## Description

11 speed mtb groupset 4pc

Review: Great paets bundle! - Great parts bundle, easy to do a build!
Review: Great upgrade package - I upgraded my 7 speed cassette to get lower gears for trail rides and after some research came across this package. Only thing you need is to replace the hub and resize the chain but everything else is taken care of. Shifting is crisp, smooth and now my bike keeps up with everyone else. Price for the kit is reasonable and quality is great - I highly recommend

## Features

- 🚴‍♂️ The complete 11-speed groupset consists of four components, designed for compatibility with Shimano M5100: the right shift lever (SL-M5100-R, available with or without a display), the long cage rear derailleur (RD-M5100-SGS), the large cassette (CS-M5100-11, 11-51T), and the 11-speed chain (HG601).
- 🌟 This groupset can upgrade or replace standard 8-, 9-, and 10-speed MTB setups with an HG-spec rear hub. The 51T large cassette, when paired with a single-speed crankset, enhances both lightweight performance and efficiency.
- 🎁 JGbike retail packaging comes ready for installation right out of the box. It is suitable for upgrading and replacing drivetrains on most professional and non-professional mountain bikes, including XC, trails, and downhill. Upgrading the drivetrain enhances the riding experience and allows the bike to perform at its full potential.
- 🏫 Most users aim to upgrade and replace the OEM entry-level drivetrain on their bikes, including stock systems on youth bikes. They seek improved performance while ensuring long-term sustainability for future maintenance and replacements.

## Questions & Answers

**Q: i have a 7 by 3 21 gear drivetrain right now. what do i have to do to figure out if this will work on my bike?**
A: The cassette will not fit on a 7-speed hub. 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. KMC/shimano/sram whatever,
