Re: Carbonda FM909
First ride finished. Great and amazing. I wasn't much slower than yesterday on a gravel ride. (Carbonda 505)I will change to sideloader cages , cut the handlebar down to 760mm and lower the front by 10mm. Besides that I never felt so good on a mountainbike before. (I started with mtb, realized then I like roadbikes, added a gravel and now finally came back to mtb )January 01, 2022, 01:33:52 PM |

Re: Carbonda FM909
Today I realized that the rear wheel is shaking slightly. I changed the rear wheel and also this wheel was shaking ( we do have some stock of stuff in the basement) Then I tested a shorter axle, everything is fixed now. Unfortunately it’s to short to use it, but in principal it showed that the axle is the problem, —> The original Carbondale axes is to long ( I removed the original text...here was something wrong, but the message stays true.. axle work 181mm is 2mm to long) January 02, 2022, 12:17:48 PM |

Re: Carbonda FM909
Forget what i wrote. It is not an edge within the axle that hits the hanger. It's the overall length. It's roughly 2mm to long. The hanger does not allow to screw through. It has an edge where the axle finds a stop. If you aim for 179mm length it should be good On the photo you see the outer side of the hanger. Do you see the tiny gap between it and the axle? That is after shortening the axle by 2mm January 02, 2022, 01:49:21 PM |

Re: Carbonda FM909
Still waiting for my frame, as soon as it arrives I will check if the axle fits. I bought: This axle seems to be to short. I tried a 171mm axle one hour ago and it is much to short. The hanger design allows you to see the axle and the thread.. 179.. maybe 178 or 177. But I wouldn't go shorter January 02, 2022, 01:56:19 PM |

Re: Carbonda FM909
I found drawing of 909. it looks like the total length of the axis is 178. I just didn't find the thread info. Will 12x1.5mm be ok? .. it looks like I found the right axle. The thread must be 1.0 That's the issue ..I only found long axles with 1.5 , which is why I took the Carbonda axle. January 02, 2022, 03:44:19 PM |

Re: Carbonda FM909
I’ve never heard of trouble with the OEM axles for the 1001/1002, which makes me wonder if maybe not all their frames take the same length and they accidentally sent you the wrong one? It's the axle dimension I was told at the beginning when I asked for that. 181mm length - it has 181mm length, so I got the 'correct' one. But yeah, maybe your assumption os correct and this is just a wrong axle.. the technical drawing is pointing to that direction. However, even if one of you ordered the 181 axle, you may just be lucky cause of tolerances..and if not you can shorten it, the thread length is sufficient for that. I would guess that their frames are very different for axle lengths. The 696 has different axle lengths than the 505, although the pitch is the same (1.5 I think.). If I would design a trail fully I would give it more thicker Carbon structures than the XC fully 909. And then it's just natural that lenghts differ. For the word standard and bicycles I can just do that:

Re: Carbonda FM909
Can you show me handlebar photo and cockpit photos? Is that photo showing what you wanted to see? January 03, 2022, 03:03:07 PM |

Re: Carbonda FM909
Hello, I attached the FC-M8100-1, which has 52mm. It's fine. I use 32T chainring. I don't know if you will get troubles with clearance with larger ones. Shifting is also very good, but that's what I expected from shimano as the crank is designed for 142 as well as 148mm rear January 15, 2022, 09:48:59 AM |

Re: Carbonda FM909
Thank's. I want to buy 52 mm because I will use carbon wheels from my old bike non boost for now. Will add conversion kit. Let's hope it will works fine. I bought them because they have a smaller q factor. I wanted to have the smallest possible value. I feel unhappy riding pedaling with the feeling of being a cowboy. January 15, 2022, 10:00:16 AM |

Re: Carbonda FM909
great news, it means the frame is very strong! After 5000km with my 505 , hitting so many potholes on the roads, jumping down so many sidewalks, riding easy trails... i checked my fork, no harm visible.. I was pretty convinced already that Carbonda has a good knowledge. Also the 936 runs quite good I guess
