Re: Carbonda fm936 Thoughts
...Just go with the press-fit setup... All my bikes are PF, but the hole of BB92 is only 41mm, which leaves not much room for bearings around a 29/30mm spindle. The bearings are just to thin to last, on the dry, and even more if you ride in the wet. August 25, 2020, 03:50:31 PM |

Re: Carbonda fm936 Thoughts
I ordered this: https://www.aliexpress.com/item/32896597801.html?spm=2114.12010612.8148356.2.749f4f0dI16PK5 I have it on my MTB, but the PF30 version for a 46mm frame hole instead of 41mm. The ZTTO BB shell is nicely done, very comparable to the much more expensive ones from WheelsMFG. The bearings coming with the BB were crap and I changed them. But these are the sturdy and cheap 6806. In the case of BB86/92, you'll see the bearings are thin, small balls, that do not resist long to the forces. And seize very rapidly if ridden in the wet or mud. BB92 is a Shimano standard, that is designed for 24mm spindles. August 25, 2020, 04:04:08 PM |

Re: Carbonda Gravel Carbon frame CFR707
I've built quite a few 505, as a versatile bike. You can use on road, or gravel, just by swapping wheels. It has very good handling and is looking great on both. There are multiple things that surprise or sadden me here: The BB86, they were offering the 505 in BB386 The chainstay length, compared to the geo drawing, don't you think they did put 650b wheels for the picture? The gap between the seat tube and tire is so huge. The 30,9mm seat tube will be harsher than a 27.2. For more dropper options? Oh my... The headtube is not the usual tapered, but two 52mm holes, is this for full internal routing? And I'm not particularly fond on the moustache look of the seatstays connection.

Re: Professional Inspection
Do you know Raoul Luescher from Luescher Teknik ? For instance, he cuts frames in two, to inspect them and report on youtube: https://www.youtube.com/channel/UCY9JUMYI54lLOHpb_zbIedQ If you want a true inspection, you need to find a real composite material specialist like him in your area. I would love to know the result of such investigation. Although this would only be a test on a single frame, not the whole Carbonda production, which seems great from all the reviews for years. I'm not even sure Carbonda would take a frame back because they discover you a void in the carbon layup or wrinkles somewhere. It looks many branded frames have them, and they are massively ridden, even raced. Ask Carbonda what they think ! I would save that money for better components instead  August 28, 2020, 03:41:24 AM |

Re: Carbonda Gravel Carbon frame CFR707
I'm still interested in those new Workswell frames, if I ever see any feedback. Which ones ? Do you have some links, pictures ? August 28, 2020, 07:54:47 AM |

Re: Carbonda Gravel Carbon frame CFR707
Thanks for the reminder ! http://chinertown.com/index.php/topic,2987.0.html On their facebook page they have a picture from March, of the 208 that looks quite better than the CFR707.

Re: Carbonda Wheelset to go with the Frame
1. Carbonda has a 240S boost wheelset to go along with this, has anyone bought and / or has any feedback on itThey probably make them built by someone else, it is not their specialty. ligthbicycle.com or farsports.com dedicate themselves to wheels and I would go with them instead. 2. Does any one have a spreadsheet with recommended components, some of you had created excel, can you send it over, I can PM my email address.My very high end build spreadsheet Here are some usual parts that may miss, delaying your maiden ride for a few days: A front brake adapter for 180mm/200mm or 160mm/180mm rear disc, if it applies. Shifting hose/cable/cable stops, brake hose/olive/barb may miss from the groupset you buy, so check with the vendor. A bleeding kit and compatible brake oil, in case the reconnect of your rear brakes hose goes bad. If you get a 240S hub with lockring, you may need to buy a ring for 15/20mm axles, as there is no room for the tool to tighten the disc. Tubeless tape at the right width, and tubeless valves at the right height. Having sealant too, Orange Regular is by far the best, efficient, easy to clean, doesn't stink. 3. Should i get additional hangersI never had to use one, but I always order one spare that I take with me when traveling. 4. I see that the recommended bottom bracket is BB92These are two quite contradictory statements If you plan to use a DUB spindle, BB92 is not a good choice. The reason is a 41mm hole doesn't leave much room for a BB cup and bearings for a 29/30mm spindle. Meaning you will change quite a lot of bearings along the life of your bike. Worse, after a while, changing them so often is tiring, and you end up used to a poorly efficient and grinding drive train. If you plan to use GXP spindles 24/22mm, BB92 will work. Beware GXP has its woes too, as the left bearing is particularly stressed and die prematurely. Carbonda will not install a BB for you, and the tool you need is a Shimano type BB tool you can find everywhere. If you don't have one, the ZTTO one is good. And it is the same tool needed for 15/20mm brake lockrings. August 29, 2020, 12:29:40 PM |

Re: Carbonda Wheelset to go with the Frame
... wow, just looked at your spreadsheet. Really a high class build! It would have cost around 11000€ if you would buy something at Scott. Yeah, lots of €€€ in the end. I've had my covid/carpe diem moment when ordering some of the parts. Be sure I'll post pictures when we build them ! This is the first time I buy components before receiving the frame, and unfortunately the first time I wait so much for it  They are selling the 936 like hot cakes, and BSA seems strangely in less demand.

Re: Carbonda Wheelset to go with the Frame
So you ordered the 936 with BSA? didn't know that was possible. They had BB386( a 46mm hole instead of 41mm ) for the CFR505 for a long time, I thought it was the norm. The bad surprise came when ordering, I didn't want that Achilles heel on my brand new MTB. I was going to drop it, but Wing told me they had BSA, which allows to put cheap and big industrial bearings. If you live in a dry area, maybe it is less of a problem. But from my experience and from what I read on the web, it is better to stick to a 24mm spindle. You can always change it later if there too much trouble. September 01, 2020, 02:43:28 AM |

Re: Carbonda fm936 Thoughts
...All home builders should invest in a hanger alignment tool... Meanwhile you can put an Hex5 key in the hanger screw. And counter-bend the hanger, generally a little up and/or left. Comparing its alignement with another bike with the same dérailleur. Or look for web pictures, on how it generally looks. September 02, 2020, 06:09:25 PM |
