Big stopping power for big descents and big riders. With twice the pistons of previous generation Deore brake calipers, Shimano has brought 4-piston power to a much more accessible price point. This kit bundles the 4-piston BR-MT420 caliper with the BL-M4100 lever, a combination that provides excellent velocity modulation.
- I-Spec EV brake lever moves the brake lever clamp towards the stem creating an extra point of contact between the bar and the lever. The added support naturally positions your hands for a more confident grip on the brake lever and easier feathering
- 4-piston caliper is great for long descents and heavier riders
- 20% more stopping power and 150% more durable than BR-MT400
- One-way bleeding with Shimano mineral oil. System is pre-bled for easy installation
- Aluminum master-cylinder is powerful and lightweight
- Compact inline barrel reservoir
- Rotors and adaptors sold separately
- Sold as front or rear, so be sure to get the right one (or both)
