Sunday Forecaster Park 20" BMX Bike - Maca Perez Grasset Signature
Sunday Forecaster Park 20" BMX Bike - Maca Perez Grasset Signature
The Sunday Forecaster Park – Maca Perez Grasset Signature is built for riders focused on transitions, flow, and technical park riding. Designed around Maca’s style, this version combines responsive geometry with park-specific features, making it ideal for progressing in skateparks and ramps.
With a 20.5" top tube, this setup suits riders looking for a compact, responsive feel. The geometry features a steeper 75.5° headtube angle and a short 12.7"–13" rear end, keeping the bike quick and easy to control for spins, manuals, and technical park lines.
What sets the Park version apart is the inclusion of a full gyro system, allowing unrestricted barspins without cable tangling—perfect for riders learning or progressing with bar rotations. Combined with a full chromoly frame, fork, and bars, the bike is built to handle regular riding and heavier use.
Component-wise, the Forecaster Park features a sealed cassette hub and Odyssey aftermarket parts, including Path Pro tyres and the trusted Springfield brake, delivering a more dialled and reliable setup straight out of the box.
