It's the pick if you've already decided on carbon and just need to choose open versus closed back.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTalk Nerdy To Me\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTriRig lays this cup up from genuine carbon fibre rather than ThermoPlast, and despite the material upgrade it still lands at a claimed 365 grams per set, running over 200mm long with the same textured neoprene pad to hold your elbows steady through long efforts without feeling bulky under your arms. Mounting matches the rest of TriRig's arm cup range: two fore-and-aft bolts into threaded bosses using the included M5 and M6 hardware, fitting most aerobars including TriRig's own Alpha One, with optional Wingspan Extenders for a non-standard hole pattern. The Open Back SL Carbon variant specifically isn't recommended for a Trek Speed Concept Gen 3 from 2022 onward, so check your frame before ordering if that applies to you.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFast Facts\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- Genuine carbon fibre construction\u003c\/p\u003e\n\u003cp\u003e- 365g per set\u003c\/p\u003e\n\u003cp\u003e- Over 200mm long, textured neoprene pad\u003c\/p\u003e\n\u003cp\u003e- Mounts via two fore-aft bolts, M5\/M6 hardware included\u003c\/p\u003e\n\u003cp\u003e- Fits most aerobars including TriRig Alpha One\u003c\/p\u003e\n\u003cp\u003e- Not recommended for Trek Speed Concept Gen 3 (2022+)\u003c\/p\u003e","brand":"TriRig","offers":[{"title":"Open Back","offer_id":48045871988913,"sku":"AID-850035164204","price":533.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0576\/7659\/5377\/files\/TriRigCarbonArmcupOpen1.webp?v=1792473972","url":"https:\/\/aidstation.com\/products\/tririg-carbon-arm-cups-open-back","provider":"Aid Station","version":"1.0","type":"link"}
