In a move as reliable as clockwork, Shimano trickles down the same road racing tech developed first in their latest Dura-Ace, then Ultegra, now to the more affordable 105. Promising much of the performance of those more racing focused groupsets, 105 continues to be the value leader of Shimano’s road groups. You still won’t find Di2 at this level, but you get much of the same shifting and braking at a much more attainable pricepoint. The new 105 now gets its own disc brake components with an updated look, that once again comes in both stealthy black or more classic silver finishes.

Shimano 105 R7000 11 speed road bike groupset

While many of us may pine for a bike spec’ed with a Dura-Ace drivetrain, most bike build budgets stop quick with R9100’s cheapest group selling for over $2000. But at less than half of that you can get 105, and if you are willing to wait a couple of seasons, Shimano regularly trickles down much of their race-ready tech to what amounts to the entry-level of their top road components.

The new R7000 generation of 105 gets updates across the board, and a new look that is meant to follow in the footsteps of Dura-Ace and Ultegra. Shimano says that most 105 buyers aren’t necessarily looking to race, but want performance & reliability for all around road riding.

The biggest two changes to the new group are a more ergonomic set of hydraulic disc brake dual control levers, and the move to a Shadow rear derailleur with slightly wider gear ratios.

105 hydraulic dual control levers & flat mount disc brakes

The new 105 hydraulic levers will be a welcome departure for many from the previous RS-505 generation that 105 was assigned. While those older bulbous levers didn’t feel bad in the hand for most cyclists, the large lever bodies’ aesthetics were quite divisive. The ST-R7020 hydraulic dual control levers are said to take their more ergonomic shape directly from Ultegra’;s levers. They also offer the same updated reach adjustment as those levers  to better fir a wide range of rider hand sizes.

Since the hydro levers are a bit bulkier than a rim brake version, Shimano also even offers a second, completely separate ST-R7025 version optimized for cyclists with even smaller hands than the standard reach adjust range. These smaller dual control levers angle their uniquely shaped lever blades closer to the bar, and out at a slightly wider angle to still allow space around the smaller levers for a rider’s fingers without interference in the drops.


The new flat mount calipers are not a huge departure from the previous non-series RS-505 calipers that had previously been grouped with 105. They do get a slightly slimmer profile that is said to drop a couple grams while retaining the same braking, but also opt for more simple brake pads without cooling fins. And of course now they get silver or black options and 105 branding to match the rest of the group.

The rotors themselves aren’t especially new – using the existing RT70 rotors from mountain SLX, that pair an alloy Centerlock carrier to a stainless steel/aluminum/stainless IceTech sandwiched braking surface. With R7000 though, a new 140mm version of the rotor has been added. Shimano also says the new rotors are “UCI-compliant” for not having 90° sharp edges on the outside of the rotor, although they don’t adopt the more closed cooing fins of the Dura-Ace and Ultegra variants.

105 rim brake dual control levers & brakes

Inside both the new rim brake (ST-R7000) and disc brake (ST-R7020/25) dual control levers, the shifting internals were updated for faster, lighter shifts and a shortened lever stroke.

Those pair to new rim brake calipers with improved performance, increased tire clearance, and the option for traditional single bolt mount or direct mount variants.

105 mechanical front & rear derailleurs


The 105 front derailleur was already quietly updated last summer with a new pivoting design that copied Dura-Ace R9100 in order to get rid of the long lever arm to improve tire clearance, especially on bikes with short chainstays & wider, gravel-friendly tires. That new compact design (which skipped over last summer’s Ultegra update) carries over to R7000, with its easy to use cable tension adjustment replacing a barrel adjuster.

The 105 rear derailleur moves to the low-profile Shadow design adapted from mountain bikes, already found on Dura-Ace & Ultegra. This design tucks the rear derailleur more out of harm’s way (~12mm more inside) in the event of a crash, and adds Direct Mount hanger compatability. The new derailleur comes in two different cage lengths to work with either 11-25 to 11-30 cassettes (short cage – SS) or 11-28 to 11-34 cassettes (long cage – GS) much like Ultegra R8000.

105 cranksets & cassettes

105 also joins the other top road groups in offering a middle crankset gearing option, as well as slightly moving the inner ring to make for smoother & quieter operation while cross chained. Now 105 buyers can pick from standard road 53/39, semi-compact 52/36, or compact road 50/34 chainring combinations.

On the cassette side, 105 adds a new CS-R7000 11-30T option to the previous 11-28, 11-32 & 12-25 options. And there’s a new budget 11-speed CS-HG700-11 cassette targeting road plus, gravel, cross & adventure riding with an 11-34T range.

The new Shimano 105 R7000 components will be available starting in June 2018. The complete rim brake groupset is said to retail for $745/650€, with the disc brake group from $1130/890€.

