Shimano RS505 Shifters - want a clutch derailleur

[Butterbean]

So, ive googled like made, read tech docs, and cant find a conclusive answer.

 

I have 11 speed RS505 hydraulic brake shifters on a gravel bike, and its running an 11spd GS cage RD from the factory. Id like to have an MTB RD on there with a longer cage and clutch, to expand my gearing options.

 

Current gearing is 48-32 front, 11-36 rear, and I'd like to go to at least a 11-40 as a bailout gear for these WC hills... I don't want to change the front gearing, and I'm not interested in 1x.

 

Anyone know what RD will suit and be compatible?

I'm running 34/50 up front and 11-34 out back and went with Ultegra RX800, comes with clutch...works like a charm...11-40 may be a push though

I'm running the same parts on my Specialized Sequoia and recently switched to an 11-40 cassette by adding a derailleur hanger extender.

 

Doesn't unfortunately answer your question about a clutch derailleur but it's a cheap easy way to extend your gearing options.

Thats great news! Same bike, so thats a better solution. Would still like a clutch for future but at least good to know the extender will help with the gearing!

I suspected you might be riding a Sequoia given the specs.

 

I hope you've changed the wheels to something less similar to solid cast iron train wheels [emoji38]

Those Hayfields that come with the bike are ridiculously heavy, plus the hubs gave me issues after almost no mileage.

I literally have a set of Rapides about to ship to me... I cant wait - 800gram saving! The bike rides so great but the wheels really do hold it back if youre not touring. Cant wait to feel it with proper wheels on there.

 

Fortunately i havent run out of gears just yet, but i worry about the longer rides where tired legs need a bigger granny. So will see whatsup.

Good to hear, enjoy!

 

I've done a number of multi-day backpacking trips with the bike fairly loaded and the mtb wheels (1800g or so) that I replaced the Hayfields with, have been bombproof.

Just recently did the Cederberg circuit fully loaded with camping gear at over 25kg bike weight and I didn't have any issues (I'm 80kg). Actually, that's what prompted the 11-40 cassette. The 11-36 would've been tough that heavily loaded.

Quickly phone Rapide on Monday and add a rear hanger extender to your order, they stock them.
