Retroshift’s CX2 Shifters Review: Prioritizing Reliability and Simplicity for the Mud and Muck of Cyclocross

Pin It

As we enter the sloppy period of the cyclocross season, some of you may have suffered from gunked-up or broken shift levers and races hampered by unreliable drivetrains. If you’re on a budget and prefer reliability over conformity, Retroshift has an alternative shifter and brake lever combination worth considering. This review by Andrew Yee originally appeared as just one of many products reviewed in Issue 17 of Cyclocross Magazine, available instantly via uberflip or the Apple Newsstand. Update: The $189 Retroshift CX2 has been updated since our review and now comes with 9 or 10-speed Microshift shift levers standard, and the company offers a CXV for V-brakes and $139 CX1 for single ring systems)

 

Adam Clement, the man behind Retroshift, is a tinkerer. For nearly two years I’ve seen photos and prototypes of his shifting system. Being someone who, as a poor college student, bolted a thumb shifter to his drops when his Shimano STI brake/shift lever (“brifter”) broke, I admire Clement for thinking creatively to find an alternative to the three main brifters we have to choose from (Shimano STI, SRAM DoubleTap, and Campagnolo Ergopower).

Why bother with an alternative? If you’re already wondering this, you’re probably not Retroshift’s target market. But if you’ve ever broken or jammed a shift lever in a cyclocross race or on a long ride and had your day ruined, you might want to keep reading. By simply naming his company Retroshift, Clement already makes it easy for racers to self-select into one of two groups: those who will scoff at his contraption, or those who will be at least curious as to whether Retroshift might be worth trying. If the name doesn’t scare you off, chances are you might remember a day when shift levers were made up of just a few parts; didn’t rely on multiple springs, carbon and plastics; and would never been rendered useless by a race in deep mud or sand, or by a simple crash.

Even though one of my cyclocross bikes still has a bar-end front shifter on it, after pulling the $189 Retroshift CX2 out of the box, I was still skeptical as to whether the idea of bolting a Barcon or down-tube shifter to the front of a brake lever made sense, especially because such levers do not recenter themselves. And unlike with a Barcon or down-tube shifter, you can’t just change your hand position to execute the shift since your hands are already gripping the hoods. Would I be able to reach the lever in every gear? Could I shift in a sprint? Would it get in the way of braking? I installed the 10-speed CX2 levers on a vintage ’cross-able Trek road bike that split time between fat slicks and knobbies, and I promptly entered a NorCal mixed-terrain race.

As luck would have it, it was probably the wettest day of spring, and a mixture of road grit, dirt, sand and silt built up in layers on my bike as the hours went by. The Caveman (Erik Tonkin, pro and shop owner) saw my levers at an aid station and gushed at how well they worked for him last season. I thought it’d take me most of the ride to get used to the shifting, but I found I didn’t need more than 30 seconds to get used to the levers. I never missed a single shift and never felt that the levers got in the way during some deathly scary, “hold on for dear life” slimy descents. After one ride, I was convinced Clement was onto something for cyclocross, mixed-terrain and adventure applications.

Now that CXM tester Clifford Lee and I have spent several months on the levers, we have much more specific impressions about them. We absolutely love the right shifting and find that we can execute every rear shift easily from the hoods. Shifting from the drops is difficult, if not impossible, but it’s quite rare that I need to do so in cyclocross or in any other types of riding I do on my cyclocross bikes. Sure, during a tricky sprint in the drops for 22nd I might miss the chance to upshift, but such a situation is actually quite rare and is not the dealbreaker it’d be if I was a criterium specialist. The beauty of the system is that you can do multiple shifts, including the full range, with a single lever throw, and when something happens to mess with the indexing (mud, cable stretch, a bumped derailleur hanger or a wheel swap), the levers allow you to nudge the shift lever to complete a shift in a way that a ratcheting system won’t. And then there’s always the ability to shift on the fly to friction mode. I personally liked the CX2’s rear shifting so much that they’d absolutely be my levers of choice for a 1×10 setup if I was building the bike from scratch. At $139, including a rear shifter, the CX1 levers are an affordable way to cover your braking and shifting needs without being stuck with the extra weight of a front brifter, or the burden of needing to sell that front brifter and buy a single left brake lever.

