What BB are you guys getting for this frameset?

I didnt get confirmation from Tantan/Seraph, but presumably it is also a T47A with a shell of around 79mm. I'm personally looking at the Kactus T47A on aliexpress, but interested in other options 

I had the Kactus T47A but the "ceramic" bearings started to make funny noises after about 800 km. I pressed them out and pressed in genuine enduro bearings and all is fine.

Put cliks on both of my bikes. Honestly the simplicity of just clicking the pump head on and pumping vs the 5sec it takes to inscrew the presta...its so dumb but so satisfying haha

I can confirm. Simple and satisfying. No more bending of the inner cores by my wife. No more paranoia if the presta is screwed in properly and will not leak slowly. One of the best ways to spend 4 euro in the cycling hobby imo.

Does anyone know what's the tire clearance of v2 in the back compared to v1?

I have 30mm tires that inflate to 32 mm and it's extremely tight for the rear wheel.

Because theu already produced the Darimo one for the SL8 and it is very light. So they don't want to develop the Black Inc V2.

That's a strange decision on their end, but it is what it is.

One other point worth noting: Polar and RK Ultra—also trading under the names Mirror Carbon Fibre and First Class—are actually sourcing their frames from the same place.

Do we have a proof of this?

Also, does anyone know why this v2 seems to come with Darimo handlebars instead of Black Inc?

Yeah, I typically stick to the 60s on the rear rim, but I wanted to try out a firm feel and it was fun while it lasted. I kinda got why some people like narrow tires at high preassure. I felt like a speed demon

So I am curious here, and yes, I know there are "tests" about that all over the internet, but - were you really a speed demon, or did you just feel like it?

also, is it really that much better in real life........ Nope.

K3 has significantly better battery life (+50%) and screen than K2 (Source: I have both sitting in front of me).

Your earlier comment regarding readability is perplexing too. I run K2 at 50% and I never had a difficulty reading it, even in the brightest Mallorca sun.

I recommend Karoo 3. I am very happy with Karoo 2, and now after several years with Garmin, my wife switched to Karoo 3.

Pros:
- very customizable, including all screens, climb pro, lap screen or workout screen. You can also fully customize appearance of maps via xml file (e.g. I significantly increased contrast, distinguished paved/unpaved surfaces, and added drinking water/toilet/atm icons)
- very good and clear display, and modern UI
- can handle power meters, di2/etap shifting (I am not sure about er9 though, but I guess?), radars (including chinese brands)
- never any issues with syncing routes/rides; the ride automatically uploads to strava/invervals before I take my shoes off. On the contrary, syncing rides/courses used to be a repeated issue for my wife's Garmin, prompting several reinstalls.
- you can sync/send route from a link or gpx file using your phone. You long-press the link and "share it" via the Karoo app and it just sends it to your account and Karoo. Very simple and super handy when bikepacking trips goes wrong and you have to conjure a route on your phone while standing at a train station and somehow load it into your computer
- you can load any android app onto it, including spotify
- receives actual updates every 2 weeks

Cons:
- 12-15 hours of battery which can be an issue for some
- the top drawer (like on your phone) is a bit laggy of Karoo 2 but much much better on Karoo 3

Here it can be usually/often bought for 300 euro, but I understand it may be outside of what you are willing to spend on this. Love the device and fully recommend, though.

The value proposition is just not there for me. You are a guy on the internet without any authority. Your alleged insider contact is just that - alleged insider with zero credibility.

My impression is that fulfilling all the aims that you suggested is way above the price point in your original post. You may get a CT scan for $200, but who will do the data analysis? Do you have a background in material science? Can you even use CT to determine fibre type/brand (I kinda doubt that)?

For me, the quality/composition of a single frame is not a question. But how consistent is the manufacturing/quality process? And you need many more frames to figure that out.

P505 already had temperature compensation

Quote from: toxin on May 15, 2025, 10:05:25 AM
Agree. No desire to replace my p505, but improved battery life, weight and accuracy are good iterations. I also think they've made the back of it a little lower profile as the incompatibility warning for BB386 and T47I is gone and replaced with

Ah yes, that's great news. I was looking for this info but couldn't see it anywhere.

I probably phrased my original post poorly - I did not mean to suggest that I was disappointes. I was just wondering what's different in the new version.

So what are the improvements? It looks a bit lighter (~25g or so) and accuracy change from 1.5 to 1%? Am I missing something?

Quote from: Serge_K on May 09, 2025, 02:46:51 AM
Almost guaranteed to wear out faster, will not perform better, so it's purely a weight weenie thing. Will probably theoretically save 1 second over a 10km climb.

Tbh I never have and never will understand this obsession with weight. Sure I will try to make sure my bike is not 12 kg. But when people start doing ridiculous things to save 100-200g when 1 kg on 7% saves you like 3-4W...

In one of the YT videos that I watched (don't remember which one it was), they said $800 without chainrings.
