Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
One thing I’ve wondered about is the pivot chainline on the 1003, and how much running a bigger chainring would influence this. Did some testing in linkage and anti-squat does change a lot between a 28t and a 34t chainring, 34t going from 100-25% and 28t from 140-75% in 15t on the cassette when going through the travel. But with the smaller chainring pedal-kickback might be an issue. October 31, 2022, 02:52:37 AM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
hello everyone! long time lurker first time poster Thanks to the guidance in this forum I bought a Carbonda FM936 two years ago and have really enjoyed it since. It's the perfect steed for crushing New England XC Singletrack. I also have a Ripmo that I ride when things get steeper. This frame intrigued me as the Ripmo can get interesting plowing through rough stuff at the bike park or otherwise so I pulled the trigger a few weeks back. I built this up last week and had a chance to get out and pedal it around the local trails today. It is quite a beast - definitely heavier and different to pedal than the Ripmo (is there a better pedaling platform than the DW link??) but I was pleasantly surprised at how well the FM-1003 pedals and climbs for a 180/180 frame. I used to have a 160/170 Rallon and this pedals better than that frame. I deliberately started with a 30t chainring to try and reduce pedal bob associated with the suspension design, and I think it worked well. The float X pairs really well with the frame, gives plenty of pop and play while being supportive. I will also be trying an X2 to see how that feels. So far, I'm really happy with the design of the frame - the internal routing is way better than the FM936 and the linkage, etc. all seems very beefy and overbuilt. My only complaint is the paint job leaves something to be desired...the clear coat seems thin, especially around the cable ports, and already shows some wear. FYI it takes a 200mm rotor in the rear, which surprised me. I have to return some adapters now! I am taking it to the bike park tomorrow and looking forward to putting it to the test. Ignore the mismatching wheel/tyre set...waiting on a new rotor to switch the rear wheel with my conti's.    November 02, 2022, 12:16:33 PM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
Damn what bike parks are open into November? New England's got a secret... Highland bike park - they're typically open through veterans day. The weather this fall has been amazing, and we are looking at 70's again this weekend. Thanks, global warming?? The bike was exactly what I was expecting - point and shoot. Where I had to be more selective of line choice to go fast through rough stuff on the Ripmo, you can just point downhill and go. Soaked up those late season braking bumps with ease. It has a longer wheelbase and longer chainstays so of course it doesn't handle as well through tight turns and slow tech but that's to be expected. Did half my runs with the float x and half with the x2. The float was definitely more fun, but the X2 held up better in the chunk. So far this is exactly what I expected and wanted out of this frame. We'll see how it holds up long term but for now I'll consider this another win from Carbonda. Would be interesting to get a comparison against the Transition Spire...the Spire is a well reviewed bike that is more so in the FM-1003's category than the Ripmo. November 03, 2022, 03:11:01 PM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
Good to see more people getting into this frame I’m pretty excited to get one, as much as it might be overkill for a lot of my current pedal-up trail networks…because the one mild weakness of my FM1002 is the linkage flex. It’s reasonable for a trail bike like the 1001 which it’s also used on, but starts to get more noticeable at times when attacking gravity trails at high Gs/speeds. Not so much an issue of handling as one of ride feel, but one of the things I’ve been craving with this bike is a rear end more like the tank-y aluminum linkage of my previous GT Force LTS. The FM1003 would seem to be able to deliver that, with the solid rear triangle. And it’s so capable that I could see myself riding more park next season. It would be a very interesting day on the hill if a bunch of us New England riders with 1003s ran into each other at Highland in the spring… November 08, 2022, 12:59:56 AM |

