Specs and photos are from Shimano's US websites (bike.shimano.com and dealers.bike.shimano.com). Component prices are Shimano's US MSRPs as listed on dealers.bike.shimano.com, confirmed at BikeTiresDirect and Competitive Cyclist. Shimano lists no price for the EW-EC300 cable, so it uses the highest regular (non-sale) price at large authorized US retailers (Competitive Cyclist $64.00; Mike's Bikes $63.99). Prices checked October 2026. Manufacturers can change specs without notice; ask us to confirm compatibility before you order.
