Gravel Grinder News: Shimano CUES Drop Bar Components

As expected when Shimano released the CUES flat bar parts, a drop bar lever for CUES has now been revealed. We first got wind of the parts last year, which I talked about in this FN&V.

Featuring hydraulic and mechanical brake Dual Control Lever options, along with "dummy" levers for 1X set ups, this group stands to become one of the more popular, affordable choices for gravel riders. 

These levers will be available for 9,10, and 11 speed set ups, but like their flat bar siblings, CUES has its own cassette spacing and lever pull ratios so these cannot be mixed and matched with any other current Shimano 9,10, or 11 speed components. 

However; you can mix and match within the CUES ecosystem. So, say for instance that you had purchased a 10 speed CUES flat bar bike and then got a sweet deal on a drop bar frame for gravel. One could just buy the Dual Control Levers, use the rest of the CUES flat bar parts, and save a little coin.

CUES drop bar will also have 1X and 2X options for crank sets. In 2X they will offer 50/34 and 46/32 options using HollowTech, two piece design. In 1X there will be a 42T and a 40T option in HollowTech along with a heavier, hot forged two piece model with the same chain ring options. 

Brakes, cassettes, and rear and front derailleurs are all similar to the current CUES offerings with the addition of a braze-on style mount option. Both new front derailleurs are optimized for their companion crank sets. 

Essa 8spd: It should also be noted that a drop bar lever set for Shimano Essa has also been introduced, albeit in just a 1X configuration. Essa is compatible with previous Shimano 8spd parts. 

Comments: This is great news for those who want lesser expensive alternatives to 11 and 12 speed groups and should satisfy many folks in terms of look and feel. 

There have been some reports that I have seen with issues with  CUES rear derailleurs not operating correctly. This may be due to some manufacturing issues, so it is hoped that those things can, or have been addressed. It is also notable here that CUES uses LinkGlide cogs and chains which prioritize shifting precision, and not speed, so instantaneous shifts are not going to happen within the CUES range.

CUES as a concept is valid, but in its implementation it finds some push-back from those in the cycling community. It would appear that the incompatibility with anything else Shimano has out is part of this. But when you think about things, Shimano had to make some kind of call on spacing/shifter ratio. They either had to use nine, or ten, or eleven standard, and then in terms of 10 and 11 you have the difference between MTB and road ratios, which are different as well. 

So, what did you think Shimano should have done? They decided to circumvent all the choices and made a call to make one that fit their intentions. I totally get it, and it does make sense. The wish for a "backward compatible 9/10/11 groupset" is a pipe dream. 

What concerns me more are the reports of rear derailleurs that are not up to snuff in terms of precision or durability. One would hope that Shimano will, or has, addressed this. 

If the rear derailleur issues are behind Shimano with regard to CUES, then this is an exciting development.
