Sunday Primer Park 20 (2021)

If you are looking for a great bike at a great price point- look no further! The Sunday Primer's are stacked with epic parts and look super clean and dialled. This bike is equipped with a gyro system so you can spin the bars or whip the bike around without those pesky cables getting all tangled up! To beef up the bike, Sunday have decided to throw on a couple of Odyssey Path Pro tyres in 2.4" These wide-guys give you loads of grip and they are from Odyssey- so you know they are top quality. Keeping with the Odyssey theme, Sunday have bolted on the Odyssey Springfield Brake to ensure your skids are absolutely epic. These brakes are also super easy to adjust which is definitely a plus! The Sunday Cornerstone grips are comfy and stylish and the chromoly 3-piece cranks are a must for anyone looking at shredding! The Primer is a serious starter bike at a seriously great price.


Built around a pro-level geometry in a range of top tube sizes, the Primer is spec’d with quality parts like Odyssey Springfield brakes and Path Pro tires. The 2021 Primer also includes a fully sealed rear cassette hub and proven parts like the Sunday Freeze Stem and an FSA Headset.
