Derailleur and Roadlink Question

[MudLark]

Hi guys,

I would really appreciate a little bit of help if anyone is able to point me in the right direction.

A while back I bought a used Specialized Diverge – an older model but it suits me well. It is a very light bike for what it is and comes in just on 8 kg. It's been used a fair bit and has a few bumps and knocks but overall is in great condition. It has a Dura Ace system but I don't know which version. Below is a picture of the rear derailleur. If anyone could tell me which Shimano model number it is I would be grateful.

The other thing is that I want to get a larger cassette onto the bike. I am thinking of maybe fitting an 11/34, which for me would be great for climbing steep hills at the end of a long ride (say 120 km plus). Would a Wolftooth Roadlink be the right solution and would it work in context? Is there any other similar product which is readily accessible that I could look at as well?

It looks to me like some sort of cover or cap has probably gone missing where that circlip is. Does it matter? I couldn't care less about the aesthetics.

Thanks in advance!

Get a Shimano XT or Deore mtb 9 speed derailleur. Even medium cage will work with 34 cassette. It is hard to find 10 speed road derailleurs in good condition. Many mtb 9 speeds don't look bad and will work on road 10 speed setup. 10 speed mtb derailleur will not work on 10 speed road (Shimano).

I'm no expert, but I did see this on Rapide's site the other day and assumed it did the same job: https://www.rapide.co.za/product/rapide-derailleur-hanger-extender/

That is a DA9000 RD will go up to 28T

Indeed it is.

The roadlink will definitely be required, or the item from Rapide.

Hi guys,

Many thanks indeed. That is very useful info. It looks like the Rapide link should do it for me. Will get hold of Wayne.
