Engineered for e-MTB strength, so you don’t need to worry about pedal strikes or holding back on your next gravity run. Forged aluminum arms keep you confident on the trail, while alloy self-extracting crank bolts mean efficient routine service and minimum added weight. Added details like pedal washers, molded impact boots, and e-rider preferred shorter lengths deliver all the high-end features you'd expect from a crankset, well over its price.\u003c\/p\u003e\n\u003cp\u003eHelix Core e*spec Cranks are available in 24mm ISIS for a variety of popular motor systems, or 30mm ETOR for Fazua Ride 60. \u003c\/p\u003e\n\u003cp\u003eCranks for ISIS Spindle Motor Systems are available in 21.5mm and 26mm offsets to customize fit, Q-factor, and ride feel. \u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e26mm offset cranks are optimized for Bosch CX Gen4\/Gen5 motor frames, but will fit on all ISIS spindle motors. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e21.5mm offset cranks are designed for optimal fit with Bosch SX, Brose S-Mag, Avinox, TQ HPR50 and \u003cmeta charset=\"utf-8\"\u003eSpecialized 2.2 \u0026amp; 3.1\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ethirteen","offers":[{"title":"Bosch SX \/ Brose S Mag \/ TQ HPR50 \/ Avinox \/ Specialized 2.2 \u0026 3.1 - 21.5mm Offset \/ 155mm","offer_id":45671707902269,"sku":"CS5ESA-100","price":75.95,"currency_code":"GBP","in_stock":true},{"title":"Bosch SX \/ Brose S Mag \/ TQ HPR50 \/ Avinox \/ Specialized 2.2 \u0026 3.1 - 21.5mm Offset \/ 160mm","offer_id":45671707935037,"sku":"CS5ESA-101","price":75.95,"currency_code":"GBP","in_stock":false},{"title":"Bosch SX \/ Brose S Mag \/ TQ HPR50 \/ Avinox \/ Specialized 2.2 \u0026 3.1 - 21.5mm Offset \/ 165mm","offer_id":45671707967805,"sku":"CS5ESA-102","price":75.95,"currency_code":"GBP","in_stock":true},{"title":"Bosch SX \/ Brose S Mag \/ TQ HPR50 \/ Avinox \/ Specialized 2.2 \u0026 3.1 - 21.5mm Offset \/ 170mm","offer_id":45671708000573,"sku":"CS5ESA-103","price":37.93,"currency_code":"GBP","in_stock":false},{"title":"Bosch CX Gen4\/5 \/ Brose S Mag - 26mm Offset \/ 155mm","offer_id":55309270155646,"sku":"CS5HSA-100","price":75.95,"currency_code":"GBP","in_stock":false},{"title":"Bosch CX Gen4\/5 \/ Brose S Mag - 26mm Offset \/ 160mm","offer_id":55309270188414,"sku":"CS5HSA-101","price":75.95,"currency_code":"GBP","in_stock":false},{"title":"Bosch CX Gen4\/5 \/ Brose S Mag - 26mm Offset \/ 165mm","offer_id":55309270221182,"sku":"CS5HSA-102","price":75.95,"currency_code":"GBP","in_stock":true},{"title":"Bosch CX Gen4\/5 \/ Brose S Mag - 26mm Offset \/ 170mm","offer_id":55309270253950,"sku":"CS5HSA-103","price":37.93,"currency_code":"GBP","in_stock":false},{"title":"Fazua Ride 60 \/ 155mm","offer_id":45671708033341,"sku":"CS5ESA-104","price":84.95,"currency_code":"GBP","in_stock":true},{"title":"Fazua Ride 60 \/ 160mm","offer_id":45671708066109,"sku":"CS5ESA-105","price":84.95,"currency_code":"GBP","in_stock":true},{"title":"Fazua Ride 60 \/ 165mm","offer_id":45671708098877,"sku":"CS5ESA-106","price":84.95,"currency_code":"GBP","in_stock":true},{"title":"Fazua Ride 60 \/ 170mm","offer_id":45671708131645,"sku":"CS5ESA-107","price":41.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5971\/7693\/files\/CS5ESA-105_04-Square_f1e3b80c-30cf-4f30-b59c-d943a54948f4.png?v=1737626720"},{"product_id":"helix-race-carbon-e-spec-crank","title":"Helix Race Carbon e*spec Cranks","description":"\u003cp\u003eHelix Race Carbon e*spec Cranks represent the pinnacle of ultralight carbon e-bike crank design, the highest strength-to-weight available, for All-Mountain applications.\u003c\/p\u003e\n\u003cp\u003eThrough years of development and refinement in carbon layup and molding, we've honed the Helix Race Carbon e*spec cranks to deliver the highest strength-to-weight ratio crankset in the e-MTB world.
