Which Groupset?

Zinn wrote "The derailleur’s shift-activation ratio is different for Shimano 11-speed rear derailleurs than it is for Shimano 10-speed rear derailleurs."

Maybe that's just for road then.

Anyway, now I just need to find the sexiest 9spd RD and a 10spd 11-36T cassette.

WTF is "Reverse Spring, Low Normal" and does that matter if it's being attached to road shifters?

Reverse spring or “Top Shift” in Shimanospeak means the spring is pushing the chain towards the larger cogs. Shifting is opposite of normal. It’s a pain in the ass and didn’t catch on.

It’s a pain in the ass and didn’t catch on.

Though it makes way more sense.

Or Rapid Rise!

I stand corrected!

It makes more sense to pull the derailer onto smaller cogs, and let the return spring push it onto bigger ones? Yeah nah

Trying to help a friend with the hills who has a 9 speed R3000 groupset that came 48/32 and 11-34. Loaded touring and gravel, doesn't need big gears.

Option 1 - Roadlink and 11-36 cassette
Wolftooth don't mention if their RoadLink extensions are 9 speed compatible but they do say "Optimised for 10/11 speed" so might work. An even wider cassette would go beyond the RD capacity.

Option 2 - Crankset/chainrings
Can switch to FSA 46/30 rings or splash out on a Shimano GRX RX600 46/30 crankset.

Option 3 both!
11-40 cassette and 44/30 stays within the RD capacity. Assuming I can find a 44t 120 bcd chainring that is compatible.

Can a GRX mechanical rear derailleur be used with 6800/9000/8000 shifters ?
edit : looks like it

Yep, gf is using one with r7000 shifters

I am looking for a GRX di2 gearset, has anyone seen any for sale?

Hen's gold dust mate. Better off with Ultegra Di2 shifters and brakes with an XT Di2 rear mech.
Looks better and there's no gravel tax to pay.

Yeah I really only need rear derailleur, brakes and shifters. Got the other big bits.

We had a few but anything "on demand" just goes into new bikes. I'll ask tomorrow, see if I can sell something.

There is some stuff abotu so don't worry too much. Just thought it might be cheaper to by a gearset and sell the front D than buy all the bits individually

Anyone selling 12 speed shimano yet

I got a GRX Di2 rear derailleur and shifters/brakes not that long ago. Shifters were from Merlin and derailleur was from ProBikeKit, I think.

Thanks. Have you seen a full wiring kit? I can't see any, maybe it doesn't exist, which is unhelpful.

Never seen a full wiring kit. I just buy the wires separately so I know they're all the correct lengths.

Has anyone seen any Sram Force AXS groupsets or gear sets out in the wild?
Looking for a set with flat mount brakes but they're like hens teeth at the moment. Some places saying September 2022 for delivery!

I fitted a sram gx axs rear derailleur and shifter to my mtb, after the xtr shifter broke again 5th one in 2 years, thought it was time to see what it was like. I'd previously sworn off sram 4 years back.
Anyway, sram axs on a shimano cassette and chain shifts better than xtr shifter did. I won't go back.

Plus wireless is just so damn easy.

I'll probebrly build it up with hope brakes. But I've never had issue with shimano brake so far, so no desire to use sram shif brakes.

But I've never had issue with shimano brake so far

It's all personal choice but even though I get a nice discount at Hope, I use Shimano brakes. I like their light action and power. Hardly any maintenace either and mini-bleeds are super easy.

Yeah. I forgot, I did actually have a trail caliper fail, the pistons started leaking. I liked the idea of hope being fully replaceable.

How much of a bad time am I going to have if I try & run a non-clutch R8000 rear derailleur 1x on my CX/gravel bike? Front shifter breaking has introduced some x1 necessity :(

It'll be alright, depends how rad you're getting, narrow/wide chainring will mostly keep the chain on fine, you might get a bit of chainslap on the stay if you're bouncing around on rough stuff.
