Re: Lightcarbon: New LCR017-D (or Yishun R1058-D)
I emailed LC last night regarding the super light version in size 56. They replied within 3 hours, which was a welcomed surprise. The sales rep was polite, detailed, and it was obvious she was well-informed. All the molds for each frame size are finished, however current production time for a size 56 is one month. I'm not sure whether or not LC and I will be collaborating as far as video content goes, but the price and initial customer service experience is enough to make me wanna purchase a frameset regardless.

Re: LTWOO ER9 & ERX - Electronic groepsets
Short review of the updated ERX version from ChinaCycling. So seemingly there’s absolutely no update on the cable port design on the derailleurs? That surprises me. I’m curious whether the waterproofing issues have been fixed. March 13, 2024, 12:00:09 AM |

Frame "inspiration" reference thread
There are a lot of open mold frames that... let's say "draw inspiration".... from big brand frames. The most obvious one is the SL7 and it's probably worth keeping a list of those with all their subtle differences, but I wanted to reference some others I've found and keep a thread going. Inspiration: Canyon Endurace  Open mold versions: Velobuild VB-R-066/OG EVKIN CF-025   Notes: Velobuild available in rim or disc brake config. I think the Velobuild version is a good bit lighter than OG EVKIN's. Inspiration: Cervelo R5  Open mold version: Tantan FM6x9 (609, 619, 629, 639)  Notes: the geometry is EXACTLY the same lmao. Also available in rim & disc versions as well as half vs fully internal cabling (I wanna say 639 = fully integrated). I know the TT-X38 is "inspired by" the newest Scott Foil but I'm too lazy to dig all those photos up. But you get the gist. If I had the time I'd start a website to capture all this open mold data. Finding info is a real pain in the ass March 25, 2024, 01:30:43 PM |

Re: Velobuild VB-R-218
That is not good. I've bought 4 frames from Chris but not that one. Strange clamping system, especially 4nm. Did you use a torque wrench? So I check inside the seat post and yeah they were two small cracks. I sent those pictures to Chris and we manage to get a new replacement frame. I'll put the current frame on my Kick Core and just use it for indoor training, I guess. April 12, 2024, 10:12:37 AM |

Lightcarbon build LCR015
Decided to build a backup bike for my wife. Rear brakes were a pain but everything else went together perfectly.

LTwoo rim brake / mechanical 2024 refresh
From LTwoo's 2024-25 catalogue, looks like all the rim brake levers will be refreshed to match the design of the hydraulic levers (with the Campagnolo-style thumb shifter than the older Shimano Sora-style thumb lever in the awkward spot). Mechanical derailleurs getting a refresh too - different graphics but hard to see what's changed mechanically.  R9 gets the holographic decal treatment  More minimal design continues down through the product line:  A slight graphical refresh on the gravel rear derailleurs but looks mostly the same  Still no sign of an electronic rim brake lever so Wheeltop likely to be the only Chinese player in that space for a little while unless Sensah springs a surprise.

Re: Velobuild VB-R-218
Got some new shoes for the purple bike. I asked the seller to ship without PCW branding but these are what showed up. I will likely remove the decals eventually.

Re: Velobuild VB-R-218
Conti’s premium tires are made in Germany. The GP5000 specifically says so on the tire I believe. The lower tier tires are from Asia. Vittoria used to be made in Italy but now they’re all from Thailand. Schwalbes are made in Asia as well I believe. Not sure about their top ranking tires. I’m not saying this is a bad thing in terms of quality. For me it’s rather about supporting my local economy, wages and working conditions and maybe for the stuff to have a slightly smaller carbon footprint.

Re: Airwolf: What is this model inspired from? [Trek Madone]
I just finished building my second slr from Airwolf (one for myself and one for a friend). Some experiences to share: Ordering the frame went quite smoothly, as well communications with Airwolf during the whole process: easy to get in touch with them and they're willing to help. Their statement that this is the original is obviously not true. Some small issues, especially with the small parts that come with the frame, indicate this is a copy. A good one though, as far as I can judge without testing it to and over its limits. Fair paint job, though it seems a bit easy to damage. We'll see. Please note that though the website states the frame is also suitable for mechanical shifting, it is not. Just like the original gen 7 Madone, it is only suitable for Di2 (or any other electronic shifting). The internal routing of a rear shifting cable has to go through too many sharp bends to let it shift smoothly. I spent a lot of time and trying several things to get it shifting without any issues, but in the end decided to strip the mechanical groupset and replace it by Di2. Learning the hard way... The second build-up was an easy job after that. Routing the brakehoses through the handlebar is really a pain. It took me quite some time and the help of an extra hand to get them through. I guess that'd be the same with an original; it's caused by the design. The parts that come with the seatpost are a bit sloppy. The wedge used to fixate it in the frame is way to smooth and therefore too slippery. Using carbon paste is explicitly discouraged. Ordering an original wedge (which has a roughed surface) solved it easily. The sadlle clamp was skewed and too wide (and heavy), and again using an original solved it. The headset bearings seem to fit well, but there's still some minor play in the headsets of both bikes after putting the bike together. In the second build I replaced the splitring on top of the upper bearings with an original one, but that didn't resolve the issue. My conclusion is it has to do with the first spacer. Adding an extra C ring on top as suggested above might solve it, not yet tried. The holes for mounting the front caliper were in the right place (both builds), but quite rough on the inside. The threading of the holes in the forks had to be cleaned out/threaded, otherwise the bolts needed far too much force to get them in. The mount for the rear caliper on one of the frames is not exactly even, so when I tighten the bolts the caliper will not stand exactly upright. This makes it almost impossible to adjust the caliper enough to let the disc run freely. Probably some paint issue. Solved by putting some thick nail polish on the frame on one edge of the bolt hole. Both bikes have been ridden for a few hundred km and it feels fast and sturdy. The handlebar is pretty flexible, which I didn't expect from a carbon one. But that may be me not being used to an aero bar. All in all I am quite positive about the Airwolf frame. If you go for this frame I'd advice to buy some original parts with it at the trek webshop right away: seatpost wedge and saddle clamp (together about 30€). But if you're thinking about building a very nice bike yourself, I'd certainly consider this frame. Today at 09:53:59 AM |
