Good to see they're narrowing the gap with SRAM. Only a couple of years behind now 😂

This groupset? Why, yes. Yes it is.

Ohhh. I thought he was just affirming that he had a groupset: "This, groupset? Yes, yes it is".

well done Shimano. Could be interested in the mech if it's remotely backwards compatible and doesnt need a gravel specific cable pull.

Other than the FM calipers, I think I'm in.

Finally, a double chainset with asensible number of teeth

good stuff. Was nearly going to have to go with Eagle NX that wears faster than you ride.

If Shimano price it around sram prices or just above they have a winner ! Obviously more for inline levers etc.

I'm hoping (assuming) that the new front mech will be compatible with 105 brifters. I can see me getting the double chainset and mech to give me a lower ratio for sure.

Should be compatible with 5800 and R7000 shifters.

It's compatible with existing 11 speed Shimano road stuff.

Details are already up on the [url= https://bike.shimano.com/en-EU/product/component/grx-11-speed.html ]Shimano Europe site[/url] (from the Components drop down menu under Gravel & Adventure).

Looks like their are 10 & 11 speed options.

I'd be interested in trying a double on my Swift; would it work with a MTB (73mm BB shell - the Shimano bumpf mentions 68 or 70mm)?

Does anyone actually want chicken levers apart from bso buyers? Descending on the tops is scary with no leverage over the steering and all your weight in the wrong place!

Not entirely sure anyone needs that much front gear range, 50-11 with 700x23 is a high gear, 48t with cx tyres is going to be hard work indeed! And a 16t gap is going to make chain lines awkward.

Some of the smaller options look usefull though, but why not just offer a triple? It's uncool but basically the same thing just with closer ratios.

Finally a 1x for CX though.

I'd like the 30/46 chainset on my road bike. I'd then swap the 11-32 cassette for a 11-28. I like the lower gears, never need 50/11 but would like closer ratios.

Just like a 50/34T doesn't?

I’d like the 30/46 chainset on my road bike.

New chainset needs a new front mech due to the chain line.

I know the cable pull is different but is Shimano 11 speed spacing the same or close enough between their road and MTB 11spd cassettes? Or have they ballsed that up as well?

edit: internet says yes but MTB 11 spd cassette width same as 10 in which case I should be able to fit 11spd mtb cassette on my pro2 evo hubs.

very useful for riding along fully loaded with very wide flared bars. they are nearly flat bars with drops on. use my ones all the time bikepacking

Well if they have, then so have SRAM. Cos Shimano and SRAM MTB 11sp are interchangeable (other than the freehub design), and both have different cassette pitch for road 11sp.

With the exception of 1 Ultegra branded cassette which is MTB spacing?

Dunno about the new GRX spacing... assume it's road?

Freehub dimensions differ, but sprocket spacing is the same AFAIK.

I'm using an 11spd SLX cassette with Sram force shifter and rival mech.

Have Shimano fixed their leaking piston/caliper problem?

Not entirely sure anyone needs that much front gear range,

Lots of people are quite keen on sub-compact chainsets already it's interesting that shimano have taken that particular thing up where SRAM haven't...

I also note that if someone were to combine that 48/30t chainset with the 10t sprocket (Micro Spline type cassette) that shimano have already released for MTBs, they could create a wider range drive than a current Road compact or standard doubles can, replicate or exceed the range but maintain some usefully narrower steps in the cassette... I can see something derived from this appearing on road bikes soon.

But yeah I'm not a fan of the chicken levers, but they're not there for me, other people will want them and it's a bit of a USP for Shimano now...

New chainset needs a new front mech due to the chain line.

Question is then would that work with my 105 5800 sti lever. I could use a Praxis 30/46 but that would need a new BB.

Thanks for the confirmation, I realise I could have read through the article but knew if I put out a speculative question someone would have done the thinking for me `:-)

I have wide range 1x on my gravelling cycle but if I had a more dedicated roading bike then that 2x chainset + a closer ratio cassette would be ideal.
Have been doing some speculative sums and can't see less than £400 for a switch to 11 speed and hydraulic brakes even with a mish mash of bits unless I can pick up some second hand stuff

Interesting that there are 2 or three spec tiers within the same ‘GRX’ name

I wonder if the chicken / cross-top levers would work ok with DOT4/5.1 and so could be used in a SRAM setup?

i can see the chicken levers being popular for Paris- Roubaix where they often ride on the tops?

The Miche Graff crankset should work with your existing levers, mech and BB.

FWIW I mailed Tredz to see if the various delivery dates they show are estimates or fact and they said it's just what the supplier (Madison I guess) provide.

As much as I like the look of the levers, I'm mainly interested in the mechs and they look pricy compared to the MTB equivalent

Cross-tops also useful for descents where you may need to bunnyhop or navigate very steep sections.
