Compare bar end shifters and STI levers on cost, repairability, and hand position. See where the Dura-Ace SL-BSR1 fits and which setup suits touring or road riding.
Quick answer
Choose bar end shifters if you want simple, repairable shifting for touring or mixed-terrain riding; choose STI levers if you want integrated braking and shifting without moving your hands. The Dura-Ace SL-BSR1 is a strong bar end option when you need an 11-speed rear and 2-speed front setup.
Where bar end shifters win: simplicity and serviceability
Bar end shifters put the mechanism at the end of the handlebar, away from brake pivots and cable bends. That layout makes cable replacement and lever swaps straightforward, and it lets you run a friction mode on many models if you prefer to trim by feel. The trade-off is that you move a hand off the brake hood to shift, which matters on fast group rides or technical descents.
Where STI levers win: integrated control and hand position
STI levers keep braking and shifting under the same hand, so you can shift without leaving the hoods or drops. That integration comes with more internal parts and usually higher replacement cost when a lever is damaged. If your priority is staying on the brakes in traffic or a paceline, STI has the edge.
Friction vs indexed bar end shifting: a practical exception
Indexed shifting gives repeatable gear changes, while friction lets you trim the derailleur across a wider range of cassette or chainring combinations. Friction is useful on touring bikes with mixed drivetrains or when a bent hanger makes indexing unreliable. The cost is that you must learn the feel of each gear, and shifts are less precise under load.
Trade-offs at a glance
- Cost and replacement: Bar end shifters are generally less expensive to replace than STI levers, and the Dura-Ace SL-BSR1 set is listed at USD 67.50. STI levers integrate brake and shift mechanisms, so a damaged lever often costs more to replace. Budget for the lever you are most likely to damage in a crash.
- Hand position while shifting: Bar end shifters require moving a hand to the bar end, while STI levers let you shift from the hoods or drops. Choose bar ends if you accept that reach; choose STI if you want to keep both hands on the brakes. Ride a bike with each setup if you are unsure how often you shift from the hoods.
- Drivetrain compatibility: The Dura-Ace SL-BSR1 is index-only, 11-speed rear and 2-speed front, so it suits a double chainring and an 11-speed cassette. If you want friction shifting or a triple chainring, look for a different bar end model. Confirm your cassette speed and front chainring count before ordering.
- Handlebar fit: The SL-BSR1 fits handlebars with an inner diameter of 19-22mm. Measure your bar ends before installation; a bar outside that range will not work without a different shifter or bar. Measure the bar's inner diameter, not the outer diameter.
Product facts
- Dura-Ace SL-BSR1 Bar End Shifters: The right-side/rear shifter is 11-speed, index-only, and the left-side/front is 2-speed. This makes the set a direct match for an 11-speed rear and double-chainring front, without friction mode.
Dura-Ace SL-BSR1 Bar End Shifters - Dura-Ace SL-BSR1 Bar End Shifters: All bar-end road shifters produced after Nov 2008 have an I.D. spec fit range of 19-22mm. Check your handlebar's inner diameter before buying, because a bar outside that range will not accept the shifter.
Which setup fits you?
Best for
- Touring and mixed-terrain riders who value simple repairs and lower replacement cost
- Riders with an 11-speed cassette and double chainring who want indexed bar end shifting
- Cyclists who prefer to set cadence by feel and do not need to shift from the hoods
Not for
- Road racers and group riders who need to shift without leaving the brake hoods
- Riders who want friction shifting or a triple chainring, since the SL-BSR1 is index-only and 2-speed front
- Bikes with handlebar inner diameters outside 19-22mm
