Road Bike Frames, Wheels & Components / Re: Which OM frames are these?
« on: Today at 08:51:01 AM »
I LOVE how they're trolling Factor logo & paint schemes.
The RS1 looks like various workswell / yishun / lightcarbon models, it's for sure OEM.
The SL1 could be a VB 177, bearing in mind VB is a broker, not a factory. It looks similar, but slightly different, for eg, to a long teng 266.
I dont follow gravel much.
Those boutique brands are basically a scam, it's incredible.

I agree with you with the aesthetics of the downtube. It would look better and make more sense in a different (teardrop like) shape.
In terms of stiffness it maybe makes sense. I'm also no engineer in this area, so I'm only guessing.

Other than that, I like the design and geometrie of the frame.

For me I doesn't matter if I'll loose like 5W at 45km/h. I'm far from being a professional and I do not race.

That and other reason made me order this Frameset. I'll see how happy I am with it after it gets delivered and the build is done  ;D

You do you! i considered buying one myself for many weeks, and i'm not saying it's a bad frame, in fact i think it's a great frame! i was just detailing my thought process as i figured it could be useful to some.
Enjoy your new bike and post here about your experience and impressions!

While I don't really understand the squared design of the downtube, I can not imagine that an average rider would feel any difference. Especially because I guess the front wheel will make the bigger difference in that area and It should kinda shield parts of the downtube from the air flow.

I think the rider position, clothing, ... will make the biggest difference in aerodynamics.

we know for a fact that rider & clothing matter more than the bike itself, it's about 80% rider and 20% bike, afaik.
That being said, a bus shaped tube is a bus shaped tube. Even without a wind tunnel, we know that tear drop / kamm tail shaped things are more aero than round things, or boxes... And we know that buses aren't aero. You wont find an aero frame with a wide, boxy shape like that, nor will you find a frame that touts its aero prowess with a boxy shape like that - until proven otherwise, ofc. Given it's an ultra light frame, and making frames of that weight at this price point is a new phenomenon, and that LC doesn't make any aero claims, i think it's safe to assume it's not aero. Whether it matters or not is subjective. But even if it "only" costs 5W at 45kmh, i try to spend my money diligently, and given how incredibly hard it is for me to raise my ftp by 5W, if i'm going to buy a frame, and if i can, i'm going to avoid buying one that screams "i'm a bus". It's a guesstimate. It's also an aesthetics consideration, as i dont find that boxy shape appealing.

There might be some R&D costs that went into electronic group sets they are still trying to pay off, even if manufacturing should be cheaper than mechanical

That's wishful thinking unfortunately. These companies have been patent trolling for years, it's been the new rule of the game for many years. A friend used to be an intellectual property lawyer in London, representing the likes of Amazon. It is impossible to imagine how cunning these companies are at preventing competition. Amazon for example has patented so much shit related to conveyor belts that it's almost impossible to achieve their efficiency without tripping patents. Is it fair? Absolutely not.
SRAM and Shimano do essentially the same thing.
At these price levels, it's pure price gouging. Especially when you consider the price difference between OEM pricing and retail pricing, especially on Shimano.

Maintenance, Mechanics, & Tools / Disconnecting hydraulic hoses
« on: May 14, 2024, 02:45:15 AM »
Hello! Question, given i started using hydraulic brakes only this year.
On 1 bike, i have to invert left and right brakes.
On another, i plan to travel with the bike, so i assume i'll have to disconnect the brake hoses (ltwoo er9)

Question: do you automatically have to use a new barbs & olive every time you disconnect the hose from the shifter? Which presumably also means you have to shorten the hose every time you do that? Or you leave the barb but put a new olive? Or can you re-use the olive?
Also, i dont think i have such spares for ltwoo, what's a good source for these bits?
How do you seal the open end of the hose for travel without it leaking oil everywhere?
Is the barb + olive thing applies on both ends of hoses? I haven't tried to disconnect the hose from the brake calipers.
I do have a bleed kit with the right fittings.
Thanks!

