Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

will be in stock in 2024 and no sub compact

Maybe current Ultregra then?

I don't want the full group. It'd just be shifters, cables, battery, junction, deraillers.

I really want to tear down my Mason and Kinesis and build a single bike with road and gravel wheelsets. Then I could use all the spare parts to convert her bike to Di2.

It works fine with your mech!

I've just put the wolf tooth in now and that has fixed it. It needed an extra quarter turn backed off the limit screw. Without it, it would do an upshift after a few seconds, presumably because it knew it wasn't quite on the big sprocket properly. I need to test it on a hill but it is working on the stand anyway.

The WT gives it space to get the extra quarter turn (and a bit more).

It's still really close to the spokes, though. I guess that is normal, just I don't usually look that close.

It has created another problem which is the cable is stretched really tight, which I'm not comfortable with. So I'll have to go fishing in the frame for the junction box and put a longer one on.

Unless Di2 extension cables exist... Which would save me half an hour's work at the expense of risk of water ingress and other failures.

Edit - looks like Di2 extension cables don't exist although plenty of other people are looking for them too! I'll have to fish the junction box out.

My Kinesis manages both with obvious compromises that it’s not really a gravel bike or a road bike… but it’s be got some carbon LB wheels with GP5000 on and some hunt wheels with something gravelly and a bigger cassette on. It’s enough.

What's the difficulty - clearance?

I put different wheels with 40mm off-road tyres in my road bike to do off-road last year. Worked fine, apart from it being when I smashed the mech....

yeah a mix of grx and ultegra maybe as the grx front mech will allow for cheaper/shimano sub compact

AXS. Much better range of gears, 1x or 2x, you can take the derailleur off for travelling.

That's what I've got on my road bike (shimano GRX sub-compact, 30-46). It actually works with ultegra front mech.

It actually works with ultegra front mech.

oh really?! interesting.

Yes, Shimano says no, but there's just enough adjustment. May depend on frame

In other news 11-36 cassette coming from Shimano

11 or 12 speed?

It works fine with your mech!

Didn't we do this last time and conclude that the mech itself was bent?

I would never extend a cable if I could do it "properly". Save some time now but cause bigger issues down the line.

Yes. Now I've got a new mech. But it needs the wolf tooth to work on my frame with the 42T.
I've still got your one on my shelf too, let me know when you're around and I'll give you it back.

Sure, I've started fishing for the junction box. Good chance to change the BB while I'm in there, but can't find the new one I bought a while back, so I'll have to buy another one.

I might be able to save a bunch of work and just go back to the 40T but I think there might have been similar issues with that as well.

Yeah, I do this already with my Kinesis - it has big 650B gravel wheels and a set of 700C road wheels.

But I want to lose the Kinesis (maybe leave it in Poland with the inlaws) and rather than have the Mason Resolution for road only, get something like the Mason Exposure and then have two wheelsets for that.

I could use some of my spares and some new parts and make the Sequoia Di2. Once I work out what BB I need, I will move the gravel cranks to the Mason and then put back on the 11-36T I used to use rather than the 11-42. That should give slightly nicer shifting, jumps and make packing it easier (and it's a bit lighter).

Might move the Quarq crankset to the Tarmac which currently has non-PM DA9000 cranks on it.

Not sure there is any issues. I guess not having enough Di2 parts and supply issues might be the blocker.

Did I imagine it or does GRX not have a road q-factor? Are GRX double cranks wider than road cranks?

AXS

There's zero chance of me buying SRAM groupset stuff other than their 11-36T cassettes.

Ooh, good point. I'm mostly in the 11s world. Forget they've trickled out their stupid 12s to road stuff now.

I guess you clearly like fiddling with stuff that doesn't quite work properly so that makes sense

I've had 2 issues with Di2 in 8+ years of using it, doing a lot more miles in a lot more conditions than most people. I've 3 bikes with it on. There's no way I'd move to SRAM. I'm trying to simplify my bikes.

You've seen the videos of WVA jamming his Shimano di2 chain for the 3rd time in one TDF stage?

FWIW I'm no SRAM fanboi, I have it it on only one bike (without a front mech), but bodging hangers to fit oversized cassettes etc that works nearly always is just a ballache.

GRX is +2.5mm either side compared to road.

I can't help that he has shit mechanics or keeps being crashed into. I've ridden around Spain with a 42T MTB cassette on the stock Di2 RD. The 1400k Italian audax we just got back from was done on the same size cassette. The fact is it works even though it's well over their specification. The missus used their cable RD and 40T and it's less good - it struggles in the highest gears, but her shifters are pretty meh so it could just be those and it's not like she's racing down hills. Anyway, I want Di2 on her bike and a smaller crankset and cassette on mine. None of this is any reason to go near SRAM.

Yeah, P2M's site mentioned something about them being normal q-factor compared to GRX.

Anyway, I've ordered a new Shimano BB and I'm going to stick my P2M gravel cranks on the Mason. Going from 34->30 means that I can stick on an 11-36T cassette for similar lowest gear to the 11-42T and slightly better jumps with a lighter and easier to pack wheel.
