SRAMDUB

I bought the entire GX groupset minus the cassette individually, because I wanted use an NX cassette so I didn't have to replace my hub to XD. Installed all the components and everything works superbly.I had no install issues because I did the necessary research and measurements. You should know your bottom bracket type and measurements, if you are boost or non-boost, which spacers you use and where (all information is available at SRAM) take a digital caliper and measure. Just make sure you watch the videos how to install these products before you purchase the components and try to install the wrong one. Be sure you have a new high quality derailleur hanger. This is not a first time beginner undertaking. Know when you have no idea and ask someone and if you don't know or don't have the right tools, take it to a bike shop. You will need a chain whip, and the right socket and tools to remove your existing cassette, and bottom bracket, and same for installing your bottom bracket. I used an SRAM DUB BSA boost+ bottom bracket 68/72mm. I lucked out because it had the correct spacer for the right side, plus the boost spacer I didn't need.

One side of the BB was missing on arrival

The swap from the old to the new was easy. Watched a few youtube videos, ordered my 12 point socket, got some park tool performance grease on Amazon and it took about 1.5 hours. Get all your torque specs first and make sure if you have a click torque wrench that it clicks on the counter clockwise direction. Mine didn't and i had to use an old tension bar style that works in both directions. Eliminated a lot of creaks while riding. Easy swap. Also used a small paint brush to apply grease to the inside of the bottom bracket.

Se requiere del torquimetro para un correcto apriete, es el segundo bottom bracket dub que instalo, no se desajusta y es de alta durabilidad.

Like the easy way to install. The new crank move smoothly, help indeed with the new Sram GX cranks.
