Lol those holes are the most retarded pattern imaginable, it's almost funny. imagine the donkey who came up with the design.

They work fine! I double checked my gravel bike brake pads which does long descents on dirt trails and there are no deep track lines on the pads. My 2x160mm rotors are 1.6mm thick and feel quite sturdy. For someone to toast their rotors and dig tracks into their brake pads suggest to me they weighed like 130kg and had zero clue how to feather and modulate front/rear braking! There's a reason they have bigger rotors for bigger riders!

My ER9 is still going strong. When it works, it's f**king great! Though I'm not ignoring the problems. Hence why I don't ride my ER9 bike in the rain & don't wash it with a hose, I rotate my bikes to minimize wear-n-tear and I don't do things like shifting both the left/right shifters at the same time.

Also I'm theorizing that some aftermarket batteries might be an issue as well. That's the one variable that differs between all the working/non-working units. This is probably why Shimano uses their own proprietary unit and SRAM insist on only using their OEM batteries. I could imagine a sh**ty battery could potentially toast the ER9/X RD electronics.

Even with all the issues and the non-existent LTwoo support, I'd probably buy another ER9 groupset when it's on sale. The performance-price-risk factor is still worth it for me.

And the disaster continues. 3rd dead er9 RD. again, randomly and for no reason. Was riding with my friend, who really hasn't used his new bike much, less than ten rides for sure. Dry, 20 Celsius, smooth asphalt, largely flat. 35km into the ride, his RD dies like the other 2. So there's my er9 on which I've put almost 4k km that's working fine (sometimes it charges weird, but at least it's working), and the fifth one isn't being used because the front wheel on that bike broke during a crash and we're still waiting for a replacement.
At which point can I preemptively ask for extra spare RDs? I'm happy to beta test, but we can't be 6 weeks without derailleurs every time one kills itself.

It probably wasn’t a good idea to buy 5 ER9 groupset especially since it seems LTwoo hasn’t ironed out their issues. My ER9 is still working fine, but I’m always checking to see if it’s functioning! I’m already eyeballing some cheap mechanical 105 12 speed shifters or just drop back down to 11 speed with spare Ultegra shifters if my groupset does die!

BTW - LTwoo updated the app, but I don’t see any new features. It looks like they updated it to recognize the upcoming blue edition ERX/9.

I have to say that I strongly discourage the use of this disc rotor. It completely neglects mechanical simulation and the bracket itself is prone to fracture. Furthermore, the pattern design is a mess, with hollow patterns distributed unevenly on several concentric circles. As a result, the friction rate of the entire disc rotor in the radial direction cannot achieve consistency, leading to the formation of grooves on your brake pads... It's a design that leaves me speechless.

The issues mentioned above are not exaggerated claims but rather highly probable events that have occurred multiple times on Chinese forums. I don't want anyone else to become a victim of this disc rotor.

I'll just flip the pads around to even them out. I rotate my bikes every other ride, so I'm not too worried!

I had a problem getting the ER9 LTwoo calipers+140mm adapter plate to line-up properly using 140mm rotors on the rear. I tried it on 2 different framesets and both of them would not line-up properly. The strange part is that I had no issues running 160mm rotors with the Ltwoo calipers+adapter plate. I ended up switching over to ZRace XG calipers which required no adapter plate. I literally just unscrewed the Ltwoo calipers and screwed in the Zrace calipers, plug-n-play style. They work well enough with no issues on long descents.

Seen it last week and it looks like the cervelo/focus one, but it's not even cheaper. Got one at the LBS for 25CHF, seen it even cheaper on bike24

What are the 150/102/135mm sizes?

For people who want to spin at 400 RPMs!  ;D

Yeah, I think the seller should clarify that part.

Anyone see this new carbon crankset? It has 165mm, 170mm and 172.5mm crank arm lengths. The Riro and Racework cranksets are only 170mm.

Road Bike Frames, Wheels & Components / Re: Delihea CK-Two/One Framesets

Not familiar with the name Delihea.

I note the shop listed on AliX on Oct23 only. Their business licence says ... ELECTRONIC commerce, established Mar21. So...
There are a few YT videos of people reviewing Delihea bikes, from much before 2023. From people buying on AliX.
Can't find a website for Delihea.

the ck-two that takes 32C looks VERY interesting. But that frame ticks all the boxes for 2024, i'd say.

I dont think i've seen this frame before. The other one with 28C looks much less future proof and relevant in 2024.

Yeah now that I look at it, the CK-One might be an older model. The Delihea brand has been around for awhile. I think they have small presence in Asia. They used to sell from their website, but I believe they have shifted mainly to AliExpress for selling their framesets. Most of the frames appear to be just rebadged TFSA frames, but I can't seem to locate who makes the CK-Two.

Threaded BB68 or T47 both appeal to me in terms of maintenance and 32c tire clearance makes a huge difference in flexibility from light gravel to dedicated road bike. The only other frame that ticks the same boxes for me is the ICAN FL1 which comes in at sub-800g, 32c tire clearance and T47 threaded bottom bracket. I'd be curious to see how much cheaper the CK-Two would be during an AliEx coupon discount sale. I only wish it was a sub 900g frame.

The BXT 135 gravel frame set is $345 USD right now with free shipping.

https://a.aliexpress.com/_mLk2N9o

SPCycle also has the G056 gravel frame which seems a bit more modern and I've seen this frame under other brands. (It's a bit more expensive, but I'd wait for an AliEx coupon sale).

There's also a TX-R7101-SGS derailleur mentioned there - TX is for road, but SGS is long cage. It might be that this is a wide-range 2x option.

If it's a 2x gravel electronic groupset, I'm sold. I hate 1x. I prefer riding to the trails which requires doing road miles beforehand. I find driving to a trail just to ride a bike to be incredibly lame. Probably accounts for why most of MTB'ers I see in my area are switching to e-bikes to make up for their lack of fitness!

Maintenance, Mechanics, & Tools / Re: Disconnecting hydraulic hoses
« on: May 16, 2024, 06:49:53 PM »
I'm curious with the hydraulic hoses on fully internal frames. On semi-internal frames you can just detach the stem/bar from the bike and pack the bar sideways next to the frame in a box.

On fully internal frames, is this not an option for travel? Do you have to detach the hoses for travel? Sounds like a big hassle if that's the case.

Just a heads up with the ER9. I found if shifting maybe 3-4 gears without pedaling, you can derail the chain and jam it on the RD cage. I also ended up scruffing up the inner cage plate. I'm way too OCD, so I removed it, sanded it down and repainted the cage matte black with some paint primer.

It does make me wish there were some optional cage replacements in case of major damage.

Thoughts on shifter forward play?  For me, It would have been nice if that movement wasn't there but not a deal breaker.

Both my Ultegra and LTwoo ER9 levers do that. If you adjust your lever reach, there will be slight play. Not really a big deal.

On the plus side of LTwoo's missteps, it's allowed more Chinese groupset competition to catch up. Wheeltop and soon Magene will also be in the electronic groupset market. I haven't heard anything from Sensah, but if they do make an electronic groupset there will be four potential players. Whoever can step up quality and customer service will own the Chinese cycling market which is on the rise.

I think within the next 3-5 years one of these companies will come out on top. Also that's the number that was thrown around for a Chinese sponsored cycling team to enter the World Tour. That means one of these manufacturers will really need to step up reliability if they want to represent.
