They fail slowly, from a fastener hole outwards, over a season of a rider braking hard against the rear edge. The load path is the reason: carbon is excellent in tension and compression and poor at accepting a concentrated point load, so every kilo arriving at a bolt is a stress riser in a brittle laminate. Spreading the same load over a surface removes the riser, which is why this component is worth more to the life of the tail than its price suggests.\u003c\/p\u003e\n\u003ch2\u003eOrder of Assembly\u003c\/h2\u003e\n\u003cp\u003eThe support goes in with the seat unit and the brackets, before the foam is fitted and before the bike comes off the stand. Once the foam is on, the fixings are underneath it. Once the bike is on its wheels, the subframe has taken its load and anything adjusted afterwards is being adjusted against that load rather than into a free position. Neither mistake is fatal, and both cost an hour that did not need spending.\u003c\/p\u003e\n\u003ch2\u003eAbout the Photograph\u003c\/h2\u003e\n\u003cp\u003eThe image shown is Carbonin's own, taken with the support in place on the machine rather than as a studio shot — this part is genuinely easier to understand mounted than lying on a bench.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003eFor the Yamaha R9, 2024 to 2026, as part of the CY20300 tail assembly.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eSupplied as a competition part without approval documentation.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Carbonin\u003c\/li\u003e\n\u003cli\u003ePart number: CY20310\u003c\/li\u003e\n\u003cli\u003eComponent: Support for the race seat unit\u003c\/li\u003e\n\u003cli\u003eMaterial: Carbon fibre, prepreg inner skin, autoclave cured\u003c\/li\u003e\n\u003cli\u003eFinish: Plane weave, buffed gloss, no clearcoat\u003c\/li\u003e\n\u003cli\u003eWorks with: CY20300 race seat unit\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha R9 (2024-2026)\u003c\/li\u003e\n\u003cli\u003eRoad approval: None supplied — closed-course competition use\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carbonin","offers":[{"title":"Default Title","offer_id":53644375851274,"sku":"CY20310","price":110.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/CY20310.png?v=1788854932","url":"https:\/\/inter-pace.com\/en-gh\/products\/carbonin-carbon-seat-unit-support-yamaha-r9-cy20310","provider":"Inter-Pace","version":"1.0","type":"link"}
