BTW, I got an XT Di2 Right switch for 39.00 in the hopes of hacking it to the cat eye kit. But the mechanical parts use magnets over the epoxy/potted electrics to actuate the circuits. So I may put it out on an Aero bar instead.

I used to work in the PCB industry, selling and training operators for automatic optical inspection equipment for three different companies. I'm reasonably handy with a soldering iron, too.

The cheapest I am seeing the SW-R600 is like $80.00. Although there is a used one on eBay for 65.00 plus 10.00 shipping. ;)

PCBs

PCBs: Printed Circuit Boards or Poly Chlorinated Biphenyls?

Well, the glued on raised patch on the Di2/STi button sure improved tactile feel and shifting action, zero non shifts. I may put a bigger one on when this one falls off. ;)

I'm really warming up to that idea. If I added a pad that's 3/16" or so thick, that would create a very distinct feel between the buttons and sort of a stop for my finger if it starts to slide forward. It's certainly worth a shot.

BTW, I checked my ST-R785 levers and they only have a single port, so if I want to try the climbing shifter hack, I'd still have to buy a new junction box. Friggin' Shimano!

The climber wire plugs into a STi port. My glue on is 2mm thick FWIW.

Wait, one port! So you need a wire a port and the switch? Fuck Shimano on that one.

That's my feeling, too. There is only a single port that connects the lever to the junction box. There is a slot below it, but it's smaller than the wire port and it appears to be a dead end.

What A junction came with your setup?

I read the port is in there but not accessible due to master/cyl needing the space. Wonder if you could solder it in somehow?


Eighty something post cycling thread... Who'da thunk it? ;)

I've got the three-port junction box. so I'd have to get the one with five ports.

I took a look at the left lever again and there's an electronic module of some sort that the single Di2 wire plugs into. It's marked "07R MFA00A05" and it appears to have two ports, but the lower one is apparently plugged and it's partially blocked by the lever body. Is this perhaps the same module used in other levers? I'm not sure how any of this comes apart and I haven't seen any exploded diagrams of the lever, so I'm somewhat leery of getting into it.

If you happen to find any information from someone who's already hacked these levers, let me know. I'll keep looking, too.

And yes, it's really nice to talk about bike stuff for a change!

rotor has a 52t (!) rear ring for 1x13 shifting

More importantly, they're making 10-36t & 10-39t cassettes, which would be reasonable for use on road/gravel bikes and reduce the size of gearing jumps considerably compared to 10 or 11 speed cassettes. The system uses a 12-speed chain, too.

Given the redundancy of hating 11t cog on road bikes observed being stated here and elsewhere, how do we feel about the 10 for non road use?

I don't like it from a wear and smoothness standpoint, but with a small front chainring like 38 or 40, it works. Rotor is also going to make a 10-46 cassette so there are lots of options. I'd love to see an 11-36 or 12-36, which would work nicely with my 46/30 crank, but I doubt they have any plans to do either. Who knows, perhaps if 1x13 really becomes "a thing" they'll expand their offerings. At the prices that their current hydraulic system sells for, I don't see that happening.

I recently set up a new bike road disc brake bike for my wife using SRAM GX Eagle RD, shifter, 10-50 12-speed cassette, and a 36t 1x chainring on a Deore XT crank. She rides flat bars on the road, so the MTB shifter is perfectly suited. That setup gives her a top gear of 95 and a low of 19, which seems to suit her pretty well for the riding she does. After having ridden dual or triple chainring setups for the past 35 years, she was initially pretty suspicious about only having a single front chainring (thought I was somehow short-changing her), but she now admits to actually liking it.
