Shimano 105 RD-5800 11SP Rear Derailleur

Shimano 105 RD-5800 Rear Derailleur

Setting a new bar in the trickle-down technology trend, Shimano 105 5800 brings uncompromising 11-speed road performance to the more budget conscious rider. With a foundation set firmly on the success of Dura-Ace and Ultegra, Shimano's 105 5800 group is a workhorse component package that can hang with the best the industry has to offer. Powerful improvements across the range deliver optimized drivetrain and braking performance that will instantly take your riding to a whole new level. There are lots of flashy, distracting contenders out there, but if you're main focus is getting down to business, the new Shimano 105 group is ready to log some overtime.

Shimano didn't just limit their redesign of the RD-5800 to increase the gear range, but while they were at it, they added a new spring balance and cable pitch, increasing potential for adjustability. With the RD-5800 rear derailleur, shifting is crisp and predicatble and adjustment is as simple as it gets. The SS (short-cage) version allows for use with cassettes up to 28t, while the GS (mid-cage) version stretches to reach cassettes up to 32t. The Shimano 105 RD-5800 rear derailleur offers reliability and workhorse performance at a price point that won't even get close to breaking the bank.

Shimano 105 RD-5800 Rear Derailleur Features:

  • 11-speed
  • Improved shift accuracy
  • New spring balance and cable pitch
  • Lighter action
  • SS (short cage) for cassettes up to 28t
  • GS (mid-cage) for cassettes up to 32t

Excellent Upgrade
Used to upgrade an c1980's Schwinn. Installed a triple crank and 7 speed mega gear freewheel and needed the longer cage to handle the chain slack. Shifting was smooth and precise. The dérailleur is easy to adjust.

PROS: Easy To Install, Attractive Design, Lightweight

BEST USES: Road Biking, Upgrade

105 just works
Needed a medium cage rear mech after upgrading to a 32t rear cassette. Seems to me that pairing this with a KMC SL chain works better than the Shimano Ultegra chain.

You need this for a 32 cassette
My bike came with the SS version and 28 cassette. You need the GS if you want to run a 32 , and I do!

Smooth Shifting
Upgraded to the 5800 groupset and couldn't be happier. Quality components. This RD is a huge difference over the older tiagra it replaced

Is this clamp on or braze on?
Tim G on Jan 18, 2017
BEST ANSWER: This is a rear derailleur, and is going in the derailleur hanger in the back of the bike. the front derailleur is the one that's is clamp or is braze on, that' s depend of the type of the bike. If you have more questions is better to go to your local bike shop and see the difference.