Re: Hardtail similar to Specialized Epic
I'm a big fan of my Airwolf YFM-026. Others have had issues but I've had no problems. I use mine to ride to work, to race CX and for some pretty hard riding on Vancouver's North Shore and in Squamish, BC. Post here: http://chinertown.com/index.php/topic,3409.0.html November 15, 2022, 06:01:38 PM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
You really don’t need to. It’s nothing at all like we’re talking about with the AM831. Firstly, I’m making a comparison to my last bike, a GT Force (LTS V1) there, which has one of the most overbuilt aluminum 4-bar linkages out there. Even that has some movement in it which I always felt was a little uneven side to side in that way almost all 4-bars are asymmetrical to accommodate the chainring and guide/bash mounts. The 1002 is much more even in the movement it has. The 1002 uses the same linkage as the 1001, so it’s built a little bit on the lightweight side for an AM bike. The rocker arm in particular is daintier than I would’ve designed if I was engineering a 153mm bike of this caliber. When you lean the bike over hard on intense high speed/high-G trails, for someone like me at ~200lbs without gear, that’s mild but noticeable versus a giant hunk of aluminum like the Force LTS V1’s rocker arm. The Force V2 (current model, high pivot 4-bar) actually shed a ton of material from the linkage while keeping it aluminum even though the front triangles are now exclusively carbon. Now, I was also talking about my 1002 at the end of the season with 725mi on the original bearings which have never been opened up or greased. I suspect they have at least a little rust and play in them by now, which made apparent rear end “flex” more noticeable. It was never a bad problem, or significantly affected handling though I did sometimes find myself wishing I had the money for fresh Enduro Max bearings sooner to see how much it helps. I’ll be doing that next spring. In conclusion, all this was as by way of comparison, both to my last bike and to what I’m considering as a second bike to go with the 1002 — the 1002 is an AM bike with a trail bike rear end and I’ve really enjoyed that in most ways but I think a 1003 will be inherently stiffer with only a single pivot and one piece, enduro-weight rear triangle. It will become my big mountain enduro & park weapon with some of the current 1002 parts like a Fox 38, while the 1002 will get new/refreshed bearings, a 36mm fork, and be my daily driver light-AM bike for local trails. There’s no inherent problem with the 1002 of any kind, it’s just firmly an AM bike and the OEM bearings are probably not quite up to the level of punishment I dished out this year…whereas I’d like to add a really stiff enduro tank to my stable, and this time I will give the bearings a thorough examination/greasing before the build. Might even just install Enduro Max on the main pivot at least. November 25, 2022, 07:41:18 PM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
I see that Sherpa appear to be selling this frame as the Olympus and some build options use a coil shock. Looking at the linkage plots in the first post I would have thought that this frame wouldn't suit a coil shock as the leverage ratio drops pretty linearly throughout the travel, wouldn't a frame designed for a coil shock have a progressively increasing leverage ratio throughout the travel? Not at all. You can find plenty of heavy hitting frames with pretty linear leverage drops fit for running coils, including VPPs like the Santa Cruz V10/Nomad or horst links the Specialized Demo/Enduro. And then you have frames with decreasing progressivity like the YT Capra or the Canyon Sender, perfectly fine running coils as well. Increasing progressivity will mean diving through the mid travel and lower dynamic ride height, so definitely not only beneficial. But as ever, it all depends on your personal preference and riding style. Numbers will only take you so far

I suppose you could use a progressive spring on the coil shock, but I have no idea how well these work? Well, you get all kinds out there. People swore up and down that a coil on the gen 3 Trek Slash was brilliant but the leverage ratio of that bike really wasn't meant for one. That said, the leverage ratio is quite similar to a lot of 2018-2021 Enduroy bikes, most of which worked fine with a coil - it's nearly bang on the Instinct BC edition, for example. Don't look at reach as the sole determining factor to bike fit. Look at (E)STA, ETT, Front center, and reach in combination to get an idea. There's a good chance your medium giant has a slacker STA than the 1003s, putting their ETT numbers pretty similar. November 27, 2022, 10:38:25 AM |

Hit with a coin the area around and on the hit. If the sound remains clear, not muted, ride it happily December 20, 2022, 08:07:14 AM |
