Re: Velobuild VB-R-177
Well, this was a shock. My frame got shipped on the 13th and this morning has been delivered to my house in the UK so 3 days shipping and no import charges! It was using EMS HK. Obviously the first thing to do was to weigh everything. It's a size 54 - M clear coat paint. Frame (with derailleur hanger, FD mount, bottle cage screws, seat post clamp, grommets) = 1039g Fork uncut = 384g Seat post with all fittings = 211g Handlebar (400 width, stem 100) = 311g Everything looks very neat and tidy - can't wait to put it all together.

Re: Elite Wheels ENT vs Elite Wheels SLT vs Velobuild VB-RC
I waited 10 days for the production and then shipping ended up being by DHL to Montreal so I received my wheels in less then 3 weeks, Wow that's great to know! I'm in Quebec also, hopefully the same happens to me. Thanks August 20, 2021, 12:58:57 PM |

Re: Velobuild VB-R-168 Frame
Hi all! I have been lurking this thread for the past few months while deciding if I should go ahead with building my own bike, and whether to get it from Velobuild. Really helpful tips so far and definitely helped with my decision to make the purchase! I finally decided order a VB-R-168 from Chris, in Matte Chameleon Green colour. I thought it would be useful to share my experience and two-cents on the bike building process. It was one rewarding experience to finally be out riding on your self-build bike! Size: 52 Groupset: Ultegra R8000 Hydraulic Disc: RT800 140mm Front and Rear Handlebar: 400mm/90mm Wheelset: From Taobao 60mm Depth with Hubsmith hubs Tires: GP5000 TL Saddle: AliExpress power saddle lookalike Pedals: AliExpress Lollipop pedals Weight: 8.2+Kg there about The building of the bike was not too difficult, just gotta do research and watch youtube for bike building process, tips and tricks, note the torque settings of the various components. The most tedious of all would be the internal routing. I routed the cables through the handlebars first, followed by the rest of the routing through the frame. Used an old brake wire to help with the guiding of cables through the respective cable holes. The FD cable stop was some what tricky, I had to file off the edges to get the cable to fit in to the hole. There is a small bracket to secure the FD cable stop into, it is rather flimsy and mine broke off. I had to fit it back into the frame from the bottom bracket hole, and screw the cable stop into the bracket. (sorry i didnt have pictures to explain it better). Another problem I had was that the headset compression ring not being able to sit squarely into the bearing, I had to squeeze the compression ring inwards a little (with a lil force) for it to sit properly into the bearing. Otherwise there would be large gap between the headset spacer and frame. Otherwise, rest of the installation was rather smooth! This is my first full carbon bike with deep wheels, so I cant exactly do any comparison. In general the bike rides really well, with much better handling, and maintains speed better. Overall very happy with the whole build! October 18, 2021, 09:10:54 AM |

Re: Velobuild VB-R-168 Frame
Could you elaborate on what you mean here? Because at first (and second) glance this doesn't seem to make sense to me. Lateral stiffness is important because during a sprint, the wheels are no longer constantly vertical. So the force pushing the wheels can cause flex if the wheels aren't stiff laterally enough. Imagine a wheel angled at 45 degrees, and the force from the cyclist pushing that wheel straight downward at 90 degrees. April 27, 2022, 05:43:37 PM |

Re: Advice on fake frames
The S-works SL7 frames are TFSA Jh-33 frames painted..I think you have to look closer, they're copy's but they're not the same like they just paint them... January 16, 2023, 09:31:55 AM |

