Buying Guide
- Wheel compatibility: Confirm whether the frame supports 27.5, 29er, or both, and check tire clearance for your preferred width (commonly up to 2.25″).
- Axle standards: Decide between QR 135/135mm, 142mm, or 148mm thru-axle configurations, keeping in mind stiffness, rigidity, and compatibility with your fork and rear hub.
- Headset and bottom bracket: Verify headset size (42/52mm tapered) and bottom bracket type (BB92 or press-in) to ensure compatibility with your components.
- Internal routing: Internal routing provides a clean look and protection for cables; ensure your internal routing is compatible with your shifter and derailleur cables.
- Frame weight vs. strength: Carbon frames offer high stiffness-to-weight ratios but can be pricier; assess riding style (XC vs. trail) and budget when selecting a frame.
- Sizing and fit: Choose sizes (15″, 17″, 19″, etc.) that align with rider height and reach. Consider seat tube length, stack, and effective top tube for a comfortable position.
- Maintenance and warranties: Check manufacturer warranty terms for carbon frames and recommendations for suspension and drivetrain compatibility to maximize longevity.
