 | | 2007 Shimano XTR FH-M975/M970 Rear Hubs |
Day seven of the 2007 XTR component review and pricing preview. We follow up yesterday's front hubs with the new XTR rear hubs. Again, no huge departure here, just continuous refinement. The already legendary seals have been improved and now a 14mm 7075-grade alumium alloy axle for increased stiffness. Also of interest is the new 36 point engagement freehub for faster engagement. The disc version stays with the lightweight, patented center lock system. ETA is early October so we are keeping an eye out and will let you know as soon as we have them.
FH-M975/M970: Rear Hubs
The new XTR rear hubs offer improved performance any rider will appreciate. A quicker engaging freehub body, improved durability and increased rigidity are included in a disc & non-disc XTR rear hub:
• Titanium Freehub body:
Quicker engaging: With 36 engagement points, pawl engagement is 125% quicker than current XTR. The new freehub body has a 10° maximum engagement angle for the ultimate combination of low friction and quick acceleration.
• Improved seal design:
Based on Dura-Ace’s improved seal design & internal grease sleeve, durability is improved while service intervals are extended.
• 14mm axles:
The 7075-grade alloy axle improves rigidity by 40%. The new axle design also makes serviceability easier through the use of one cone wrench and a 5mm Allen wrench.
• Angular Contact Bearings:
A serviceable sealed bearing assembly that handles both vertical and lateral forces exerted by the wheel.
