The RX610 lever handles shifting duties with an ergonomic profile designed for comfortable hand placement across long hours in the saddle — reach adjust and an anti-slip texture let you dial in the fit regardless of conditions. It's also at home on flared drop bars, which makes it a natural choice for riders who prioritize control on rough descents and loose surfaces.\u003c\/p\u003e\n\n\u003cp\u003eBraking is handled by the RX400 flat mount hydraulic disc caliper, a two-piston unit that delivers consistent stopping power with good heat dissipation — useful when loaded gravel descents are on the agenda. The hydraulic system keeps lever feel predictable whether you're on pavement, hardpack, or something muddier. Sold as individual front-left and rear-right units, so you can replace or upgrade one end without buying more than you need.\u003c\/p\u003e\n\n\u003ch3\u003eShimano GRX RX610\/RX400 Shift Lever Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e 12-speed GRX drivetrain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrake type:\u003c\/strong\u003e Hydraulic disc, flat mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliper pistons:\u003c\/strong\u003e 2-piston (RX400)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLever features:\u003c\/strong\u003e Reach adjust, anti-slip texture\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBar compatibility:\u003c\/strong\u003e Designed for use with flared drop bars\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black \/ Front \/ Left","offer_id":43520173113388,"sku":"IRX6101DLF6SC100A","price":339.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ Rear \/ Right","offer_id":43520173244460,"sku":"IRX6101DRRDSC170A","price":339.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-grx-rx610rx400-shift-lever-and-brake-set-3558197.jpg?v=1771297813","url":"https:\/\/ricycles.com\/products\/shimano-grx-rx610-rx400-shift-lever-and-brake-set","provider":"RA Cycles","version":"1.0","type":"link"}
