Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!

[coffeebreak]

I've got the CR3 R325 38MM and I love it! I've got about 3,000 KM on it running tubeless setup. The newer version of the same model is lighter than the one I have.

How are the hubs? The listing says ratchet style but doesn't mention how many teeth. Sent a message to seller but he probably didn't understand the question. Are the hubs easy maintenance like DT Swiss? Also, loud or muted?

Edit - there are bunch of other wheels that don't have holes and are native tubeless. Definitely time taking process compared to rims with holes.

Just saw that and was trying to figure out where to buy!

They're Taiwanese based, so I doubt buying from AliEx will have much savings. The jockey wheels are on the Tripeak website, hopefully they'll come out later this year.

Something tells me these are going to cost a pretty penny at least in the beginning.

Anyone see these new offset oversized jockey wheels that allow you to use them on stock pulley cages? I think these are actually pretty cool.

I've used an offset upper pulley from Gearoop to replace the stock upper pulley of my R9100 RD to allow me to remove the 11T cog and add a single 34T upgrade cog from Gearoop as well to make my R9100 cassette 12-34T while retaining the stock cage.

The model and version that I have is the pawl type, not the ratchet one. The hub is pretty good and loud to my standards and still spins really well to this date. Quite easy to clean and maintain as well.

Sensah dropped mechanical 12 speed Team Pro shifters that are compatible with 11 speed R7000/R8000 RDs and I'm sure the R7100 105 12 speed RD.

I wonder if Sensah will go electronic shifting this year? Wheeltop doesn't ship to North America, so that only leaves LTwoo with worldwide distribution. It'd be nice have more competition.

I have always wondered about this. The speed capacity of rear derailleur does not matter? How are they making 12s shifters work with 11s RD..

Shimano's current road/gravel pull ratios are the same from 10 to 12 speed. The RDs are dumb, they just move according to the shifter indexing.  On my gravel bike, I'm using an Ultegra RX800 11 speed RD on my 10 speed GRX 400 shifters. So it goes both ways.

I'm using ultegra 11s shifters with GRX 400 RD too. So by that logic Shimano would work with SRAM RDs? I'm not entirely clear where the indexing part is set.

My disc rotors just arrived today. 91.16g for the 160mm 6 bolt version and also measuring about 1.6mm thickness. The standard steel 6x bolts come in at 13.25g for a total of 104.41g per disc. I'm currently using a set of TRP non-floating disc rotors that come in at 113g. I'll be able to shed about 21g per rotor or almost 1 AA battery per rotor! Lol

Used them today on a 125km gravel ride. All is well...

If you want them for perfomance reasons and not aesthetic reasons they're probably a waste of money as any chain efficiency gains will probably be offset by the larger bearings

I'll be curious which Chinese groupset manufacturer comes out on top. Even though LTwoo was first to electronic road shifting, they lost a bit of consumer confidence getting there. I feel Sensah has done a better job with quality assurance on their mechanical groupsets and Wheeltop solely focused on electronic from the beginning, though they're having a global distribution issue. I think if one of them secures OEM status for a major bike manufacturer that might be a determining factor.

I'm surround by hills where I live. I tested both regular jockey wheels and oversized jockey wheels on the same climb. I found the oversized wheels made spinning a bit more easier on the same uphill grind.

While I'm extremely sceptical you were actually able to percieve a difference that wasn't placebo, these have much larger bearings than is usual even for OSPWs (excluding the shitty absolute black one). That means there is more surface area making contact inside the bearing and with the seals, leading to higher friction losses.
