Easton introduces EC90 SL crank
One crank to fit all road, cyclocross, and TT bikes
Published:
How about one crankset for your road or cyclocross bike that will work with a single ring, or a double, practically whatever bottom bracket standard, and still comes in at a competitively low weight? Easton just made it happen with their EC90 SL cranks.

The secret of the Cinch
On their single rings, Easton also revised the narrow/wide chainring tooth profile. They claim the updated profile optimizes chain retention, reduces running noise and minimizes friction for road and cross bikes. All good things as the latter two are much more noticeable on quieter road and cross bikes than they are on a typically louder mountain bike.
Even though the EC90 SL cranks come in at an aggressive 442g for a 172.5mm with a single 40T ring, Easton states the durability is there for nasty off-season training rides and daily commuting torture. In conjunction with the new cranks, Easton is also releasing a line of bottom brackets.
