Sunday Primer Park 20" BMX Bike Description:

The Sunday Primer BMX Bike falls closer to the entry-level end of the Sunday lineup while still being based around modern, pro-level geometry and styling. Although aimed more towards beginner riders, this bike still offers chromoly 3-piece cranks within a sealed bottom bracket, a sealed cassette rear hub, and equipped with several Odyssey components. Get out and surf some ramps with this surf blue beauty!

Note: This is the 20.5" toptube version of the Primer model.

Note: To ensure that every component on your bicycle is working properly, Dan's Comp recommends that all bikes be assembled by a qualified mechanic.
