Bonero / Bonero Plus

mtb1299–5799 EUR

Origin

2020. The Bonero fills a specific gap in ROSE's MTB lineup — an aggressive trail hardtail with enduro-inspired geometry (65° HTA) at accessible pricing. Where the Ground Control targets XC/trail crossover riders, the Bonero is for riders who want to descend hard on a hardtail. The 140mm fork with 65° HTA was described at launch as making 'a bike that can feel like a freeride bike while being as robust as a trail bike.'
