520 with Ultegra 10sp shifters and the triple front shifter would not play nice with LX derailleur/Deore triple crank. Had to go to a road triple FD.

Currently, I run 105 10sp shifters with 9sp XT RD, Ultegra FD, VO double crank.

I would think the real advantage of mixing mtb with road components is the lower gearing you get with a trekking crankset. I'm running STIs, 3 x 8 STs, and road derailleurs with a mtb crank (44-32-22). Getting the front derailleur to work took some tweaking but it works. I'm not running anything fancy though just Claris STIs and derailleurs with an older Ritchey mtb crank.

It's a compact double. Funny though, I've had really good luck with old Deore FD's with road triple cranks. On one bike I have a Deore FD with a Sugino XD2 crankset with a Ultegra 10sp shifters and it works fine. I haven't used MTB cranks though so that may be the difference.

this is what I'm doing. 3x8 mtn bike cranks and derailers with Claris sti shifters. I'm not to sure how the derailers will work but I'm going to give it a shot.

Well... if you can't dial in the front shifting, a Claris 2403 FD is only $25 or so...

I'm running Shimano 105 5700 STI levers, with a double crankest, FD-CX70 front derailleur, and a 9-speed Deore XT Shadow rear derailleur with an 11-36 cassette. The combo works great - definitely stick with a shadow-type 9 speed Shimano RD if you want to run a wide-range cassette. The more modern 10-speed Shimano mountain rear derailleur's wont work with 10 speed STI shifters.

It is nice being able to spin up a steep hill at 4 mph, and not spin out until 30+ mph.

How old? I have a Deore LX (circa 1989) front derailleur that works with road shifters but that's because it was made before Shimano changed the geometry of their MTB front derailleurs to introduce the incompatibility.

Using a MTB front derailleur with road shifters and a road crank gives you a double whammy in that the curve of the FD isn't optimized for the ring size. That's less of a problem than cable pull ratio though.

I've got my Long Haul Trucker set up 3x8 with a 44-36-26 crankset and a 12-28 cassette. I like this gearing a lot for non-competitive riding. I'm using bar end shifters right now, but I've been tempted to put Gevenalle levers on it. The only thing really holding me back is the traditional touring look of the bar end shifters.

Indexed shifting and triple cranksets should never have been brought together. Even the best STI triple with a plethora of trim stops is a compromise compared to a friction-based shifter.

I'm looking for the big MTB range for a touring/off road mix. If whatever Gevenalle was hinting at doesn't work, then I'll probably just go for a 12-30.

I wouldn't say that; it implies that the bike shop doesn't know what it's talking about, when it does. The cable pulls are different, so you shouldn't expect it to work (and in most cases, it won't). Sometimes you get lucky.

IRD Alpina FD with Shimano 9speed MTB RD.

Too bad Campy dropped the micro-ratchet design in 2009. I can live with indexing though, it's the weird Shimano design of triples that tends to be problematic when you mix and match parts. https://janheine.wordpress.com/2013/0...h-sti-triples/

I think it's pretty old. Not sure how old, but it's old. That's on my bike with the Sugino triple. My Moots has a compact double and it's got an XTR FD and it's fairly new. Both bikes shift quite well but I agree with you about the triple and STI. I do have to tinker with it from time to time.

If they are saying that it doesn't work, then I'd say they are incorrect. It does. Maybe not all the time, but it does work. Both my bikes have MTB FD's and I've had better luck with it working than with road bike FD's. But yes not all MTB FD's may not work. I've not found any but my experience is limited.

whatever gevenalle might be working on, my guess is it'd be more about chain retention than gear range. like fiestbob pointed out, you don't necessarily need more gears for cx racing. given the company's dedication to cross, this would make the most sense.

The beauty of the Gevenalle system is that cable pull is very simply determined by the size of the cylinder in the bar end shifter bit. A lot of people run 1xX setups with Gevenalle, so as 9-speed Shimano MTB RDs become more and more scarce there is a CX application for 10-speed Shimano MTB (not to mention SRAM) compatible shifters. Did you see the Gevenalle/SRAM setup that the guys at Sellwood Cycle cobbled together?

So it doesn't surprise me to hear that something is/might be on the way.

Taiwan sources are eager for business .. shipment takes 2 weeks to cross the sea. + container sorting and Customs clearance once they hit the west Coast.

Microshift moving the Detent Points in to the right spacing for another RD/Cassette combo .

wonder if they might supply you guys extra detent rings? though whole new levers are probably low enough cost ..

most of the business retail margin is taken stateside.


As far as Will mixes of FD from MTBs work , 'Devils in the Details', I cant rehash what has been posted before , but you can search it Out.

this exactly. there's clearly a market for it, especially on the shimano side.

those boys at sellwood are very clever and do some nice work.
