2 in 1 Crank Arm Cap Removal Installation Tool, Crank Adjusting Cap Tool for SRAM Dub, Shimano XTR M9100 Crank Arm Dub Cap, Bicycle Crank arm Bolt Tool, Bike Crank Extractor

The Danuosi cap remover is a very specialized tool for a particular job, but when you need it, you have few options. I like that Danuosi thought to imprinted the tool with "Remove →" to remind the user that the cap is reverse-threaded. And I like that they thought to make the tool usable with an 8mm hex key, since removing the cranks requires the same tool.I managed to get the cap off eventually, but it was a balancing act to apply adequate torque. Several times, something-or-other slipped and the pins dislodged from the cap. Next time, I might lay the bike down on the ground instead of having it in wobbly bike stand.The pins on the tool are 0.100" diameter, but the holes in the cap look to be about 0.125" at the opening. The job might have been easier if the pins were a bit longer, or if they were closer to the diameter of the holes. There's another brand of this tool whose pins are conical at the base, and seems like it might mate better with the cover.Anyway, this got the job done. (disclaimer: I'm not a bike mechanic)

Tool doesn’t resist required torque damaging tool and cap

the fit does feel a little bit "sloppy" when putting the pins from this socket into the dub cranks. After a bit of trying to figure out my best positioning and angle for this to work I was able to get the cap off. I think my complaint here lies with SRAM, it's not the greatest design IMO.Having the direction for removal screened on is welcome to see. Would have been better if it were etched in but for how many times most people (ie home bike mechanic) will use this tool it's not a big deal.Overall this is a good alternative for a home bike mechanic not wanting to spend more $ on a higher end version of this tool.

I like to do my own maintenance, and having just purchased a bike with the SRAM DUB, I went on the search for the specialized tools needed.I found this tool worked well, cleanly engaging the four pins on the crank cap. I like that the tool is marked with the correct direction to remove the cap, because mine were particularly tight... and since they're a left-handed (reverse) thread, you don't want to be reefing on things in the wrong direction. Installation afterward was also a breeze.One note is that you can use either a 3/8" ratchet or an 8mm hex key with this tool. I prefer the ratchet, as I think the ergonomics are better, but since you're going to need the 8mm hex key to remove the crank arm anyway, that's a way to require one less tool from the drawer.

First time I tried to use it The pins barely engaged in the cap and when I finally were able to get some force on it all the pins bent

Nice tool. Just what I needed for one of my bikes. Definitely didn't want to use a pin spammer on the DUB.My only complaint is that there is an identical product for a little less. I mean these are exactly the same, right down to the 1/10th of a gram. This tells me they have used the same engineer(s) and manufacturing facility, or that both companies with the same parent company. Am I being too picky?I recommend this tool, good quality, good price.

This has worked amazing so far it is a perfect fit for my dub headset. It looks to be very high-quality. It is anodized aluminum i believe. High quality overall. It fits on a 3/8 ratchet and it is perfect for anyone working on a bike, trying to get a crank set off or on. A+ would recommend to anyone!
