New frame: Longteng RD301-D
New forum member here, and starting a new thread after posting about this in a thread on the LightCarbon LCR017-D (https://chinertown.com/index.php/topic,4309.255.html). Long story short: I snuck in to the Taipei Bike Show today to check out some Longteng and LightCarbon frames, and at the Longteng booth, I found out that they have an unreleased frame which is undergoing testing: the RD301-D. Here is a short video that I took, and a few pages from their brochure with its geometry: https://imgur.com/a/XvH327j. Appearance wise, the 301 doesn't break any new ground, but a few things stand out: - It has an aero profile but is under 1000g weight - The geometry (especially stack) sort of sits between an upright endurance bike and bikes like the Velobuild 177 and 268, Winspace SLC 2.0 and 1500, Yoeleo R11 - this geometry is a sweet spot for me [edit: the geometry seems comparable to the touted all-arounder Trigon AR01] - Whoa, max tire clearance of 38! - Cool little storage space on the downtube - Threaded T47 BB - Per their rep Alisa, it's made with a mix of T800 and T1000 carbon This frame hasn't been posted on their website, and Alisa said it will be released "in a few months" once testing is complete. The 54cm has passed their tests and is available if anyone is interested - you can email Alisa at longtengalisa@163.com. Peace out!

I built 2 268. SMR. Having built 9 such chinese bikes, i'm yet to see the ACR system on any of them. I would get Alisa to confirm though. September 18, 2024, 05:12:30 AM |

Re: New frame: Longteng RD301-D
I plan to buy the RD301 too. So far contact with Alisa has been great and she is very helpful. Here are some of the photos of their show bike (size 52). Nothing special but it's cool to see how the fully asembled frame looks like. I think it looks really good! Another interesting thing that I found... On one of the photos, you can see (top right) the frame from Ribble? I did not know, that they are producing frames for Ribble, I've only heard about Argon. September 20, 2024, 04:46:48 PM |

Update.... Alisa replied she will sent out the seatpost wedge and rubber cover too. I think they "acknowledged" the slip up and making it right this time... October 08, 2024, 10:39:23 AM |

Re: New frame: Longteng RD301-D
I am interested in this frame, but have sent two inquiries through the website and gotten zero replies. What is the best way to get a price quote on one of these frames? Never use the contact form of the website. I tried that with different manufacturers and it never worked, even if the website would say "message sent" or something  most have mail adresses or QQ or Skype contacts somewhere on their website.

Re: New frame: Longteng RD301-D
Still waiting for my missing seatpost wedge parts to shown up, been over 3 weeks since Alisa has send it out... I did get mine. When I tracked delivery of the package, the first one got stopped by CN customs, so Alisa sent another one. Somehow, now I have both packages lol, so maybe check the tracking. I ended up getting delivery in about 3 weeks after all that. Btw they do have a saddle clamp for oval carbon rails. But you can also find oval adapters on Aliexpress - the saddle clamp is the same as what I believe is the Ritchey one-bolt clamp, and those can be found in several different sizes on Aliexpress. Now I can finally build the bike, yessssss! October 26, 2024, 12:36:54 AM |

Re: New frame: Longteng RD301-D
Here it is, at last! I picked up the bike last night from the LBS and spoke to the mechanic who built it up. His take: - Overall, it was easy to build - No major issues, nothing was mis-aligned, BB fit was perfect - Frame quality seems to be good with clean internals - It didn’t feel all that different from building up major brand bikes A few other notes: - The bike was built with Ultegra 8170 Di2 groupset, Elitewheels Edge Ultralight 45s, Kocevlo integrated bars, GP5000 tires, RideNow TPU tubes - Measured weight: 7.4 kg without pedals (7.65 kg with pedals) – I didn’t go full weight weenie, so there’s probably still room to take that down, but it’s not a priority for me - I put on 32s and you can see from the pics that there’s plenty of tire clearance, probably room for more than the stated max clearance of 38 - The downtube internal storage is a bit finicky to close – there’s not a solid click to close, and I need to be careful to get everything aligned to close it, otherwise it comes off pretty easily. Once it’s closed correctly, it feels solid. I’ll have to take it for a few rides to see if it’s problematic - This is one of those frames with a soft top tube where you can press it down with your thumb – the mechanic said that it’s no different from some of the other lightweight frames that he has built, but you shouldn’t sit on the top tube at the stop light or tryna look cool - The mechanic pointed out that there is a bit of play in the rear wheel – if you push on the wheel from the side, you can feel a bit of looseness; he tightened up everything but it’s still there, he said it’s probably something internal to the hub, it shouldn’t impact the ride, but I’m going to follow up with Elitewheels on this - I took it for a short spin last night to bed the brakes and there was no seat tube slippage, although it was only a 30 minute spin over smooth surfaces. (I did end up with a flat… I’m not very heavy and rarely flat, I think I’ve flatted maybe 3 times over 15 years, so I guess it’s Mazel Tov!) The weather here has been crap (typhoon just came through, another incoming), so I may not be able to ride much on the new steed. Once I do, I’ll come back with some initial ride impressions (and au naturel pics). Cheers. November 04, 2024, 07:36:10 PM |

Re: New frame: Longteng RD301-D
Nice build, I am becoming more and more interested in this as an all-purpose bike! I don’t have calipers for exact measurements but hopefully these pics will help. The rim internal width is 22, and it looks like the 32s are 32 when inflated. There’s been a bunch of content recently from folks like Nero on “all road” bikes like the Enve Melee and Ribble Allroad, which is interesting because I think this frame fits in that category: not an aggressive racing geometry, but not upright like endurance bikes - it sits in the middle where comfort and speed intersect. With a bit of room for rough pavement / light gravel. That’s exactly what I’m looking for, let’s see how this thing actually rides when the weather cooperates. November 05, 2024, 02:19:18 AM |
