Re: Tubeless Wheel Plugs.
With tape you have two edges which are the only main points of failure and the tape often extends so far from the spoke holes that even minor bubbles or wrinkles etc can’t break the seal. With plugs you get 28-32 circular points of failure and the plugs can become misaligned during or after installation in ways that aren’t possible with tape. This isn’t to say that good ones can’t work. It’s saying that it’s an inherently more failure prone system and not by a little, but by a lot. October 03, 2022, 01:13:13 AM |

Re: Carbonda Fm-1002 vs lightcarbon lcfs947
There are at least 2 or three aftermarket 1.5/1.5 headset options out there. FSA and Ritchey to name a couple. I’ve been perfectly happy with my FSA, though I definitely noticed some issues with the Carbonda OEM headset. October 07, 2022, 01:36:35 AM |

Re: Tideace 2022 New Enduro Mold FS838 Being Production
The Norco version also has some pretty unique replaceable dropouts which this design lacks. I have to assume there was a good reason Norco used them, though I haven’t been able to figure out what it is. This design needs tight tolerances, particularly at the main pivot and the idler. It wouldn’t take much of a loose tolerance in the right place to turn this into a self destructing wet noodle. Most significantly, idlers need to be replaced regularly. Will this be standardized on the 838 so third party replacements fit, or would we need to get them from Tideace? All significant considerations. Personally right now I’m looking at the FM1003 instead because it’s a much simpler design that doesn’t need extensive rider testing before I’d trust it (and has already been on the trails all summer under one member here, with a second build underway).

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
I'm not sure about this, but I think the linkage design could be following the Canfield Balance Formula. If so, then aside from being heavier, this would be the best climbing bike from Carbonda. Revel has a few CBF bikes. I've always wanted to try it. Not really. CBF requires dual links (top and bottom). This is a linkage driven single pivot. I’ve always wanted to try Revel/CBF too, but the 2.4 tire limitation on Revel frames has always been a turnoff. I’m a 2.6 guy all the way. October 17, 2022, 04:23:03 PM |

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
It’s definitely been interesting watching Sherpa roll out their “Olympus.” At least we get to see more examples of 1003 builds in the process. Also very interesting that they are offering a 170/170 version and a 180R/200F dual crown version (suggesting the head tube can handle that fine). Seems like the 170 wouldn’t handle as well for gravity riding but I’d be curious to try it if I had the chance. I assume the shock is just under-stroked to 62.5mm and the shorter form therefore steepens the head angle. I have definitely thought about short stroking a 1003 but that wouldn’t really serve much purpose and putting a 170 fork on seems similarly pointless except for Sherpa to create an extra price point/“model.” October 17, 2022, 04:27:50 PM |

Re: FM1001 / FM1156 - 135mm frame
It can be indeed a great way to prevent the bar going over the top tube if you crash At the angles they’re set on, and with some slack inside the frame, I’ve had the bars go past the top tube and they do pull a bit but don’t actually yank the bars to a hard stop as they spin unless you go way past that 90 degree angle. You can definitely run them a lot shorter than with some other frames (particularly externally routed ones that run along the down tube with exit points a lot lower or further back than these ports) without it being particularly risky. That said, I would never in a million years run my brake line on the outside of the fork, any more than I’d ever be caught dead running the kind of huge, tree-hooking bullhorn bar ends my first MTB came with in 1993. Partly due to the substantial possibility of literally being caught dead running them. Because they killed me. But mainly because they’re bad bike fashion. Which is a far worse offense!

Re: Carbonda FM 1003 / Flybike FM 1266 180mm "Super Enduro"
So tried to check this frame in linkage, anti-squat is very low. That is of course not exact and very theoretical. Can someone who have actually ridden this comment on how it rides and especially pedal-bob compared to some other full-suspension bike? That’s odd, maybe you weren’t accounting for the way the shock driving linkage behaves? Take a look at the Sherpa video that shows the linkage movement, it isn’t as simple as it looks when it’s just sitting there (a dual stage movement, instead of a single arc). Last time I saw a kinematic graph for it from Carbonda, everything looked good except the anti-rise is a bit low so braking forces can interfere with suspension movement a little more than is ideal. Not a huge problem. Anti-squat looked fine, and the couple of owners who are out there so far seem to have reported great pedaling performance. October 27, 2022, 01:55:11 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: New Lexon spirit
The weight difference is going to be in materials (that nanotube reinforced resin in the Scott is a big advantage over regular carbon-resin matrixes) and the fact that the layup is likely a lot less optimized, partly as a result of the materials difference. I bet the pivot bearings and hardware are also a little heavier. Personally I’d like to try one of these out, just to see what it’s like; I’ll never put down the money for a branded XC bike on this level and it would be neat to experience this particular suspension system first hand. Wouldn’t expect it to be that special in terms of kinematics but the low slung center of gravity would probably be nice, and it does seem inherently pretty stiff. November 23, 2022, 01:45:52 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 |