Deng Fu R13
Hi everyone. Longtime lurker, first time poster. I've learned a lot from the forum over the years so it's time to give back by sharing some knowledge. The first frame that I ordered directly from a Chinese manufacturer was a Hongfu FM069 in 2014. It felt a bit more like gambling then. Fewer people doing this, less knowledge about the producers, and not knowing anything about how customs would work. I was out of the game for some time because that frame lasted until spring 2022. The only trouble I had with it was due to a small design flaw. Shimano changed the front derailleur when they came out with Ultegra 6800 and the arm of the derailleur pressed on the frame, but like I wrote, it lasted for years and thousands of KM, until last spring. I noticed what looked like a slight crack on the top tube while sitting at a cafe after riding. It felt a little soft when I pushed on it, but I couldn't tell how bad it was. I road it a few more times and pushed on it, and pulled on it with my fingernail, etc. I eventually decided that I wasn't going to feel safe riding it at speed on the open road, so I dissected it the best I could around the crack. Long story short, I'm convinced that it is next to impossible to properly inspect a carbon frame without professional tools. Full stop. Sure there are visually obvious flaws, but we won't catch anything internal. The other side is just as true. I'm happy I retired that frame, but I'm not 100% that is was necessary. So I decided to order a new frame and use my existing grupo and wheels. It was spring and I needed a frame asap so I panic ordered a Rinasclta 2020 light weight rim brake road frame. They were professional, I got the frame relatively quickly, even with a custom paint job. It rides nicely and generally does what a frame should do: let you focus on riding. I had a little problem with the rear derailleur hanger. It was misaligned and there is so little carbon where it screws to the frame that I'm afraid to use a derailleur hanger adjustment tool to bend it into place. I made a shim out of thin plastic and that got it close enough that it shifts without problems. I can share photos or a tutorial if anyone has questions about what I did. I'm happy with that bike and it is now on my indoor trainer and I use it as my winter bike. I was ready to take a big step forward after putting in the training time the last few years so this autumn I started looking for a new frame to build up from scratch. My priorities were integrated cables, disc brakes, and somewhere on the aero spectrum of frames. After much lurking on the forums, I finally settled on a Deng Fu R12. The Yeoleo R12 (completely different from the Deng Fu R12) did work with me for geometry and taste. A few final contenders had BB86 bottom brackets, which don't play nicely with sram dub cranks. So the Deng Fu R12 with its BB386 was the call. Mia was helpful and answered my questions promptly. The price was nice. Everything was good until I changed my mind about the size. I wanted at 56cm frame instead of 58cm. The 56cm frame was out of stock. I was disappointed because I was ready to pull the trigger, but she got back to me to let me know that they had the new R13 in 56cm. She said it was very close to the R12, sent me a photo, but didn't have a geometry chart to share. I decided to order it anyway. It came about a month later. Mia shared a tracking number when it shipped and it arrived very well packaged in my country without incident. I tried to look at the inside of the frame the best I could without a proper insertable camera. Everything checked out. The only thing that I noticed was some latex leftover from the molding process. I built it up with sram force. The brake cable routing was easy; I didn't need anything other than tape and the plastic tubing that came pre-inserted in the frame. I'm not 100% happy with how the headset spacers are fitting into the integrated bar/stem. The spaces have a little dot that fits into a corresponding hole in the spacer above and then the stem. The space match up perfectly, but the carbon stem is tightened around the steerer tube, which changes its diameter, making this last interface slightly misaligned. It's about 99% there, just not perfect. Certainly not a safety issue. I have zero other comments other than it was easy to build. I used a Token thread together ninja bb. Besides having to find their tool in stock to buy, it was easy and tolerances checked out the best I could tell with calipers. The other part of the project was building wheels.

The only difference that I can see between the R12 photos I've seen online and my R13 is in the seat stays. The R12 has slightly flared seat stays that are separate when they leave the seat tube. The seat stays on the R13 come off of the seat stay as a single, joined piece that then separates to each side. The other part of the project was building wheels. I bought rims from Light Carbon (https://www.lightcarbon.com/super-aero-undulating-rim-depth-700c-disc-brake-carbon-clincher-rims_p207.html). Super easy to deal with. Prompt emails. Answered questions. Shipped with a tracking number and I'm completely satisfied and enjoyed building the wheels. Last, I used a matte 2k clear coat on the frame and semigloss on the rims. I had more elaborate painting plans, but not a place to warm and dry to realize them in the winter. January 19, 2023, 09:38:30 AM |
