L-TWOO R9 2x11 hydraulic questions.

[Takiyaki]

Anyone running these with Shimano derailleurs? Is that thumb shifter comfortable? How do they hold up over time? And how much do the shifters weigh? I feel like these shifters + Shimano derailleurs are a cheap weight-weenieish setup.

I didn't like the Ltwoo thumb shifter. I couldn't fully wrap my hand around the shifters because it was in the way. If you shop around you can find Ultegra hydraulic shifters for a good price. Also I'd rather run the  Sensah Team Pro HRD shifters, mainly because I prefer the solid click shifts especially on the left shifter. If going mechanical those would be my 2 choices.

I have a pair of R9 2x11 shifters that I intend to match with an Ultegra R8000 front and rear setup. Opting for this combination was a budget-conscious decision that appeared to be the most sensible choice. Although I haven't completed the full build yet, my initial impressions are positive. Each shifter weighs 250g, and considering the price I paid (around £35), the quality of the rubber seems satisfactory. If everything functions as expected, this could be an effective money-saving strategy, but I cannot guarantee its long-term performance. I'll provide an update once the bike is fully assembled.

I'm on the fence about Sensah. I've heard mixed things about the comfort, specifically around the length of the shift throws. Ultegra 8020 shifters seem pretty common so I might lean that way. Seems like all the mechanical hydraulic shifters are boat anchors anyway

given the state of the 2nd hand bike market, if you can, get Shimano and not Sensah. I've had mixed experience with Sensah 2x11 carbon. Shimano just works, vs Sensah is largely untested, and if you have warranty issues, you find yourself without a bike for 6 weeks if you're lucky, to deal with back and forth, explanations, shipping and so on. Although, in my experience, Sensah just tells you to eat a d1ck and doesn't honor any kind of warranty anyway, so that simplifies things.

Yes, just get second hand ultegra. It just works.

The current batch of Sensah shifters have all the kinks ironed out. I'd go Sensah over LTwoo mechanical any day just so I wouldn't have to fiddle with that dumb Ltwoo thumb shifter.

Saying that, 11 speed Ultegra mechanical is the way to go or pick up 12 speed 105 R7100 hydraulics. They seem to be priced similar.

I'm starting to appreciate 12 speed and the better gear spread you get as you size up on the cassette.

Hi, I'm currently building a new bike with this groupset and I have two questions.

• The front derailleur seems to have 4 speeds instead of 2(I'm new to bikes so please let me know if I'm just stupid and this is normal) - i.e. it clicks 3 times when shifting up and 3 times when shifting down and I'm not sure if I did something wrong with the setup. Shouldn't it be just 1 click down and 1 click up?
• When I try to shift front derailleur to the big chainring, the chain get's stuck in between derailleur cage and chainring - see the pictures in attachment(not sure if it's clearly visible). I haven't lube the chain yet - can that cause it or something else is wrong?

• Those are trim positions to prevent chain rub on the front derailleur when in crosschained gear combos. See https://www.youtube. com/watch?v=CR8jyNgoS0U for a good little visualization (remove the space in the URL - youtube links are really weird on this forum.)
• The chain getting stuck between the front derailleur and the chainring is how shifts happen - the chain is forced into the big chainring which picks it up and deposits it onto the teeth. Of course, this only happens when pedaling - nothing will happen if the crank isn't rotating.

The thing is that when I try to shift up(while pedaling) the chain gets pinched and it blocks the movement of the pedals.

Welcome to the fun of front derailleur adjustment 

Sounds like you may need to make some adjustments to get the FD further out in the big gear. Probably worth checking that you got your crankset installed and aligned properly too.

If the chain doesn't shift up to the big ring but gets stuck then it's likely the high limit screw is too restrictive and the derailleur should be allowed to swing out more. If that still doesn't fix it then I don't know... it's common to have to tweak the front shifting, but for it to not shift at all is very unusual, especially with shimano chainrings which usually shift very well.
