Frame details
Aero seat post: the aero seat tube, post and clamp from the Chase ACT 1.0 and RSP 4.0 frames help gain fractions of a second on the track and give a slightly stiffer feel.
Press Fit bottom bracket: the bottom bracket you supply has bearings in cups that press into the frame, so there are no BB threads to damage as with a traditional Euro BB.
Tapered head tube: 1 1/8" upper to 1.5" lower diameter. Run a tapered steerer fork, or a full 1 1/8" steerer fork with the 1.5" lower bearing when the headset has an optional 1 1/8" to 1.5" fork race.
Internal cable routing: the brake cable runs through the top tube for a factory look, and with no rubbing on the frame, the cable and graphics stay protected.

Please note: brake fluid that is not silicone-based can act like paint thinner and make paint peel. Do not let brake fluid touch any part of the bike.