The CX2’s left shifting took much more getting used to, partially because I paired it with a vintage Shimano 600 front derailleur that requires more cable pull than a modern front derailleur. The “default” installed lever position had me unable to throw the lever enough to even make it into the big ring. But the beauty of Retroshift is that anybody with a fl at-head screwdriver can quickly customize the levers. I simply rotated the shift lever on its mount outward by 90 degrees, and suddenly front shifts were much easier, plus the infinite trim options of the Barcon lever meant no chain rub in any gear combination. Still, because the lever had to travel quite a distance in one motion just to pull enough cable to execute a front shift, it never felt very quick or confidence-inspiring, despite the fact that my fingers are quite long. I felt like a bar-end shifter would be capable of a slightly faster shift (since you can use your whole hand), but of course would require taking your hand off the brakes. Clifford’s test unit originally came with down-tube shift levers, which worked fine, but he opted to swap them out for some Shimano Barcons he already owned, enjoying the change in ergonomics and appreciating the rubber covers of the Barcons over the all-metal downtube levers. However, in the end he preferred the spring-assisted front shifting of the left down-tube lever.

The neat thing is that the possibilities with Retroshift are quite endless. Find a 6-, 7-, 8-, 9-, or 10-speed index down-tube or Barcon shift lever that also runs in friction mode, pair that lever with Retroshift, and you can grab almost any old rear wheel and go for a ride in friction mode (provided that the rear hub spacing works with your frame and your chain doesn’t fall through the gaps in that 5-speed freewheel).

This capability could be a lifesaver on race day if you grab a wheel from the pits or a buddy that’s not a perfect match with your exact system. Down-tube and Barcon shift levers are so basic that you can easily devise a cable sheath/shim that changes the cable pull per shift. Early Ultegra 6400 7-speed levers had such an accessory—a small plastic piece that partially filled the cable groove, allowing you to also use 6-speed freewheels. There’s no reason you or Retroshift couldn’t build an 11-speed lever with tiny cablepull altering accessories that would allow you to use 10-, 9-, 8- or 7-speed cassettes. After sharing this idea with Retroshift’s Clement, he said he might even consider it. Not a Shimano fan? Retroshift has a Campagnolo system in the works and is looking at SRAM options (although Retroshift will work fine with SRAM cassettes when combined with a Shimano rear derailleur). Clement is also working with shifter manufacturer Microshift to provide another Shimano/SRAM-compatible option.

If you’ve got a component sponsor, mechanic, pit crew and backup bikes, chances are that Retroshift won’t appeal to you. But if you have ever broken a brifter in a race, have had one jam up with mud or sand, are on a tight budget, or don’t want your success to depend on a tiny spring and ratchet when you’re miles (or an international flight) away from home, then Retroshift is worth a serious look. Considering the weight of the shifters and brake levers, Retroshift is lighter than bar-end levers, easy to set up and intuitive to use. Paired with a sealed cable system like Gore’s (discontinued) Ride-On Sealed Low Friction, you might just have the most weather-resistant drivetrain next to a singlespeed.

Seems this system will be great on a touring bike..... I have a Trek 620(85) with the Tektro levers and Dura Ace 9 speed bar end shifters. 

Would love to have those bar ends moved to my levers. Great idea!

Will this system work using self-centering thumb shifters such as those made by SRAM? I see that is the best of both worlds.

Sometimes you can tweak a friction front derailer's action by mounting the cable on the wrong side of the mounting bolt -- the closer to the pivot the cable is mounted, the less cable pull needed to execute a shift (however the force needed will increase -- travel and leverage have an inverse relationship). Sometimes this trick is helpful to get proper action out of shifters and FDs that were not designed to work together. It doesn't affect the lever's position as a possible bonus.

