Item # SHI002V

Fast and accurate shifting.

If you've been jealous of your 11-speed-convert friends, but just haven't wanted to smash the piggy bank open to buy a new groupset, the new Shimano 105 5800 group is what you've been waiting for. The 105 ST-5800 11-Speed STI Shifters feature technology that has trickled all the way down from Shimano's Dura-Ace line, but in a more affordable package.

The first thing you'll notice about the 5800 group is that, yes, it does have 11-speeds. Drawing from the popularity of the Dura-Ace and Ultegra groups, the 5800 is now compatible with the new and improved CS-5800 for a full range of 22 gears. Unlike the last iteration of 105, the new STI shifters feature a more compact and streamlined lever that fits into your hand. It is also adjustable for reach so that your hand-to-brake interface is secure. The shifting mechanism itself draws inspiration from Shimano's top-tier groups, with shorter strokes and polymer cables for faster, more accurate shifting.

The biggest noticeable difference between the 105 shifters and their big brothers is that the levers are alloy rather than carbon construction. This, as well as alloy verses lighter weight titanium bolts, increases the weight of the shifters a bit from the top-tier models.

The Shimano 105 ST-5800 11-Speed STI Shifters come in one color and are available as Left, Right, or as a Set.

105 = Awesome

  • Familiarity: I've used it several times

I bought these shifters as part of a 105 groupset to put on a spare frame I had laying around. I decided to go with 105 because the 105 has had a history of being Shimano's workhorse group and this 11 speed group is priced great, which leaves money for wheels or cockpit parts. Every component within the group got a good upgrade and resembles features found on the higher priced 11 speed Dura-Ace and Ultegra groups. The 105 groupset also allows for a pretty easy gear configuration if you're interested too (11/32 cassette, long cage rear derailleur & a 50/34 crank). If you're on a budget or want a group for a training bike, the 105 11-speed group is no-brainer option.
