    Chinese Carbon Thread and Ebay direct version 7.0

    Time to roll out a new thread, as 6.0 is getting a bit unwieldy. Remember please, no counterfeits.

    Not sure if I should make an entirely new thread for this question or not, sorry if I'm posting in the wrong place, but here goes:

    I'm looking for a non-branded/Chinese TT frame that I'll be building with a Chorus mechanical group... Not super picky as far as looks/aero features or price, just something generally time trialish. Here's the tricky part, I would need at a minimum a size 58.

    If anyone knows a few sellers to direct me to it would be hugely appreciated. The bit of browsing I did on eBay didn't have anything my size.

    Thanks!

    Ha well the R-002 (R-022) I received is pretty useless to me. Zhongwei sent it with out installing the front derailleur hanger. The frame hasnt even been drilled for the hanger. Pretty surprised, my last frame I received from them is pretty awesome. Now I will be interested to see how they handle this.

    Just wondering if anyone has seen this with the carbon chinese bars. I have had good luck with a few sets but this last pair I got I am kind of annoyed by. I was mounting the stem on the bars with a Ritchey 5Nm torque wrench and carbon paste while I noticed this on the back side of the bars.....







    I took a needle and it poked the spot to find its only the clear coat that bubbled so I sanded the spot and put on a coating of clear coat nail polish. It looks normal now and nothing seems to be cracked. Did the coin test and sounds strong. No sounds came from the bars other then the grit making its normal sound from the carbon paste.

    Im just not sure what to make of it. Its not directly on a spot that is clamped but there was definitely a raise in the clear coat or bubble. I guess the question is do I ride with them or toss them.... I stopped by my friends shop and he said it was an air bubble as well but he only got to see it after I sanded and re coated it. Other then the pictures I showed in the thread that I sent via text.

    Does it look like this? If so, that's how it's sold. Mine came like that. It's made to be used with front derailleur mounting clamp.

    Trying to gleam some knowledge from others who have more experience with this than I do. I got a chinese CX frame, and after sawing down the steerer tube, I noticed that the inside of the tube isn't the same material as the outside. I suspect that this is fiberglass. Am I in significant danger of breaking my face with this fork?

    That looks normal, the inside of any carbon fiber is going to look gross and nasty looking. If you cut a frame in half you would see the inside doesnt look anything like what we picture carbon to be. Cheaper carbon is more resin then fiber and it can be a bit more flexible under some conditions but that steer tube looks fine and thick!

    Hi All,

    Lots of information in this thread(s)! I am considering building a Chinese carbon fiber road bike. I have a Domane 2.3 that I ride quite a bit and I would like something a little snappier on the road. I built a Dengfu FM190 Fatbike (25.5 lbs!) that I am incredibly happy with. I was just curious if there is a cross reference sheet out there on what frame models correspond to their name brand frames, for example the FM098 looks a lot like a Venge! Im not certain which model I want to go with yet, 6'4" 180lbs, I ride a 60CM Domane, all my mountain bikes are XLs or 21".

    Any and all advice is greatly appreciated!

    Here is the FM190!

    I don't think he's referring to the inner surface but to the inner 1/3 of the steer tube wall. It almost looks like it has an aluminum sleeve inside the carbon exterior tube.

    Thats not aluminum at all, cut it in half and you will see. There is always dust and gray powder left over from resin and carbon. Steer tubes are thick as heck so there is many layers of both used. I still say its fine but if he is unsure Id stop by a local bike shop and ask what they think of it.

    Hi everyone. It's been a while since I've asked anything on here, but I have a question. Does anyone know of a manufacturer and frame number (i.e. FM***, R***, etc) for a frame the same or very similar to the new Trek Madone 7 series? This being the aero frame/forks with KVF tube shape.
    Thanks in advance.

    A cross reference sheet is a great idea!

    Hey All,

    I'm new to RBR, but I've spent the last few weeks reading posts from version 4,5,6. There is a lot of great info, but it seems like the majority of the info I'm interested in is over a year old.

    Background: I ride a 58cm 2012 CAAD10. Initially bought the 105 version, but I have been upgrading components as I go. I train hard, and like to race. I prefer the sprints and breakaways instead of the mountains and despise bringing my bike to the bike shop... It always comes back worse then when I dropped it off, so I do all my own wrenching.

