This bike has now been stolen in London. :(

Lucky enough there's one for sale, absolute bargain at £935

Im fairly certain that I once stumbled upon a guy who not only reverse engineered it, he was making custom PCB-s that your own switches could be attached to instead of having to gut a shifter for it. But for the life of me I cant find his posts online, maybe he got hit with a C&D.

Edit: still couldnt find that one with the custom PCB, but how cool is this, from 10 years ago:

Josh Ogle from Ogle designs dug into this once, but I don't remember the exact outcome

I think this?

5390 euros, and its vinyl under clear coat?!

Shimano also found a way back in 2021 that could make it into production?

But jokes aside, the only things stopping me from doing this are that my gravel bike is 1x only, and Im still invested in rim-brake wheelsets for road/TT.

Damn. I like that very much. If/when my space chicken bites the dust ive got the replacement lined up, it looks like a really viable "jack of all trades" bike with 2 sets of wheels.

Normally I'd suspect that I overdone the bike too, but these watts/paces are not quite what they should have been on paper / what I could do in training. That bike split was 195W NP / 185W avg, with mid-Z1 average HR.

I started the bike with ~225W (Z2), and it took 10mins for HR to settle after the swim but it was all stable, low Z2 watts and matching HR. Then after an hour of this I just felt that lingering feeling that I might cramp up if I continue that pace. As for my normal running pace, in training I could consistently do 4:50/k off a bike session in Z2 hr, but the bike sessions were shorter of course. Thats why I dont think the pacing was the issue here, everything other than the cramps felt perfect, I didnt feel exhausted getting off the bike at all.

Im kinda torn if I should try to get in as much time as I can on the TT bike before challenge London and tweak the position, or do it on my road bike to see if same issue came up.

Just had a look at mine, they look like theyre in pretty good condition. But the upside of TRP is that you can buy a lot of bits and bobs for it, so I wouldn't worry too much about it!

Whats wrong with yours? The one that came on my vitus was in a very bad shape, but a proper rebuild sorted it out.

It is, but only the first time around. You can also buy chains that already have it removed to save you the faff. You can do it with several stages of different solvents, aid it with ultrasonic cleaner...etc.

Once your waxed chain gets dirty, you can wash it out in boiling hot water, dry it, then immersion wax again.

And as said, squirt can be used as topup.

Very. If there's any oil on your chain (or inside the rollers) wax/squirt wont stick to it. The difference is that with immersion you also ruin your batch of wax with a contaminated chain, here it just wont work well with the wax based lubricant.

Thank you for doing all this figuring out for me. Bought one of these as a complete bike on ebay because it was a steal, and building it up for my brother. The more Im looking at this frameset, the more I like it.

AFAIK, they dont sell the electronic component alone -which is the part that houses the ports wedging into the lever body, and the switches that go under the paddles. You can usually buy the top bracket as a whole, but they just end up being more than buying a complete shifter on the used market:

That is if you're 100% sure that the issue is with the actual microswitch thats inside that electronic bit. Maybe the rubber pointy bit (that touches against the paddle) on it just worn down a bit and needs something to fill back that spot. You can also buy bits & bobs for the paddles if the issue is on the paddle-side.

You can quite easily (and non destructively) take apart the paddle part of the shifter, and check if it reacts reliably if you push the microswitch by hand, not relying on the paddle mechanism.

If you dont want to go through all this, contact Pawel at Di2 gp, and if there isnt a solution, consider donating your bricked shifter for science :)

So, first middle distance in the bag from Ironman Warsaw 70.3. Puncturing your tubular rear disc 17 hours before start is not a great experience, 0/10, would not recommend. But we resolved it just in time to check in the bike to T1.

I dont have a good framework for comparison, but I would call the swim "choppy AF" and according to our supporters a handful of people had to be rescued out, and plenty gave up. With that in mind, I'll take my 46 minutes of fighting for survival disguised as swimming :D

3:30 for T1, not great but not bad.

Onto the bike. I've put a huge focus on electrolytes, micronutrients, and hydration for the past week (and on the day) to rule that out if I cramped up again on the bike. Which I did, about 1.5 hours in, just like last time on my 90k bike split in the relay. Its either a bikefit issue, or not enough strength work went into my training. Ended a bit windy bike split with 2:24:50 (for 86.5km).

4:35 for T2, including some stretching as I could foresee what was coming:

On the run. I dont wish anyone the feeling of changing into running shoes, run 50 meters, and then both your quads immediately cramping up, knowing you've got 21kms to go. Still managed to somehow nurse it home from there with a very-very slow 2:16:32.

Next up: Challenge London!

Great, set a reminder, thanks!

Now that you made up your mind:

-90% of the riding I do is structured training with intervals. I use the buttons on the shifters to lap my intervals, especially useful at shorter sprints. I have a Canyon integrated handlebar with outfront mount, and the lap button is in a very awkward spot

-I use a Garmin 520+. I hate the navigation on it. But, if Im navigating a course, that means im mostly riding in a group of 4-6 people, and I like that I can toggle between data and map without letting the bar go. Of course I know how to ride a bike, but its a nice to have.

-Battery level displayed on your head unit.

When will tickets be available for the one on the 27th?

So, bought some Camelbak podiums, lo and behold they rattle in all my cages. Three different one tested: Specialized rib cage II, Decathlon's Triban 500 bottle cage, and Elite Paron.

I should have read recent reviews of it. Would not recommend.

Finally made it to Caravel yesterday. Really really good food, and they've got another boat next to it with a bar (Bruno's).

with the different front and rear batteries specifically mentioned as one way of circumventing SRAM’s wireless and derailleur-mounted battery patents.

Really? Thats all it took? And Shimano could have done this all along?

From what I remember the comments were along the lines of "dont be surprised that the pedals wont have the same feel riding, and wont be as crisp to clip in-out". If it works for you, dont let me stop you! I'm just picky about it.

@gbj_tester thanks, appreciate it! Let me know if you found anything.

Where do you all buy your cleats for your assiomas? I cant find favero (xpedo?) or regular Look keo cleats at most places. They all end up being a place shipping from EU (despite .co.uk domain), and the usual suspects (sigma, wiggle..etc) only carry the keo grip version. Reading up on it its not advised to use that with assiomas.

So, red look keo cleats: love 'em or hate 'em, but where to easily find 'em?
