{"product_id":"ochain-e-emtb-chain-damper","title":"Ochain E eMTB Bosch Gen 5 Chain Damper","description":"\u003cp\u003eOchain replaces the spider on a mountain bike crankset to remove the direct link which transfers suspension force to the riders feet, resulting in less fatigue and improved suspension performance. A bonus of the Ochain is reduced drivetrain noise as the chain is no longer active when the suspension moves.\u003c\/p\u003e\n\u003cp\u003eThe \"E\" Version of the Ochain is internally adjustable to vary the amount of decoupling between the chainring and the cranks. Out-the-box, it is set to 9 degrees, but can be changed to 6 or 12 degrees.\u003c\/p\u003e\n\u003cp\u003eThe next-generation spider design allows the chainring to rotate backward, effectively decoupling the rider from pedal feedback forces. This reduces chain turbulence and drivetrain noise, creating a quieter, more stable ride while allowing riders to stay focused on the terrain ahead.\u003c\/p\u003e\n\u003cp\u003eBy improving stability while braking and cornering, Ochain R enhances control on rough and technical trails. The external travel adjustment system enables precise tuning of drivetrain behaviour, allowing riders to select the amount of rotational travel to suit terrain, riding style and bike setup. Mounted directly to the crankset, the system delivers consistent performance regardless of cassette gear ratios. The latest generation also features improved impact resistance and enhanced sealing for increased durability and contamination protection.\u003c\/p\u003e\n\u003cp\u003eFeatures\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpecific eMTB version of the spider system that decouples pedal feedback from the drivetrain\u003c\/li\u003e\n\u003cli\u003eExternal travel adjustment with selectable travel settings\u003c\/li\u003e\n\u003cli\u003eImproves stability while braking and cornering\u003c\/li\u003e\n\u003cli\u003eReduces chain noise and drivetrain turbulence\u003c\/li\u003e\n\u003cli\u003eRe-engineered design for improved impact resistance and durability\u003c\/li\u003e\n\u003cli\u003eEnhanced sealing for better contamination protection\u003c\/li\u003e\n\u003cli\u003eCompatible with Bosch BDU38 (Gen 5) \u003c\/li\u003e\n\u003cli\u003e104 BCD chainring compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMinimum chainring size: 32T\u003c\/li\u003e\n\u003cli\u003eCompatibility: \u003cspan class=\"*:tw-text-slate-950\"\u003e Bosch BDU38 (CX Gen 5)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eChainring compatibility: 104 BCD\u003c\/li\u003e\n\u003cli\u003eTravel settings: \u003cspan class=\"*:tw-text-slate-950\"\u003e9° factory setting, adjustable to 6° or 12° using included chips\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eService interval: 100 hours elastomer replacement, 200 hours full service\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ochain","offers":[{"title":"Bosch Gen 5","offer_id":57994740269440,"sku":"OC8795000","price":280.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0430\/6570\/4600\/files\/ochain-e-emtb-chain-damper.jpg?v=1777452376","url":"https:\/\/20twentystore.com\/products\/ochain-e-emtb-chain-damper","provider":"20TwentyStore","version":"1.0","type":"link"}
