Quill Oval Stainless

THE Quill looks like it will retain its looks over the years and the makers are obviously confident because they offer an 18-month warranty and lifetime corrosion guarantee. Sleeve options include carbon and rainbow titanium costing up to £299. There’s a high-level version for selected bikes, too. Quill claims a 6bhp gain and it’s not road-legal.
