- Mounting compatibility: Check caliper spacing (74 mm and 51 mm are common) and handlebar compatibility (22 mm clamps are standard for many kits).
- Kit completeness: Look for included rotors, bolts, and pads. Some kits include pad adjusters or gap regulators for easier setup.
- Intended riding: Choose based on riding style—trail and enduro riders may prefer hydraulic systems, while casual riders can opt for mechanical kits for simplicity and cost.
FAQ
- What rotor size should I choose? Most bikes use 160 mm rotors; check frame clearance and caliper mounting to avoid rubbing.
- Are these kits compatible with all bikes? Most are designed for a wide range of MTB, road, folding, and urban bikes, but always verify caliper spacing and handlebar size.
- Do I need special tools? Mechanical kits require standard bike tools; hydraulic kits may need bleeding Equipment and more precise alignment.
- Can I install a hydraulic kit myself? Yes, with careful following of instructions, but consider professional help if you are unsure about bleeding and alignment.