 

BTW, if you use barcon levers with plastic covers, they WILL come off -- it's just a matter of time. No worries, though. Just put a few wraps of thicker cloth tape -- cotton bar tape or rim strip in a pinch -- and then cover THAT with electrical tape. It might not win any beauty contests, but it works like a charm and prevents a cover-less barcon from hurting your hands. For bonus points, you can try to super glue the plastic cover on to prevent (or delay) it's loss.

Maybe not the intended market but I could see these be awesome for commuter cross bike applications. All the convenience of simplicity at an affordable price. Will have to keep these in mind when I get around to rebuilding my fair weather (non-winter) commuter.

 Was not mentioned by Adam but we have also since review made some changes to the Tektro brake levers.  When we re-assemble the units the stock pivot bushings used are discarded and replaced with a sturdier set that result in a more solid fit of the brake lever in the main body.  This is unique to our levers and not provided in the stock offering of this lever or from other companies that sell this lever.

If (at 41, I'm beginning to think it's more like when...) I ever decide to forego single speeds for CX, this will be the system I use.

When I first raced 'cross in the late 90s, I used bar-cons, and this is a huge improvement without the disadvantages of integrated brake-shift levers.

Maybe I'm turning into a curmudgeon, but I like the idea of a simpler, less expensive solution.

Thank you CX Mag for such a great review! - Who can argue with a review that says it would choose Retroshift CX over the shifters offered by the big names!  - We are thrilled!  I will just say I am a fan of all the other shifters out there and for use on the road will likely recommend the big names over our product BUT for CX you now have a system built specifically for the conditions we love - Mud & Abuse.

 

Just a couple of notes I think will be of added benefit to anyone looking at CX shifters as an option:

 

1.  While one of the benefits of the system is the ability to use it with such a wide range of older parts (even vintage gear as Andrew did) it really should be used with current derailleurs to get intended performance.  If used with a Shimano 9 or 10 speed front derailleur you will get incredibly fast and effortless front shifting PLUS the ability to trim the derailleur (Dura-Ace won't even do that!).

 

2.  We are now offering our own shift levers (Made by Microshift - who have been great - thank you guys!).  These levers are custom made for us to our specifications and are not the same as the stock offerings.  Please note that stock Microshift levers will have issues if used as part of the system.

 

3.  Weight.  At 388 grams CX2's sit comfortably at about 50 grams under the weight of Ultegra 6700.  With our shift levers you will save a few more grams.

 

4.  While our system is considerably less expensive than our competitors integrated shifters there is also a further additional savings.  If you crash and mangle a shifter (any amount of damage) we will re-build the unit (left or right) back to full operating condition for just $24. The amount of money that can be saved racing with CX shifters will allow you to spend the money on liter wheels/tires etc (build a faster bike).

 

5.  American manufacturing and assembly.  Patent pending parts are engineered by Mark Dinucci (you are a god Mark, thank you) then machined, anodized and laser engraved by a small herd of goats here in Portland, Oregon.  Tektro levers we utilize (from the super wonderful people at Tektro - we love you!) are disassembled and worked on here also before being re-assembled.  All time consuming and skilled work that we are proud we have done right in our backyard/Portland.

 

Thank you all who have already made the jump and for all the great feedback.  Our system is very much a product of the weekend races and we will continue to develop it with racer feedback.

 

Cheers,

 @ChadRector We are very much focused on making the best shifter possible for the wilds of cyclocross.  That said we are confident that if it works for cross it will probably do just fine with anything else you can throw at it!  Maybe with CX shifters you might even concider building a 'foul weather' commuter  :)

 @adamclement 6.  Unlike Paul's top mounts (which I use) your system can utilize any diameter handlebar.

 @TyDaC   Love Pauls Thumbies!  Really no comparison between them though.  Apples and oranges - One is a thumb shifter one is an integrated shifter.

 @Retroshift Okay, I take back my offensive compliment--don't want to get you guys in trouble with the boys from Chico.
