Sensah Electronic Groupset (14 speed?)

[Ludo]

that's gore for weight weenies holy shit.. i always welcome competition but that weight and the 1x only made me lose all interest. tracevelo has one though, groupset news are always exciting

When you get a whole bike with that groupset for the price of the durace groupset, you probably expect a little bit of a compromise

[Takiyaki]

I wouldn't say the weight is really an issue. The SRAM Red XPLR derailleur weighs 375 g without the battery (battery weight 25g), Force is 419 g without the battery, while Shimano XTR is 390 g and XT is 450 g, both with the battery.

Even if Shimano moves to 2x13, I don't think there's much more weight to be saved on the rear derailleur. At this point, the limitations are probably more physical than something you can overcome by just adding a few more cutouts here and there. So if you really want to save weight, you'd probably have to stick with 2x11 or 2x12. I just can't see the derailleur getting significantly lighter from here, apart from custom builds where individual parts are replaced with carbon.

So for road, at least, I'll probably stick with 2x12, while for gravel I'll go 1x. From the looks of it, the RD weighs 396 g (the battery is 41 g), although it's not clear whether the 396 g includes the battery. Either way, it seems pretty comparable to the big two.

And as long as they offer a cage option that supports 10-52T and 3-14 gears, this could at least be an endgame groupset for me. It would tick pretty much all the boxes I'm looking for: 10-14 speeds, type-c charging, mineral oil, and SRAM's new E1 brake logic.

As long as it works reliably, it seems like a perfectly viable option to me.

Last sentence is a very big if!!!

105 Di2 shifters + FD + RD is not far off in weight from this 1x deal and you obv get way more gearing range

Very tough

What are you guys thinking, New Whaleroad = Sentyeh ? https://www.mywhaleroad.com/r7/

If you open Whalroad's Privacy Policy https://www.mywhaleroad.com/userprivacy/en it says "Sentyeh Privacy Policy" in the Page Title... 


EDIT: another think: their Android App package id is ... obvious play.google.com/store/apps/details?id=com.mywhaleroad.sentyeh.global

[Ultramic]

Someone has already confirmed that the whaleroad app is not compatible with the Sentyeh groupset.

[yappy]

It's likely a difference similar to that between Retrospec and Sensah.

[humpty_dumpty11]

first review is out. Hopefully they will bring out 10-52 cage version soon ;(

From the Sentyeh flagship store on TaoBao the cassettes are:
13s: 11,12,13,15,17,19,21,24,28,32,36,40,46
14s: 11,12,13,14,15,17,19,21,24,28,32,36,40,46

However they don't actually have any cassettes listed, either in group set packages or individually. Customer service said they're coming, but didn't give any estimate.

Looking at my current gearing and my usual riding, the 14s with a 50T chainring wouldn't leave me wanting anything.

I would rally like to see 11,12,13,14,15,17,19,21,24,28,32,38,44,50

[pedalino]

So, the most reasonable choice for now would be to use a 13-speed cassette and chain, or else wait.

A good, lightweight, affordable 13-speed cassette that starts with a 10T cog? And a chain—preferably flat-top?

Looking at this I can see why SRAM and Campag start their cassettes with a 10 (or 9). Bearing in mind a lot of gravel climbs are short and steep I'd want a 1:1 or below ratio. If you're running a 46T means you lose a fair bit of top end, which would annoy me based on the amount of (often downhill) road I need to do to link gravel trails up. Or you could go for a 50 then I'd have a worse climbing ratio than my road bike that uses a semi compact with an 11-34 cassette.

The actual groupset itself looks great - SRAM ergonomics and gravel bike optimisations but using mineral oil. But it would be much better with a 10-46 Cassette (possibly using microspline).

According to the FAQ the derailleur is actually compatible with a 10T, they just haven't chosen to make the 14s cassettes with it. So if you wanted to use it with a 13s cassette with a 10T, or if someone comes out with a 14s with a 10T later it'd work.

Some cassette 13s 10-46?

[jonathanf2]

There's no way I'd push a big cassette without a 10t or 9t small cog. Also with a x-46t cassette I'd probably need to run at least a 46t, but I have so much climbing in the area I'd probably run 44t or smaller chainrings to get that sub 1:1 gearing. The Whaleroad groupset and app look great though, but 1x is just too limiting outside of flatter terrain.

I wonder how complicated it is to add a front derailleur in terms of patent obstacles?

I mean going up and down hills is exactly where an FD shines. IMO only reason to go 1x is tire clearance

[hubba]

10-46 14spd would be great for gravel I could run a 42t chainring. With 11-46 it's limited on high or low end.
