Details
Fits to your current derailleur hanger to extend the hanger further allowing use of much larger cassettes.

In some cases this means you can use a short cage derailleur on a 11-40t cassette! Perfect for a single chainring set up on a gravel/cx/adventure bike.

I recommend this product
Further to my review of 11 Apr 2018, bike now set up with 32 teeth big sprocket. 44 inner ring as planned. Lovely low gear works perfectly. Amazing result for cost of only £4.99.

I recommend this product
Not fitted yet. Have classic Langsett 1957 bike with Campag ends incl. gear hanger, 49/44 TA Adaptor Set and Campag Gran Sport rear mech. with 14/26 capacity. I now need lower gears and hope the hanger extension will permit a bigger large sprocket. I'll report IDC. Ratings are provisional at this stage.

Triple (48-38-28) 11-34 to 13-40, If I ignore 48T Chainring?

Triple (48-38-28) 11-34 to 13-40, If I ignore 48T Chainring


Hi,

Thanks for your previous answer.


I currently have up front, a triple consisting of 48-38-28.

In the rear, my cassette is an 8 speed 11-34 and the Derailleur is a Shimano Tourney TZ which has a maximum cassette cog spec of 34T

I would like to upgrade my cassette to an IRD 8 Speed Elite 13-40.

In a previous answer you advised that:

“Generally triple set ups do not work with the Extender, the only way to tell with your specific bike is to test fit it.

The reason being is the rear derailleur simply is not capable of that amount of range. “.

However, I wasn’t ever planning on cross-chaining by using the big 48T chainring with the large 40T cassette cog (I only ever use the three smallest sprockets on the rear when using the big 48T chainring up front).

So with that in mind, would fitting this Derailleur Extension device present any problems?



Thanks in advance.
As our previous answer explains, the derailleur will not be able to cope with the amount of chain length change by using such extremes. It is best suited to single or double chainrings.

Thanks

Hi,

I currently have up front, a triple consisting of 48-38-29.

In the rear, my cassette is an 8 speed 11-34 and the B-Tension Screw is screwed in the maximum amount (and with screw thread to spare). The Derailleur is a Shimano Tourney TZ

I would like to upgrade my cassette to an IRD 8 Speed Elite 13-40.

Using your hanger adapter, would I be able to do that?
Generally triple set ups do not work with the Extender, the only way to tell with your specific bike is to test fit it.

Campag Record 10 Speed

Have a Campag Record 10-speed setup with a 12 - 28 cassette and 50/34 chain rings (SRAM crankset but who cares right?). I rarely ever use the three (12 - 14) cogs on the cassette. Aging knees beg for lower gearing. Would this allow me to run a wider range cassette and get lower gears leaving all else, inc. rear mech, in-situ? (trying to weigh up pro's and con's of a cassette change with this doodad vs putting smaller chain rings on the cranks)
Yes, except if the cassette still had 12t top the shifting at the top end would not be so crisp, also you'd have to be sure that the rear mech could cope with extra amount of chain to take up.

Hi there,

Generally triple set ups do not work with the Extender, the only way to tell with your specific bike is to test fit it.
We would recommend to expect you to be able to use up to a 36t cassette IF it does work.

Thanks
is it made of aluminium and if yes what kind ?

can I fit to a triple chain ring with 10 speeds campagnolo derailleur
Hi there,

From the information provided I cannot offer any advice, please specify exactly what you have / would like to have.

Yes the item is made from aluminium, it is not listed exactly which.

Thanks
extender adapter compatibility
By

I have 1978 Cartlton Pro 5 frameset with 5 speed campy v3 nouvo rear derailleur and 24/14 freewheel,,42/51 crank. Will the extender adapter enable use of 5 speed 28/12 freewheel or even bigger if there is one?
Hi there,

Yes this will allow you to use a 12-28t freewheel. Without testing its hard to confirm, but experience suggests this may allow you to use up to a 30t - you would need to test this in real life though.

Thanks
