I've installed a few of those tubolitos for customers. The valve tube (that the core screws into) is plastic, and deforms easily. They start leaking after a few rides usually. Teflon tape helps, but it's kind of the nature of the product.

I had one that the thread rounded out and I couldn't keep the valve tight. Tubolito sent me a replacement and on the faulty one I epoxied in the vave stem and all is fine now.

Tubolito contacted me and sent a pair of replacement tubes, great service 👍 Berk has sent a warranty Lupina too, this time in 3K (because lighter) and oval rails, so kudos to Jure and his team 🍻

Meanwhile, I put the new J&L hollow Ti rotor bolts and weighed my 140mm KCNC Razor, which turned out 3g lighter than in spreadsheet - a freebie! And a heavy butyl tube I run in front as spare.

This is a great build and some good ideas for my 1x build.

Yesterday, I finally got to unpack my bikes after moving to a new city. Inspired by @Godzuki, I replaced the bolt in Darimo Sub4 with hollow J&L Ti bolt, which saved ~0.7g. Anyone knows where to source hollow Ti bolts compatible with T1 clamps? These should have a rounded yoke contact point, not flat.

That Berk saddle is beautiful! I need to try one. Do you know if he paints his parts? It would need to be white for my bike.

You can order a white leather saddle, like some WW members, but I have no idea about painted carbon shell, I'd ask Berk about that.

Tubolito has warranted both of my failed S-Tubo Road, the new tubes are ~1g lighter and did not lose pressure overnight like last time.

This Saturday I decided to put a fresh ARO-09 rotor on just in case to see if it would rub less, I think something in my setup causes rotor rub, a lazy piston or non-faced mounts. Anyway, I went for a ride next day and on the way back something pinged and flew from under the front wheel. "Probably a pebble", I thought. At the next "downhill" - it's pretty flat in SpB, so after a while - I noticed that left lever goes all the way to the bar! The rear brake was barely enough to stop in time before I hit the traffic. I forgot to tighten the pads pin during adjustments and lost both pads and pin. Now I have to grind down another set of Cooma EX pads down and order another set of TP pins. What streak of bad luck, I already had three parts warranted this year. I need to make a checklist for after the service.

On the subject, anyone knows where to find M5 pad pins in aluminium? All I can find is Shimano M4.

If anyone's interested, here's how -12deg 110mm Hyperstem compares to -12deg 110mm IX2. The Hyperstem was traced from this document, then extended 1cm, all measurements match chart from here. To match bar position, IX2 should be ~5mm lower. In this configuration, IX2 will be ~3mm taller than Hyperstem, so probably no need for a top spacer.
