Code: BR5800-Black
Shimano 105 – 5800 rear brake callipers, 49mm drop, black. Featuring an updated design of the symmetrical dual pivot calliper, with a higher arch allowing clearance for up to 28 mm tyre type.


The Shimano 5800 has gone 11 Speed for the latest incarnation of the 105. The 5800 has been inspired by the innovations of the more upper end Shimano Ultegra and Dura Ace; you can see the technological influences across the design of the 5800 components.  More advanced and lighter than its predecessors and with a more eye catching design, the 5800 promises high performance and is one of the latest cycling must haves. 


  • Enhanced brake arch proportions give a quicker linear response and increased power
  • Must be used in conjunction with ST-5800, ST-6800 or ST-9000 STIs for correct leverage ratio
  • Dual-pivot calliper brake with super SLR-EV design for quick linear response, increased rigidity and improved braking power
  • Low profile outer cable stop position improves cable routing for reduced friction
  • Cartridge brake shoes for easy replacement
  • Convex washers on the brake shoes offer toe-in brake adjustment and easy alignment
  • Lightweight aluminium construction, with an anodised finish to preserve the good looks
  • Compatible with 28c tyres
  • 49 mm drop

General information about our shipping
Purchased these to replace the awful calipers on my allez. They certainly make a difference in terms of performance, not a massive one but better none the less. The main advantage is the ease of adjustment compaired to the tektro, for anyone with an entry level bike I'd recommend these as an upgrade. As ever great service from merlin.
Brought these an a upgrade to some stock brakes on my winter bike. What a difference these made, strong braking which gives me a lot more confidence now.
Strong, reliable and responsive brake set. Set up right, these do the job perfectly.
Upgraded the brakes on my wife's Orbea, and she says that she didn't know that brakes could feel so good, strong and easy to modulate. Four thumbs up!
Good looking brake clamps , replaced a Tektro 580. Tried them out on a mountain descent over the weekend, the pads seem to be more rigid than the swisstop salmon I previously had, which were all weather and softer. Will give the pads more tme and see if I need to replace them altogether.
The Callipers that I bought with my bike were insufficient so I changed them for these brake Callipers of Shimano 105 from Merlins instead. I would recommend this product to anyone who wants to stop well in all weathers of both wet and dry. Excellent product!
Excellent callipers delivered with the usual excellent Merlin service. Not as light as the Tektro units they are replacing but way more powerful with greater modulation and feel.
Powerful brakes, significant upgrade
A little heavier than the brakes that came on my Cannondale but have double the stopping power and have good modulation and at the price that Merlin are selling these for make them a deal
