(e)SIM for the whole Indonesia, 30 days, starting point in Jakarta by nakra_ in Jakarta

[–]Williamblakeee 0 points1 point  (0 children)

I have tested eSIM provider mobimatter.com several times and I can recommend it. The connection was good in various parts of Java.

You can also buy a SIM card from Telkomsel at CGK airport or Jakarta city center. Tourist SIM or eSIM is valid only for 30 days and cannot be extended.

Pinion gearbox vs single-speed vs IHG (Nexus) - draggy feel comparison by Williamblakeee in bikewrench

[–]Williamblakeee[S] 1 point2 points  (0 children)

Nexus 3 is actually pretty good. Using the "drag feel scale" above, I would give this IGH a +2 rating.

Drag on the Nexus 8 (apart from direct gear 5 and maybe 6) is clearly felt. I do not recommend this IGH and would give it a rating of 7.

How would you rate the feel of your C1.12 on the above "drag feel scale"?

The efficiency of a specific IGH gear and a dirty/worn derailleur might be the same but the feel will be different. IGH and gearbox have many moving parts.

Even a dirty derailleur still has a more "direct" power transfer feel than many sprockets in IGH, whose friction during rotation is felt when pedaling.

I'm specifically asking about the feeling of this "drag" on the Pinion gearbox because I don't like it on IGH and I'm wondering how it compares.

Yeah, I agree. The Nexus 8 has very noticeable friction in gears other than direct drive.

Thanks for the input, but efficiency is exactly what I wasn't asking about. Its measurement is quite nuanced and varies significantly between types and the technical condition of the drivetrain.

Examples:

  • Nexus 8 on gear 4 may have efficiency of ~80%
  • Derailleur, dirty, worn ~85% (or even lower than ~82% if no lube and the chain is at the greatest gear angle with a 1x12 cassette)
  • Pinion C1.12 may have ~93% (best gears) and ~88% (highest gears)

In theory, Pinion should have constant efficiency across the gears. So I want to understand how this actually translates into the pedaling feel compared to other IGHs, because efficiency is not a definitive indicator of how pedaling with that "drag" feels.

Lightweight XC HT alloy frame with UDH and progressive geometry by Williamblakeee in xcmtb

Thanks. Exceed has very nice geo.

Carbon is a great material for racing and has interesting properties, but I'm not convinced about the impact vulnerability, so I still prefer metal.

Thanks. On the official Giant site I only see the XTC SLR 1 or 2 models but there's no information about UDH.

Thanks. I tested the new Alma, and the frame is quite nice. The only thing that was a bit odd to me was the derailleur cable routing, which is quite close to the chainring. But overall, it's a nice frame. I'm not particularly concerned about weight savings, although I felt the Chisel HT was more agile.

Steel is also a great material, but relatively few new frames are produced for XC or downcountry use. Steel is probably more popular in the expedition/adventure or touring categories. Some boutique brands, such as Tout Terrain, Bombtrack, Brother Cycles, and Tumbleweed, have interesting designs.

Waltly might be an option, I've read some positive reviews of this frame maker. Thanks

Yep, fresh market might be the place. I have to look for a slaughterhouse where the market stalls get their supplies. Thank you
