Chain and Cassettes: cramming in 11

The new cogs are the same width as the 10-speed versions; they’re simply closer together. Chains, therefore, also retain the same width rollers. Only the outer plates of the chain are thinner. The outer plates are also now solid, instead of relieved like on Shimano’s current chains. Also gone is the need to orient the chain directionally.

Thanks to the retained cog and roller width and a new PTFE coating on the entire chain, durability should be similar to 10-speed versions. Cassette offerings include 11-23, 11-25, 11-28, 12-25 and 12-28.

Pedals: more fit options

Shimano will offer its popular Dura-Ace SPD-SL road pedals with a 4mm longer spindle. This will help many riders who currently use pedal spacers or a different pedal system. The axle will also be available as an aftermarket part, but the cost will be high when compared with buying a new set of pedals.

Shimano will also begin offering a third cleat option. The new, blue cleat features “front center pivot” float, rotating at the nose of the cleat instead of centering the float over the pedal body. The blue cleat has less float and doesn’t shift laterally like the current yellow cleat. The fixed red cleat will remain available. Shimano will also offer shims to help bike fitters accommodate leg length discrepancies.
