Its 18 inch 6061 aluminium frame blends mountain geometry with road efficiency, so one bike covers the weekday commute, the towpath and the weekend explore. Shimano Altus 21-speed gearing and Tektro disc brakes keep it responsive everywhere.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA Bike That Refuses to Choose\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePure road bikes struggle the moment the surface turns loose, and full mountain bikes feel sluggish and heavy in town. The CTM takes the middle path properly. A hand-built, press-formed 6061 aluminium frame with integrated cables stays light and responsive, Tektro mechanical disc brakes keep stopping consistent in wet or dry conditions, and an SR Suntour NEX fork with 63mm travel handles unpredictable terrain. Kenda 700x38c treaded tyres roll easily on pavement yet still grip on a dusty trail. At 14.2 kg, it stays easy to lift and store.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGo-Anywhere Hardware\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShimano Altus 21 Speed:\u003c\/strong\u003e precise, consistent shifting through integrated trigger shifters and a Shimano triple crank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTektro Mechanical Disc Brakes:\u003c\/strong\u003e responsive control regardless of conditions, from wet tarmac to muddy bridleways.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSR Suntour NEX Fork:\u003c\/strong\u003e preload adjustment and 63mm travel soak up kerbs, roots and rough patches on the route.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKenda 700x38c Treaded Tyres:\u003c\/strong\u003e cross over smoothly from trail to pavement without having to swap wheels or tyres.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCrossover Hybrid Bike Technical Sheet\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eNorthrock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eCTM Ultimate Crossover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrame\u003c\/td\u003e\n\u003ctd\u003eHand-built 6061 aluminium, press formed, 18 inch, integrated cables\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGears\u003c\/td\u003e\n\u003ctd\u003eShimano Altus 21 speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrakes\u003c\/td\u003e\n\u003ctd\u003eTektro mechanical disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFork\u003c\/td\u003e\n\u003ctd\u003eSR Suntour NEX, preload, 63mm travel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTyres\u003c\/td\u003e\n\u003ctd\u003eKenda 700x38c treaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRims\u003c\/td\u003e\n\u003ctd\u003eAlloy double wall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpokes\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChain\u003c\/td\u003e\n\u003ctd\u003eKMC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSaddle and grips\u003c\/td\u003e\n\u003ctd\u003eVelo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eH 103 x W 66 x D 178 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e14.2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003ctd\u003eAssembly tools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eFor Mixed-Surface Adventurers\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTake the cycle path to work in the morning, then detour onto a gravel trail on the way home simply because the evening is too good to waste.
