Sunday Blueprint XL 20 (2021)

Sunday have drawn up the blueprints to one of the best beginner 20" bikes you can get your hands on. These beasts are jam packed full of the good stuff and is sure to bring ear-to-ear grins all round! These versions feature a 20.5 Inch Top Tube which is great for beginner riders who are a little bit taller and provide a shorter reach then 21" frames so the bars are a bit easier to grasp. If you kids are just staring out on 20 Inch wheels, these are a great option. With great parts like the Sunday Freeze stem and Sunday Cornerstone Grips this is a bike that's hard to pass up! To maximise grip whilst out shredding, Sunday have fitted their Sunday Current v2 2.4" Tyres which not only look spectacular but are super wide and provide great traction on a variety of surfaces. To keep the brakes working optimally, Sunday have chosen the Odyssey Quik Slic Kable to link it all together- a proven cable on BMX bikes worldwide. To further improve the braking system, Sunday have incorporated the Odyssey Springfield Callipers which are incredibly easy to set up and work really well!
