It\u2019s sometimes said that Shimano\u2019s budget-minded Tiagra groupsets function much like Ultegra from a decade before. Perhaps proving that to be true, Shimano\u2019s latest Tiagra R4000 road group is now 11-speed, disc-only, and with a number of familiar features. \u2028 <\/p>\n
I\u2019d been wondering what Shimano\u2019s plans were for keeping existing bikes with its 11-speed road components in service, but unfortunately, this new Tiagra isn\u2019t quite the answer I\u2019d hoped it would be. Still, the components are sure to appear on a bunch of lower-priced road bikes, and with a new 11-36T cassette, there may still be something for those already on Shimano 11-speed road shifting.\u00a0<\/p>\n
I got hands-on with the new components to test cross-compatibility. Let\u2019s take a look.\u00a0<\/p>\n
The basics\u00a0<\/p>\n
With Shimano Claris and Sora now phased out in favour of the CUES range<\/a>, it\u2019s Tiagra that’s left standing as Shimano\u2019s most budget road-specific groupset label. Tiagra R4000 now sits between 105 and CUES U6030.\u00a0<\/p>\n The new Tiagra R4000 makes the move to 2×11-speed \u2013 one more gear than the previous-generation R4700. Gone is the option for rim brakes or mechanical disc brakes, as the new Tiagra is now hydraulic-disc only.\u00a0<\/p>\n Those new levers look and feel exceptionally similar to the mechanical-shifting and hydraulic-braking 105 R7020 and Ultegra R8020 before them, which is to say they don\u2019t feel like a budget product. The scales also suggest as much, with the new R4020 levers weighing almost exactly the same as R8020s at 289 grams each. Compared to those Ultegra levers, the new R4020 have a subtly narrower profile.\u00a0<\/p>\n New Tiagra R4020 against Ultegra R8020. <\/p>\n There is now just one rear derailleur size (274 g): a long-cage model designed for the new R400 11-36T cassette. Shimano already offers that range for 9-, 10-, and 12-speed, but until now, not 11-speed. That cassette features an aluminium spider, and at 392 g, it\u2019s lighter than previous-generation cassettes at this price point (a 105 HG700 11-34T 11-speed cassette is 365 g). The cassette has a fairly even gearing progression of 11-13-15-17-19-21-23-25-28-32-36T.\u00a0<\/p>\n Up front is a familiar-looking crankset that\u2019s available in 50\/34T or 52\/36T. Crank lengths are 165, 170, 172.5, and 175 mm. And shifting those chainrings is a compact toggle-style front derailleur (95 g, braze-on version) like what we\u2019ve seen with previous mechanical 105\/Ultegra\/Dura-Ace.\u00a0<\/p>\n The new 11-36T cassette. Meanwhile, the crankset looks much like the previous R4700 version. <\/p>\n There are no new chains here, with the pre-existing HG601-11 being the official match. All of Shimano\u2019s 11-speed chains remain compatible.\u00a0<\/p>\n Groupsets of this level often exist to fill OE (Original Equipment) demand. As such, international aftermarket pricing is still to be confirmed.\u00a0<\/p>\n ModelUSDGBPAUDEuro<\/p>\n Shimano Tiagra R4020 shift\/brake lever – Sold per end $240TBC$300 Cross-compatibility explained\u00a0<\/p>\n Most unexpected is that the new derailleurs and shifters are interchangeable with CUES U6030, but not any of the previous generations of Shimano 11-speed road or Tiagra 4700. The reason? Shimano increased the cable pull ratio for the new Tiagra.<\/p>\n This post is for subscribers only Already have an account?