That's awesome! i did design and print a rear bento box for my propel a couple of years ago. it worked great until it disintegrated in a flat second. My advice: carbon fiber cloth or (cheaper) fiberglass cloth to reinforce everything (or pre preg to make your life easier, presumably). My box failed in the middle at some random layer line, which retrospectively, makes sense. It was more of an experiment than anything, i was phasing out the use of that bike already, so i didn't print a new one and didn't get around ordering cloth.

i like the ghetto TT front end rig a lot, well done!

Yeah given the failure rate on the er9/erx, i'd wait a good 2 years after they RELEASE the triathlon version to put it on a race day bike. race bikes have to work on race day, enough things can go wrong without worrying about whether your group will decide to shift that day.
Eventually though, if they do get their act together, it will indeed be great. Should also open the doors to the "order a full custom bike from china straight to your door" market. Everything is in Xiamen, once their groups work, should be very doable to get someone to build you a bike, or at least most of it, the way Trek bikes arrive in shops, for eg (plenty of videos of Trek unboxing on YT).

I think I've made peace with not buying that frame. The down tube is simply too much of a square box in the wind. It can't possibly be fast, and I'm routinely doing 40+kmh on the flat so it matters to my riding. It's been helpful to see people's builds here to confirm that. The real Cannondale is nowhere near as boxy.
I also don't think it is a timeless design. That's subjective, but I feel the rim brake supersix (and first generations discs) is timeless. Along with various other frames. But not that one.
The thin downtube also raises questions a la Canyon. If you throw two bikes in the boot of the car, the last thing I want is a cracked frame in transit.
I thought I'd post because I long and seriously considered buying one.

The frames, that’s what I gathered from one of his video…

It might be true but I highly doubt it for various reasons. It it doesn't clearly say on the website you can safely assume that they don't.

I think PP offers value mainly on the QC aspect and communication after that it’s up to each individual to decide what is the value of service and if it aligns with PP mark up. The problem is that in a depressed used market or even brand new with 50% off being the rage, the value proposition of chiner built is a lot harder to justify especially once considering resale value.

QC: Panda podium inspects themselves every item they sell? There's no way, right?

This is funny, I just did the opposite. My LTwoo calipers worked fine, but the weight gain going with the ER9 was bugging me. I had ZRace XG calipers I bought on a whim awhile back and decided to install them. In the process I also opted to switch to 140mm rear rotors and cut a few extra grams. I didn't even do a proper bleed since I did a direct swap with the calipers. Brake feel is surprisingly good with the ER9 levers. The weight savings is quite significant because I cut about 100g from the calipers.

BTW - do you have a photo of your heat shrink cables? I'm using a coat of rubber cement + dielectric grease on my cables, but now I'm realizing it's a bit of a dirt magnet. I'd prefer a much cleaner application if possible!

Very pretty build (with the exception of that saddle bag :)!
What frame is that?

Are we doing update posts? 3000k update from me! Still working like a charm. I have put some "skateboard" grip tape on the seatpost wedge, as it wanted to reduce the torque on these bolts after what I've seen in this thread. Seatpost now holds with 2nm on the bolts.

And I can confirm you can actually ride TT on this, if you are brave enough and have a 3d printer, lol. A bit sketchy, but I wanted to try out the TT position for a bit before I pull the trigger on a new frame

Yes we do want update posts, it feels to me that chinese frames are now safe to ride, so day 1 posts are helpful about QC (facing, round holes, clean layups...), but now the question is about the long term performance / behaviour of these frames, and how they compare to "normal" bikes.

Also, please post more about your TT rig, i'm very curious! i just sold a giant propel i had turned into a TT rig (but slightly too large), with a bunch of 3d printed bits (i have a printer too), so i'm very interested in all things TT, and your rig looks very intriguing!

I really like these emonda looking frames. If you ever see one capable of taking 32C, please message me.
I actually rode today with a guy who has a 6000 EUR emonda di2. Such a nice bike. He's an ex pro so in my book he's allowed to spend 6k on a bike :p

Super nice rig. Looks nicer than some of the girls I've had in my bed.
