Direct swap, no fuss, relatively easy to install, though i’m experienced in that department, i think most capable diy’ers with a decent bike tool kit could do in under 2 hours including necessary maintenance with hub bearings etc. For the money, excellent combination. Sunrace will replace my other bikes sram cassette when it finally wears out. Range of gears also very good even with a 34t up front, the steep bits may be a struggle if your legs aren’t up to it, maybe a 32t is better suited to your needs if this is your thing. Personally i prefer a speedy combo rather than a climby one. Couldn’t find a better alternative at this price point, seller was speedy, same day in fact for me. Don’t know how they do it so well. Bravo. Review: Fake advertising - The M5100 shifter was advertised with a gear display however the one I received did not had that feature. Shifters with a display is something I look into when getting a bike as I find it useful for me. I haven’t installed this yet so can’t give a word of mouth how it performs but so far it looks like top quality shimano parts. Just a bit disappointed by the shifter ## Features - 🚴‍♂️- Best deal, 11 speed has been an essential in MTB and 1x single chainring has been a trend for lightweight and wide ratio.

Replace the entire wheel with something compatible. Make sure the axle spacing matches your frame. You will also need to make this a 1 x 11. If you want to do a 2x11, get the option with the 11-42 tooth cassette. If you opt for the 2x11 , I would recommend the removal of the outer chainring, replace it with a chain guard to take up the outer step on the spider and protect your calf. This will give you a 32x11 top gear and a 22x46 low gear (I am assuming your crankset is a 22/32/42). If you opt for the 1x, you should just get a new crankset. An inexpensive one with a square taper should do the trick. I would suggest a 28 to 32 tooth front sprocket. Your choice depends on the terrain you plan to ride and your fitness. I noticed a response that says you need an XD adapter. I do not think this is the case. Get a Shimano 10/11/12 compatible hub and this cassette should slide right on. **Q: sirve para reemplazar 3x10 en fuji nevada 1.1 2013?** A: Yes, it can. **Q: Does this work with a 2004 Santa Cruz Heckler; the ones with the weird derailleur hangers?** A: yes, it is an easy upgrade **Q: What chain do you recommend for this cassette ?** A: must use any 11 speed chain and 116L long. thanks.
