Description

An advantage against the clock

We're proud to say that we still believe in mechanical shifting. And even though Di2 makes sense for when you're locked into the time-trial-tuck, you simply can't beat the feeling and reliability of 'real' shifting. That's why the Shimano Dura-Ace SL-BSR1 11-Speed Bar End Shifters are the perfect addition to your wind-cutting steed. The aesthetics are stunning, the feel is unparalleled, and even better, all of the new additions work symbiotically to achieve the perfect harmony between your body and the bike.

It's too easy to go on and on about the SL-BSR1's 11-Speed shifting option, and while it adds a powerful advantage over the field, we know that the new Dura-Ace shifters can't be defined by one feature. Dwarfing all other advancements, however, is the shifting itself -- this is where Shimano's 'Rider-Tuned' philosophy really makes itself known. This is the title given to Shimano's campaign of providing you the best rider-experience of your life. Throughout the group, every component has been given little custom touches, but the levers have received several. The the required effort has been lessened by around 47% for the rear derailleur and 43% for the front derailleur. In tandem with the reduced stroke, the shifting experience has been minimized to light touches that pit mechanical and Di2 shifting speed toe-to-toe against each other.

Not surprisingly, the mad scientists at Shimano weren't satisfied with simply making the smoothest mechanical shifting in their history. Instead, the bar was set even higher, and Shimano aimed to make the shifting effort seamless across every sprocket of the cassette. That's right, effort has been equalized, regardless of if you're moving across the bottom or moving across the top of the cassette. Even more obsessive, Shimano decided to also equalize the actual feeling of shift throughout the cassette. If you're familiar with Shimano, you'll know that in prior Dura-Ace generations, down-shifts felt more like 'dropping' the chain down the cassette, rather disproportionately in comparison to moving up it. No longer. Now, with Vivid Index Technology, down-shifting feels just as crisp, engaging, and as smooth as up-shifts. This is due in part to superior mechanics, but in the larger scheme of things, it's more attributable to something as simple as proprietary shift cables. SL-BSR1 uses Shimano's exclusive polymer-coated shifted cables. We know that it doesn't sound like a big deal, but the new cables play a key role in the near-elimination of mechanical drag, and they also provide a flawless shift performance.

The Shimano Dura-Ace SL-BSR1 11-Speed Bar End Shifters are available in one color and one size. Please note that these shifters are specifically designed for use with Dura-Ace 9000 components and Shimano's polymer-coated and PTFE cables.

Read in an article that the new 9000 Dura Ace 11 speed cassette is the same spacing as the 7900 Dura Ace 10 speed. 11 speed is a just a little bigger cuz of extra gear. I'm wondering if I can use these bar ends in Index shifting and just not use the the last shift and limit the rear derailleur so it won't go past the 10th cog?

Responded on

That is not recommended because the pull ratios are different and it would not shift well. If you need 10 speed shifters, email me at mfarr@backcountry.com and I'd be happy to get you some ordered.

Can you use these in the friction mode...

Can you use these in the friction mode with a 10sp cassette?

Best Answer Responded on

You can convert the rear shifter to a friction shifter so your 10 speed cassette will work. Let me know if you have any other questions on compatibility- msfarr@backcountry.com
