Re: LTWOO ER9 & ERX - Electronic groepsets
LTwoo calipers are bricks. I'd rather source some Shimano calipers if possible or use lightweight ZRace/IIIPro calipers. I've tried this, just wanted to warn that they aren't super great IME. I'd source shimano calipers instead. December 06, 2023, 11:17:18 AM |

Re: Chinese cycling clothes
Just wanted to check back in after riding my Swiftofo "triathlon suit" with "Italy Miti" pad: It's alright. It checks the basic boxes of what I was looking for: pockets, decent pad, ribbed/aero textile. The pad, as I suspected (and hoped), is not a triathlon pad but a proper road pad. The only knock I'll give it is the neck is just a bit too loose, when I really tuck it starts to crease/lose tension a bit. Everything else about fit on my suit is pretty much dead-on so I just think the design needs adjustment. Value for money I would say is 4/5. January 21, 2024, 10:59:25 PM |

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
Just got a pair of Stone 110R2 chainrings delivered. These are the absolute-black style rings that are milled out on the outboard side. Really nice rings imo. They look shiny and tumbled to me. Favorite feature is that the female threads for the chainring bolts are integrated into the inner ring, not sure why (it’s not like there’s a clear advantage, maybe weight savings?) but it feels extra premium and lightweight.

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
Good to hear, also awaiting them in 46-32T configuration. Will combine them with a Magene P505 PES base crank to replace a 46-30T GRX600 set on my Gravelbike. I also bought the same configuration. Be prepared to remove your crankset, I had to remove mine to get the inner ring behind the power meter, since the inner diameter of the ring and the outer diameter of the power meter are so close in size.

Re: ISO (San Jose, CA) mechanics knowhow working on chinese frame/components/parts?
Again I'm just looking for a Chinese friendly local mechanic(s). Not interested in investing time/skills/tools/money into wrenching modern bike. I gotta say this attitude and chiner bikes aren't a good mix IMO February 16, 2024, 10:42:32 PM |

Re: Seka Exceed RDC Broken Frames: Source of Concern?
USA Seka (non RDC) owner here. I had a warranty issue and it was processed pretty well all things considered—I can vouch for the after sales service. Fantastic frame, it’s been very nice. If you can get a hold of one at a decent price I’d say it’s worth it. I think the Tavelo is pretty much the same spec frame though, I’d also consider that one in today’s market.

Re: Goldix 21-spoke 2:1 spoke ratio disc hubs
I’m definitely a bigger guy and can put some power down. 80kg and 300w+ FTP when well-trained. I hear you on the fact that torque transmits through the whole hub. My reasoning is that the hub experiences significant twisting/deflection under pedal load (at least according to Peak Torque), so if the goal is to maximize efficiency, it would make the most sense to make the torque transmission to the rim depend on the shortest load path as much as possible, and that would be through the drive side spokes. Now all this is in my head and not real life which is why I’m asking on here. Rear braking is a concern. Given that the disc side spokes are radial this means the bulk of the rear braking torque will be transmitted through the hub shell and up the drive side spokes. I think the main reason I don’t see it as problematic as the reverse case is that with pedaling I’m trying to maximize efficiency, something that doesn’t matter with braking. But I am concerned if something about this arrangement is exceptionally stressful for the rim. February 22, 2024, 08:48:07 AM |

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D)
Finally catching up to this thread. Between this bike and other new bikes (like the TFSA options), I gotta say chinertown has really been spoiled with low-cost low-weight semi-aero bike options lately.

Re: Racework is peddling $hit.
What did you return? I had bought a chain but they sent me a chainring. I'm guessing they had me return to the US hub but they didn't send me a prepaid label. The app told me to pay for shipping, enter a tracking number, and promised that I would get a chance to submit my receipt and get the return shipping cost refunded. I did as I was told and was never given an opportunity to enter my return shipping fee. So I ended up getting a refund on the item but I also ate the $10+ cost on return shipping. Super disappointed by this experience. March 03, 2024, 01:37:49 PM |

Re: Best and worst overall quality/value components/tools/gear from AliExpress?
I don't touch any mixed alloy/steel cassettes. Especially if a cyclist does a bit of climbing, those big alloy cogs will wear quickly. Just to make note Goldix and Ztto have the same design all-steel lightweight cassettes. Goldix just sells them only in black. I believe Ztto sells them in multi-color. I beg to differ, I have a whole season CX on a goldix XDR cassette with an aluminum low-end cog, lots of climbing in abrasive conditions, and the black anodization is hardly worn. The reality is that with these larger cassettes that have prevailed in the last years, the wear is distributed over so many teeth, that the problem that the lowest cog wears too quickly is no longer a major issue.
