How to choose the correct derailleur hanger - Part 1

2 September 2020
  • What is a derailleur hanger and what does it do?

  • You may see this vital component sometimes referred to as either a derailleur hanger, gear hanger, or even a mech hanger. But, they are all one and the same. The hanger is a consumable part that secures the rear derailleur to the frame. It's designed to bend or break in the event of a crash or impact that may otherwise cause damage to the frame itself.

    This guide is designed to help you find the correct Ribble derailleur hanger for framesets that are no longer in production. As with any hanger, we would always advise you to check your existing hanger against the ones listed below to ensure the correct fitting.


  • 1. Gran Fondo Caliper

  • This hanger is designed to fit Ribble carbon frames equipped with traditional rim brake calipers, circa 2010-2016. The hanger is compatible with the following models only;

    • Gran Fondo
    • Sportive 365
    • Sportive Bianco
    • New Sportive Racing (not to be confused with the later Sportive Racing model)
    • Sportive Azzurro
  • Pictured above: Gran Fondo, Sportive 365, Sportive Bianco, Sportive Racing, Sportive Azzurro


  • Various carbon frames circa 2010-2017

  • Designed to fit carbon frames produced between 2010 to 2017. This hanger is compatible with the following models only;

    • R872 (2017 Edition) – This frameset was the last of the range of ‘Stealth’ R872’s to be produced and can be distinguished from earlier versions of the frame by having a 27.2mm seat post diameter. (The earlier versions had a 31.6mm diameter seat post).
    • Evo Pro Carbon 2010-2016 – The first edition of the Evo Pro had completely round tube profiles, a visible carbon weave, a 27.2mm seat post diameter and was available in Black, Red or White.
    • Sportive Racing – With Matt Black or Green decals.
    • Sportiva Carbon – Rim brake version.

  • 3. Ribble SC61.10A/EM2

  • This hanger is compatible with a range of lightweight Ribble alloy framesets manufactured from Dedacciai tubing. In terms of aesthetics, they look very similar to the 7005 (section 4) and can be distinguished using the chainstays. Frames crafted from SC61 and EM2 tubing feature box section chainstays rather than the ovalised stays of the 7005 framesets.

  • The EM2 on the left was a limited edition, but it was identical to the SC61.10A Carbon Blacktail pictured on the right for all intents and purposes.


  • 4. 7005 SL/HORIZONTAL & CARBON BLACKTAIL

  • This derailleur hanger is designed to fit the 7005 SL sloping frameset, 7005 horizontal and 7005 Blacktail (alloy frameset with carbon seat stays) framesets. The chainstays will be ovalised rather than a box section, differentiating them from the very similar SC61.10A and EM2 framesets.

  • Pictured above: 7005 SL Carbon Blacktail, In terms of aesthetics, the 7005 SL is almost indistinguishable from the SC61 in the previous section.

  • 5. 7005 Audax Older Design

  • Only compatible with 7005 Audax framesets produced between approximately 2002 to 2010. This frameset requires a hanger with a single bolt fitting rather than the later twinbolt fitting.

  • Above Image: The 7005 Audax was a staple for dedicated cyclists looking to cycle through winter.


  • 6. 7005 Race (Horizontal)

  • Visually, the 7005 Race was identical to its sibling, the 7005 Audax (section 5). The only differences wer the 7005 Race lacked the mudguard mounts of the ubiquitous winter training bike and used a different gear hanger.


  • Compatible with the R872 (or Stealth as it was sometimes referred to) sold between 2012 and 2016. There were three iterations of the stelth versio of the R872, and this 3 bolt hanger is compatible with the first two editions. Compatible framesets will be equipped with a 31.6mm diameter seat post rather than the later 27.2mm version.

  • **Above Image: ** This earlier iteration of the R872 lacks the red R872 decals featured on the later version and uses a 31.6mm seat post.


  • 8. 7005/7046 Hanger

  • This hanger is designed to fit various Ribble alloy framesets circa 2011 to 2017. It's compatible with the following models;

    • Last edition of the 7005 Audax – Approximately 2011-2017
    • 7046 Sportive Horizontal top tube (not sloping)
    • 7005 Sportive
    • CR1 – An alloy cyclocross bike equipped with cantilever-style brakes

  • This updated Evo Pro was launched in 2017 and is noticeable for its distinctive White, Black and Lime Green colour scheme.


  • 10. CGR Alloy 2017

  • Released in 2017, this distinctive frameset was the predecessor to today’s CGR AL multi-surface frameset.


  • The Endurance AL was the entry-level model from the Endurance bike range that was first launched in 2018.


  • 12. Ribble SL

  • This ultralight carbon frameset was originally called the Ultimate SL upon its launch in approximately 2015/2016. It should not be confused with the Endurance SL, which was in production from 2018 to 2024.


  • 13. 7046 Sportive Curved

  • This hanger is only compatible with the 7046 Sportive Alloy frameset with a distinctive curved top tube design. It is incompatible with its horizontal tubed sibling (please refer to section 7 for the correct hanger).


  • 14. Sportive Bianco

  • This hanger is only compatible with framesets that require an internal fit hanger rather than the more typical external fit (bolts on from the cassette side of the dropout, rather than the derailleur side). Please check your bike to ensure it requires an internal or external fit hanger (please see section 2 for the internal fit version).

  • The HF83 was constructed from Dedacciai carbon tubing and was, for a time, the premium carbon frameset in our road range The hanger was exclusive to this frame only.
