Shimano's 105 lineup has been delivering smooth, reliable drivetrain performance for years. This rear derailleur has a larger chain wrap capacity, which is great for running compact or standard cranks. It's also got a wider link design to help with shifting under load.
Stiff, wide outer link reduces flexing to deliver smooth, crisp shifts, every time
10-speed SIS wide link design improves longevity
Compatible with wide gear ratios (11-28T), which is great for beginner cyclists and riding in hilly areas
Comments about Shimano 105 5700 SS Rear Derailleur:
Replaced old unit on my daughter's 70's 19 1/2" Raleigh Grand Prix. Really slick install and adjustment is a snap. Greatly improved shifting and she uses down tube controls to boot. Handles 13-28 rear and 48-34 front with no problems. Smooth little unit way beyond what I started out with in the late 60's. Shimano has surprised me with a quality unit in this price range.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
