The carbon crankarms are stiff where it matters — through the pedal stroke and into the chainring interface — while the direct-mount aero chainring profile is designed to reduce drag on setups where every watt counts. It's a natural fit for time trials, triathlons, and aero road builds where a tidy, efficient drivetrain is part of the wider speed equation.\u003c\/p\u003e\n\n\u003cp\u003eChain retention comes from the narrow-wide tooth profile, which alternates tooth width to keep the chain seated without a cage or guide — an approach that works reliably across varied terrain and cadence. The DUB spindle system uses a larger-diameter interface for improved stiffness and broad frame compatibility across threaded and press-fit bottom bracket standards. The crankset is also \u003cstrong\u003epower meter compatible\u003c\/strong\u003e, leaving the option open to add a left-side or dual-sided unit without replacing the crankset itself. Five arm lengths — 160mm through 175mm — cover the range from compact road positions to traditional fit preferences.\u003c\/p\u003e\n\n\u003ch3\u003eSRAM Force 1 Aero E1 Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eChainring: 50t direct-mount aero\u003c\/li\u003e\n  \u003cli\u003eArm lengths: 160 \/ 165 \/ 170 \/ 172.5 \/ 175mm\u003c\/li\u003e\n  \u003cli\u003eSpindle: DUB (broad BB standard compatibility)\u003c\/li\u003e\n  \u003cli\u003eRing type: Narrow-wide for 1x chain retention\u003c\/li\u003e\n  \u003cli\u003ePower meter compatible: Yes (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SRAM","offers":[{"title":"50t \/ 160mm","offer_id":44469483241516,"sku":"00.6118.740.000","price":405.0,"currency_code":"USD","in_stock":true},{"title":"50t \/ 165mm","offer_id":44469483274284,"sku":"00.6118.740.001","price":405.0,"currency_code":"USD","in_stock":true},{"title":"50t \/ 170mm","offer_id":44469483307052,"sku":"00.6118.740.003","price":405.0,"currency_code":"USD","in_stock":true},{"title":"50t \/ 172.5mm","offer_id":44469483339820,"sku":"00.6118.740.004","price":405.0,"currency_code":"USD","in_stock":true},{"title":"50t \/ 175mm","offer_id":44469483372588,"sku":"00.6118.740.005","price":405.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/sram-force-1-aero-e1-dub-crankset-3336700.jpg?v=1771293193","url":"https:\/\/ricycles.com\/es\/products\/sram-force-1-aero-e1-dub-crankset","provider":"RA Cycles","version":"1.0","type":"link"}
