I'd like to get the Shimano Deore 610 Groupset 3x10 but want to run drop handlebars with brifters (brakes & shifters combined) but it seems like this is almost impossible...

I've been told by one support person from the online site I'm buying from that I can use 105 brifters and front deraileur and this might be compatible. I've been told by another support person to just go Tiagra 4703 but I really would prefer V-Brakes (descending the Alps), the lower gear ratios (climbing the Alps) and the €100 saving of the Deore.

I know I've got two issues, gear indexing and brake cable pull ratio but is there any brifters that will allow me to use Deore successfully without huge amounts of faff?

Thanks...

  • Maybe something like an SRAM 2 x 11 groupset would help, The offer up to 42 tooth cassettes now so are great for climbing.. Brifters are all based around double chain rings. Triple chain rigs are at less common now, as doulbes can almost do the same job.. – Kim Ryan Jul 12 '15 at 23:34

  • Not an answer, but I'm quite impressed with the triple on my road bike.... 26 front and 24 rear. That works out at 2.1 metres per rev. To get the same on a 32 front you'd need 29-30 rear, and a 36 front chainring would need ~33 on the back for the same ratio. If you separated your brakes and your gears, you have to separate problems to solve. Otherwise its one single problem with many details, where the solutions are going to be uncommon/expensive. – Criggie Jan 10 '16 at 1:17

Unfortunately, You can't use 10 speed shimano road brifters with 10-speed dyna-sys mountain bike drivetrains. They just have different cable pull ratios.

Your limited to a few options if you want to run drop bars with 10-speed shimano:

  • Mount your existing MTB trigger shift on your drop bars. This means you have to take your hands off the hoods and drops to shift.
  • Get 10-speed dyna-sys compatible thumb shifters from microshift. You must take your hands off the hoods and drops to shift.
  • Get 10-speed dyna-sys compatible bar end shifters from microshift. You must shift from the drops.
  • Get Gevanalle GX brake/shifter kit, you must shift from the hoods using indexed bar end shifters mounted on front of brake levers.
  • You could try road brifters and a long cage road derailleur with a 10-speed mountain casseette. Definitely unsupported by shimano. May be limited to 11-32 cassette instead of 11-34 or 11-36. YMMV.

    However, you can mix and match road an mountain components with most sram 10-speed drivetrains. So you could use something like force shifters with x9 derailleurs with less trouble.

    • Also, a new option is to try something like the wolf-tooth road link with a road shifter which changes the derailleur position a bit allowing for a wider range of shifting on a mid-cage / long-cage derailleur for larger range cassettes. – Benzo Oct 19 '18 at 20:44

    No -- You've got several problems here. 10 speed mountain Shimano has different cable pull than 10 speed road Shimano (which is the same cable pull as 9 speed mountain Shimano, I believe, so if you double check this, you can drop a 9 speed Deore in). Then, you have the mountain vs road FD, which if you're using brifters, you need to use a road FD. Front derailleurs are cheap anyway, so I don't see why you'd want to save money here.

    The V-brakes are pretty easy to deal with with a travel agent (a pulley to let you use short pull levers with V-brakes) or you can use mini-V brakes and not use a travel agent.

    The newer brifters (such as the Tiagra 4703) are "Super SLR" on the brake pull amounts. This means they work even better with Mini-V brakes than older brifters that had the gear cable coming out the side.

    You can get Tektro and TRP's in several arm lenghts -- depending on what you are looking for in your setup. 80mm (926AL), 84mm (TRP8.4), 85mm (BX3V,BX1V,RX1,RX3,RX5), 90mm (TRP9.0,RX6). Typical Shimano MTB V-brakes are 107mm.

    The longer the brake arms the less force you have to apply to the levers, but they also require you to put the pads closer to the rim so you don't run out of brake lever travel. Shorter arms give you more rim clearance, at the expense of mechanical advantage.

    I highly suggest using V-brake noodles with an adjusting barrel to make releasing the straddle cable much easier for wheel changes.
