We like these sprockets as they save about 400-500g over a lightweight steel or a twin ring sprocket and cost half of a twin ring.

Saving this amount of weight on the rear wheel makes a real difference to grip due to its significant unsprung weight saving meaning the suspension can react faster maintaining traction.

They are hardened alloy and last about half to 2/3 as long as a steel sprocket in real world testing, so aside from having to change it more often there is only a net benefit running these sprockets.

For Hard Enduro use we recommend for

TPI: 12t front 50t rear

TBI 12t front 47/48/49t rear (45 is stock and good for green lanes(13 or 14 front) or XC (13 front)
