Full disclosure: I have not purchased or used this item (generally bad taste, but this is good info to know)

Helmets are smooth plastic on the outside for a reason, to be able to slide along the ground in event of a crash. By putting this rubberized cover on, you can risk having the material snag on the ground and possibly tweaking your neck the wrong way. Which is generally considered bad. Just a general warning y'all.

Same Quarq reliability
5 5

I've owned or had experience with every power meter on the market and theres no beating the value, reliability, accuracy, or weight that Quarq offers.

Sure, there are cheaper single arm power meters, but all they do is double the power on the left side. If you pick one up without knowing of a possible leg imbalance (I personally have a 54:46 split because of a past injury), your power numbers may be 10% high or low, which negates their claimed 2% accuracy.

Quarqs also have a proven track record. Many of the newer companies out there have only had their product out for a few years, and many are on their second or even first versions of public release units. The DFour91 is the culmination of 10 years of technology at Quarq, and it is their third major release, fixing a few small issues that were present on the previous Elsa and Riken.

The DFour91 has a +/-1.5% accuracy which means you can trust your power numbers. I've used other power meters in the past which claim +/-2%, but all their numbers have always seemed at least 5% off from my Quarq numbers. The last thing you need when you are training is to not be confident in the data you have, it just takes away one more variable.

If you want to get your drivetrain shiny clean, this is the brush you'll want. The super stiff bristles agitate any sort of grease and grime off your gears. Obviously in conjunction with degreaser though. I find that if you do attack a particularly greasy part, the bristles will become impregnated with grease and you'll want a new brush after that. That applies for anything though.

I never thought I would be reviewing rubber gloves, but here I am. I used to try and be a macho man, getting my hands black with grime every time I worked on my bike. Then I realized nobody really cares and girls don't like dirty nails. So I bought some gloves. As all the other reviews say, they are a nice thickness and even reusable if you wish.

ugly duckling that grows on you
5 5

When R9100 was first announced, I thought it was by far the ugliest group set on the market. Most people still think this, but the wide arm design has grown on me. In line with the rest of the group, its not really much of a revolution as just a small evolution. As always, the chainrings on the crank really are the shining star. Cold forged and filled with injection molded carbon fibers, they are both ridiculously stiff yet super light. They did change the spacing of the rings slightly, but they are realistically compatible with any 11 speed groupset.

Superior ergonomics, flawless smoothness
5 5

Shimano has redefined mechanical shifting once again. Ergonomics are absolutely top notch. If you're moving over from a 10 speed or earlier group, the levers are longer so you may have to move to a shorter reach bar or shorter stem though. The small shift paddle is now enlarged to make them easier to reach in the drops. The hoods have a new texture which honestly doesn't make a difference for me, but they look cool at least? The action is ridiculously tight and smooth, it reminds me of my other favorite past time.

Another note is that it is compatible with all 11 speed Shimano derailleurs (5800, 6800, 9000, R8000, obviously R9100). All the necessary cables and housing is included with the shifters.

Super slick
5 5

My god, this is lighter action than the newest Di2 shifters honestly. I sometimes don't even realize I have shifted! The new Shadow design means there is more chain wrap around the cogs for faster shifting. It also means easier wheel changes. Some people have said it was actually quite a bit more difficult to get their wheel out, so I was apprehensive before actually installing the stuff, but I found it marginally easier as the derailleur is tucked behind and out of the way. It also allows you to go up to an 11-30t cassette now, which definitely makes the difference after a long day in the saddle. The install is a little bit different than before, but at the end of the day its still just two limit screws, a barrel adjuster, and B-tension adjust. Nothing too dififcult if you know what you're doing. You will need a little piece of very flexible housing, either the included segment or a segmented system, like the Alligator iLinks I'm using.

Another note is that it is compatible with all 11 speed Shimano shifters (5800, 6800, 9000, R8000, obviously R9100).

Flawless shifting
5 5

Honestly I don't really see the need for Di2 with the newest generation of Dura Ace. The front shifts are so ridiculously flawless, the only thing you're missing is the auto trim. The setup is nothing like previous designs (nor any other front derailleur from any other manufacturer), so definitely study YouTube for a good setup video if you're a home mechanic. The new design alleviates the need for an inline barrel adjuster, so it tidies the front end up real nicely.

Another note is that it is compatible with all 11 speed Shimano shifters (5800, 6800, 9000, R8000, obviously R9100).

Great braking, great hubs
5 5

First of all, the weight. My set weighed in at 1,266.4g including rim tape (544.4g front, 722.0g rear). As far as I know, that makes it the lightest stock tubeless wheelset on the market.

Some of you may be apprehensive about carbon braking, but no need to fear. The rims are actually just rebranded Reynolds Attack rims (they actually have a Reynolds logo on the rim as well), and combined with their Power pads, they actually have a higher initial bite than alloy brake tracks. Total power once you really get down in the lever is about the same, but the bite definitely inspires confidence. Do note that this is for dry braking, I haven't been caught out in the wet yet, although other folks have said the wet braking is also really top notch.

Next is the hubs, although i9 doesn't have the same cachet as DT Swiss or Chris King, those folks over in Ashville, North Carolina definitely know what they're doing. Obviously US manufacturing doesn't always mean best in the world, but in this case, they really take it with pride. There is no preload system to mess around with, they just work. They roll on high grade Enduro bearings with no special proprietary sizing. A full bearing kit for the front and rear is actually sold for only $60! The rear is also laced 2:1, which means there are 16 spokes on the drive side, 8 on the non drive. This means the tension is pretty much equal on both sides, which leads to a more balanced wheel. The 16 drive side spokes also lead it to have the stiffness of a 32 spoke wheel (in theory). I don't weigh enough to flex them much (125 lbs/56.5kg), but they do definitely feel more spritely than most other wheels I have ridden.

Compatible with tires anywhere from 21 to 35mm, they're a super versatile wheelset that will take most anything that you can throw at them. They also do ship with tubeless tape installed, so if you want to try that weird stuff, its an easy setup as the rim does have bead shelves for easier tubeless tire inflation. Compatible with everything from 8-11 speed with the included spacer. Small note is that skewers are not included.
