Hulsroy's Hustle

Incredible. You better start doing youtube videos on all of this stuff.

Inheritance Machining Denmark style

Thanks for making great stuff. ♥️

Thanks man ❤️

I am dreaming about TRP Hylex with custom momentary buttons on the levers rather than the usual climber buttons "integration".

Anybody on here care to give me a bit of advice on what to get hold of and read up on to make this work? I have a very capable friend I share a workshop with but I want to understand what I need before asking him to help.

I'd like a 1x drivetrain with an 11sp di2 mech shifting up using a button on the right lever and down using a button on the left lever. Is this daft?

Maybe this

I achieved something similar on my Cervelo S2, which has subsequently been transferred over to my P5, but getting a climbing switch, stripping it down to the bare PCB, soldering some flying leads onto the PCB contacts underneath the switches in the climbing switch (or rather getting a friend who's much better at soldering than I am to do it) and then connecting the flying leads to momentary switches originally intended to work as remote switches for Cateye cycle computers.

There were some photos of the process on my Cervelo S2 'Dentist's Chair' thread, but they're no longer visible as the web host looking after the pictures doesn't seem to allow https. It's all pretty obvious once you strip down the climbing shifters though.

The only hard bit is finding switches that won't look like massive carbuncles when they're in place.

Haha, sorry. As long as they're all for a good cause, I'll allow it. I get ansty if my tabs enter double figures. Most of them are LFGSS so a different use case.

It sounds like any momentary switch can be repurposed. Finding one that isn't too colossal, mounts nicely, etc, is problem one (the one you picture is quite deep, has big lugs for solder, etc. check the mechanical drawing).

The bigger issue is that it sounds like climbing shifters have to be plugged into DI2 shifter units, as satellites? You can't just have them on their own? I am not sure on this, DI2 is a complete mystery at times, and what you can/cannot do seems wildly variable. But you might not be able to have just satellites.

This is correct. That's why you need to use the guts of a climbing switch.

Ok, so its the kids birthday today. But what you guys are saying is what I found out as well I think. Rear mech is "dumb" and switches are "dumb" so I need a junction box and climbers switches. Right?

First, find a neat way to mount momentary buttons to TRP Hylex levers then buy this thing and use PCB from shifter and solder my buttons of choice onto PCB with longer wires and find a place to keep the PCB safe and dry. Sound easy enough...

Now the question is: can I do it cheaper?

Did you rule out the addon buttons made by TRP themselves?

(not very elegant, I admit)

Yeah they do not make me happy

Soooo my mate had a very nice button and we are thinking about mounting it like so:

That would be very neat.
Does it fit above the bolt for reach adjustment ?

Yup. Only worry is whether the cables and little pins will last over time as the lever moves when squeezed

You could coil it like a telephone cable?

I can coil you like a telephone cable!

Holy shit what a haul

any reason to not use etap axs with wireless blips?
or do you already have the di2 bits?

I've been toying with the idea as it seems like an easy way to add gears to my charge plug which has trp hylex brakes, without changing the levers or adding additional cables.

Theres zero affordable etap stuff available to me - new or second hand.
Where as 11sp di2 is pretty easily available to me. And everything else I own is 11sp mechanical road. Nice be able to swap out wheels etc.

I would love to try a SRAM etap groupset. But I don't have any affiliation with sram yet and even at trade it's a very expensive thing for me to purchase.

But also I think it is very on brand for Hulsroy Cycles to be tinkering and hacking the systems. . TRP Hylex might not be very pretty levers but they are extremely comfortable to me.

yeah cool. just chucking an idea into the mix!
from the very limited research i've done, an etap rear mech should be compatible with shimano cassettes as long as the speeds are the same - not sure if it's possible to hack / change the speeds of the mech?
so in theory all that's required to change a compatible ss bike to etap would be a chain, rear mech, and the blips.

the other thing i'd looked at was something like this external device which converts a mechanical mech to wireless electric, but looks pretty janky. i think it's based on the x-shifter that was on kickstarter a few years ago.

one thought around buttons: waterproofing. small tact buttons like that take up very little space but it won't take much moisture in there to get a short. The wiring isn't too hard to cover up with heatshrink etc, but the actual switch itself is effectively open to the air. rain, sweat, dew, etc.

Have you considered Archer components Dx1? Comes up cheap on eBay from time to time.

I have not but does not do what I want

I guess that is true. I will have a think about how to solve that. This bike is for nice weather only though
