Sensah Electronic Groupset (14 speed?)

[jonathanf2]

While I support more options, I don't see much advantage with this over LTwoo eGR or Wheeltop GeX. For road it's all about 2x especially living around steep hills and fast flats. I'd have to run a 9/10-46t chainring to make this groupset useful for me.

Nice find about the website. Looks AI generated but whatever, it's something. I believe there's a mistake in the 14 speed cassette page. It says 11-46 but I think it's going to be 10-45 with the overhanging 10t like on the screenshots from the app and as suggested by someone before. Looks very promising especially because levers look good and feature 3 buttons each (I always wish levers had more buttons to control the head unit so I hope these will connect to them). Screenshots from the app suggest it has all the cool features to control indexing, seems done well. I presume there will be troubles with the removable battery that charges by usb C, wasn't wheeltop struck by SRAM with a similar design?

Something is off. I found some pictures on FB and clearly it's 11-46 but that cassette has 13 cogs only so maybe you're right and there is 14th cog as a cap but maybe it's just a 13 speed version cassette.
On the other side there is a mark MAX 45T on RD.

EDIT. Yes, I probably saw 14th cog on a different pic so I can assume that the cog progression would be 11-12-13-14-15-17-19-21-24-28-32-36-40-46

I count 14 sprockets on there with the smallest being 11. Definitely a lil weird. Unsure if the copy just hasn't been updated on the website.

That's definitely a 11-46 14sp then. I wonder what's the cog spacing and what chain they'll use. Even now with the current 13 speed HG cassettes on aliexpress I don't have a clue on what spacing and chain spec they use. It looks like it has two overhanging cogs on the back so I I hope there's not going to be any interference with the spokes.
Anyways, 418% is too little range and they'd rather add a 10t cog rather than some really small jump in the middle.

[elmeerkat]

Honestly that range+number of gears is basically what I have with 11 speed right now. I'm running 52-36 with an 11-32 cassette. I could definitely see some wider ranges being more popular, but it's basically on par with 11 speed in terms of useable gears.

The weird thing to me is that they went with 11t and putting more cogs inboard of the freehub. It makes me think you would need to shift the chainring inwards to have a more consistent chainline.

Also on the website it says to use 14 speed you need to use a udh dropout. I would think that would only be true if they were doing the 10t overhang method.

It seems like they maybe changed plans and haven't updated the website to reflect that.

Joe from China Cycling explained in a video from a trade show last year that you need UDH dropouts because they use a proprietary (narrower) UDH hanger. This way they gain additional cog space without the chainline issues which simply moving the cogs closer to the spokes would pose.

It's basically how the XPLR full mount derailleurs attach but without the outer plate. Which begs the question of how sturdy the hanger is going to be.


The range is a bit small indeed.

I'm currently running 1x13 XPLR on the road. 46X10-46 for instance is slightly bigger in range than 2x 50/34 X 11-34.

I was afraid of the 13-15 jump but I didn't notice it so far. But then again I've just moved to a very hilly region so I'm now constantly shifting across the cassette anyway.

For off-road use I'd be looking for something like 11-50 if they need to keep the 11 cog.


Cog spacing still isn't ideal. Without a 10t cog the 13-15 jump moves further into high speed territory so a 14t cog would be appreciated. 32-36 is a uselessly small relative jump in the low speed realm, 24-28 a big one in the middle. All in all you don't gain anything meaningful from the additional cog vs. the 13sp XPLR cassette.
Apart from lower price maybe.

I've been on XPLR 13s for almost a year and despise the 10-46t cassette. The lack of a 14t and 16t irritates the heck out of me. I hate the 13t to 15t jump. Campagnolo's 10-48t looks way better. I'd buy this group just to run that cassette.

On the other hand, the 11-46t cassette makes no sense. Not sure who the target is.

There's also a Shimano 10-48 13 speed cassette coming - if it's cheaper like normal Shimano cassettes then I could be very interested in running it with this or the L-Twoo group.

I'd be interested in that as well. But could be a while before that's released.

I haven't used it but on paper the Campagnolo 10-48 cassette looks worse than the XPLR.  The tradeoff for a 14t cog is a tiny 42-48 jump at the low speed end (should be 40-48) and multiple big jumps in  the middle. The Ekar GT 10-44 wasn't too bad.

At least the Whaleroad cassette looks like it's light. And good to see it's going to be a complete group set.

Odd to see they start off with 6-bolt rotors.