    I just finished building my 45mm U-Shaped wheelset and I love them... They ride great, and feel faster than my stock aluminum wheels.

    At this point I'm ready to leave my CAAD10 attached to the turbo and I'm looking at building my first (of many hopefully) Chinese OE bikes.

    I'm pretty sure that I've decided on the "Venge" style frame *SHOCK* (It seems to be one of the most common builds on here), but I was hoping to pull from the vast wisdom on RBR to help me finish this project.

    So first things first, what does the collective wisdom say about supplier quality? I'm looking at GreatKeen's GKRF01 (with graphics removed) or Dengfu's FM098. Does anyone have feedback regarding issues with the frame or issues working with the suppliers? Is there another supplier that you all would recommend?

    Thanks in advance!

    Eek, if 1/3 of the tube thickness (not the inner wall surface) is flash resin from poor prep that's pretty scary. As that's definitely not carbon mat. I'd actually hope it's fiberglass over resin.

    Ooity: Unfortunately unless you're going to give more info per the manufacturer/seller to see others have done you're a test group of 1.

    I cut the leftover tube again to get a closer look. Side note, the tube is a pain to cut. Terrible cut, but I wasn't wasn't trying to be accurate and was just freehanding it. Crush test. Looks like fiberglass to me. After being crushed, the small piece of tube deforms with a bit of effort, but it still holds its shape for the most part.

    Thought I'd share my experience building up my own carbon bike since I used the previous threads extensively while researching my own build.

    I started researching around the new year and with the spring and summer rolling around pulled the trigger on everything about 4 weeks ago. Went with the Velobuild r-022 frame as velobuild got great reviews, this was a popular frame, and fit what i was looking for not being a direct copy of a branded bike and as a plus happened to be one of the least expensive at $450 shipped. Got 38mm U clinchers from farsports as they were also a highly regarded retailer and seemed worth the extra price at $650. Finally got a SRAM Force 22 groupset from Merlin Cycles for about $700 shipped. Other parts were from ebay to finish the build, including a chinese version 3t aeronova bar. Total cost was about $2250 so under my hopeful budget of $2500 and weighed in under 15 pounds. I ran into no issue with any of the retailers and everything was delivered on time if not early and didnt have to pay any import fees. Luckily a friend of mine had everything built at the LBS for free.

    Took it out for my first few rides this week and could not be happier. The bike is incredibly stiff, but not uncomfortably so, and handles like a rocket. I previously had a Kestrel Talon (which may have been a size too big?) and it absolutely handles more nimbly, climbs better, and descends just as well. Flat straights may be about even or in the kestrels favor, but overall can say this was certainly an upgrade and will be more fun as well as unique. I've already had someone come up to me in the cafe after my ride the other day and ask me about it.

    Long story short I highly recommend going the chinese carbon route for those looking for a unique, light, and high performance bike on a budget. I cant comment on durability and obviously only time will tell about that.

    I got an FM098 last spring and its been great for me. No real issues working with DengFu. A bit of a language barrier and double/triple checking details of the frame build lead to a fairly lengthy email exchange, but when it was all said and done I got exactly what I wanted.
    5,500 miles later and its still treating me quite well. The stiffness and power transfer were greatly improved from my last bike (cheapo Bikes Direct). I was so pleased with the product that I went back to DengFu for some 56mm deep wheels to complete the aero get-up.

    RVA and RaptorTC, do you know how the cross section of the R022 and FM098 compare with the Venge? I think I read somewhere that the FM098 had s much smaller cross section ( different aero profile ).

    Also, what website did you use for velobuild? The website I've been looking at does not seem to have the extensive forum that these threads have mentioned.

    bvber,

    is there a specific part of the version 6.0 you are trying to direct me to? The first links brings me to page 1 and the second link is apparently forbidden.

    I have browsed through and searched the previous version threads. My concern is that much of the relevant discussion is over a year old.

    I'm not exactly sure. I can measure my 58cm frame if you'd like, but I don't know how it would compare to a Venge and I don't have calipers so the measurements wouldn't be super accurate.
    The good reputation of the FM098 and the fact that it comes in big sizes were the main reasons I went with the frame. The aero aspect is a definite plus, but wasn't the deal-maker for me.

    I would agree that the fm098 is very likely more aerodynamic than the r-022 (and i considered doing this build myself), but dont have any way to measure accurately or compare either.
