The frame is compatible with both Shimano Di2 and Campagnolo EPS wired drivetrains and has a T47 bottom bracket. However, the 90g deficit is almost completely recovered through savings in the fork and seatpost. In terms of weight, the Koko’s 1,139g medium frame actually weighs a touch more than the same-sized disc-equipped Rere. The XXS, XS and S sizes come with a 53mm offset fork rather than 43, which presumably has been done to help reduce toe overlap. The Koko is available in a broader selection of sizing as well with the addition of an XXS size. The biggest change in geometry is the 73mm bottom bracket drop the additional 5mm drop offsets the larger volume tires. Wheelbase, stack and reach numbers also remain close to unchanged with just 4mm being added to the Koko’s headtube. Geometry-wise, the Koko shares a lot with the outgoing Rere with its 73-degree head angle and seat angle. Koko features a low-slung top tube to keep the front triangle compact and more aerodynamic (Image credit: Graham Cottingham) Specifications There is also a white colourway and a Bradley Harms Artist Edition. There is also a Limited Edition Cobalt + Green which has been inspired by the vivid blue and green colours of the Blue Spring of the Waihou River. The Essential Collection Gloss Black option we feature here has Maori design and Torquise details across the frame. In the normal position, Chapter2 still promises a comfortable ride, however, the clamp can be flipped to add an extra 8.5% more deflection if you are seeking even more comfort.Ĭhapter2’s colour options are all limited edition so when they are gone they are gone. Not only has Chapter2 spread the frame to fit a 32mm tire, but there is also a flip-able seat clamp which offers two levels of compliance. The switch from the Rere’s aerofoil downtube to a new truncated kammtail tube profile has achieved a claimed stiffness boost of 13.35% around the bottom bracket and 35.64% around the headtube for a more direct ride feel.Ĭomfort has also been added.
Chapter2 has designed this kammtail shape not only for aerodynamics but to deal with lateral stiffness loads, too.