        Swings and roundabouts mate, you guys pay a lot less for American brands; SRAM, ENVE, Niner, Stans etc 20-30% Trump’s trade may make war these differences even more extreme (I’m not looking for a political fight, just economics)

    • Bob on

      I hope so. i was just looking at the ultegra set and it is just outside my budget. it is not like US retailers have this stuff in stock anyways. and i have found that Chain can ship it to my door from Ireland faster then the LBS can get it in. I would be puting it on my bike anyways so why pay all that extra money.

  1. Crash Bandicoot on

    Very exciting, if the discounting is what it is normally from the online retailers than it would be hard for me to justify dropping the extra $$ for Ultegra R8000 outside of the shifters (the graphics on the shifters look like an afterthought). Any chance at all that Shimano comes out with 105Di2? There are a few di2 only frames out there for super cheap that I’d love to pick up and run 105 on.

    • SJC on

      The close-up pictures are the same (both are the disc version). In the pic of the full black groupset, the lower lever is the rim brake lever and the upper lever is the disc lever.

      • Cory Benson on

        Yes, the images did not get linked properly, but have now been updated.
        The image with two lever colors shows the rim brake version. The two black levers are the hydro ones, in regular & small hand versions.

    • Dinger on

      I suppose that depends if you’re a shop owner with a bunch of fresh, new 105 bikes on your shelves that you hoped to sell for profit this spring…

      • D-con on

        I can’t think of any shops that go big on Shimano, let alone groups at the end of their very predictable product cycles.

        If there are,I honestly don’t know what to say to make them feel better.

        • SJC on

          He’s talking about bikes specced with 105 from the manufacturer, not aftermarket components. Lots of bikes come stock with the RS-505 levers for the current 2018 models.

        • FFM on

          Shops don’t get to choose the spec on their stock bikes and that was a popular OE kit. The odds of this being available in June are realistically pretty low though and the odds of them hitting OE this season or pretty much nil so you’ve still got a good shot with the current crop of bikes. Chin up!

          • Dinger on

            I don’t think it will matter THAT much, but even if Shimano delivers late, now that people there’s a new group coming, I can’t see them buying the “old” stuff at full retail $, unless they simply don’t know..

        • lop on

          You seriously don’t know a shop with a bunch of 105 bikes on the floor? Have you been to a bike shop in the past decade?

      • Jones MacArthur on

        Do shops still stock drop bar bikes? I can count on my left hand the two road bikes and three ‘cross bikes we’ve sold in the last year. Contrast that with losing count of the many $5000 full-suspension sleds that have rolled out just this winter and early spring.

      • John on

        Shops have to know how hideous the RS-505 brifters are, not to mention that weird unergonomic bump near the bar where they moved the brake bleed ports.

    • Crash Bandicoot on

      There are significant limitations with 5800 12-25? I’ve been using this with a 53/39 for a few years and found it to be great for flat areas I figure if you need a 28t going up you’ll probably want the 11t going down.

      • David on

        I second this. If I were to buy a 2x gravel rig, it would have to be 46/30T. The difference between 50/34 48/32 is almost completely offset by large tires. The 30-34 gets very useful climbing up single-track or switchbacks. Of course, I went with Sram 1x because, well Shimano didn’t even have a RD that I’d consider three months ago.

    • John on

      Glad to see the 11-34 cassette designed for gravel, but when will Shimano get with the program and offer a super compact double chainring option? Really need that 48/32 or 46/30 please!

      • Jos on

        Yeah, so bored of waiting for this. 44-28 wouldn’t be too small either. Road kit at this level needs to be more than lower cost race specs.
        That new ultegra RD is good to see but max cassette size to go with it daft small.

  2. yard dog on

    Too bad no Di2. Thats the announcement I was hoping for.

    I’d like to see Di2 available on all Shimano grouppos. Tiagra, Alivio, Acera, Tourney, all the way down to the Shimano grouppos they put on Walmart bikes. But at this rate of trickledown we’ll never see it.

  3. Maples on

    Same pads?

    Fits: XTR M9020 M985, XT M8000 M785, SLX M675 M666, Road R517, Alfine S700, Deore M615 Calipers


    Fits: BR-R9170, BR-RS805, BR-RS505

    I dislike buying the finned pads, seems like such a waste not to re-use the fin bit with a new pad. Can of course be dropped off for metal recycling, but still just seems too Tassimo/Keurig/Nespresso-y.

    • typevertigo on

      They seem ever so slightly different.

      The MTB brake pads (G02A resin, J04C finned metal) have a slightly larger spread of friction material.

      The Flat-Mount brake pads (L02A finned resin, K02Ti resin, K04Ti metal) are a bit narrower. The non-finned K02/04 pads do look very similar to the non-finned G02As. Hope this helps
