Sunday 2021 High C 23.5″ TT 29er Gloss Sunrise Fade



Sunday designed the High C 29″ with a 100% Full Chromoly Frame, Fork, and Bars, in order to make it one of the most reliable 29″ bikes on the market.

Whether it’s cruising all day, jumping curbcuts, or wheelie-ing around, this bike is intended to handle it all. The frame has a unique shortened rear-end geometry compared to most bikes on the market of this size to make it easier to handle and manipulate in tough positions.

The frame has bottle cage mounts if someone feels like strapping any of their favorite beverages to the bike for an adventure and is spec’d with some dialed parts from Odyssey, Maxxis and FSA.

Sunday took the continued success of the Model C and borrowed some characteristics of the Fairdale Taj to make something that Sunday’s truly proud of. That is Sunday’s perspective on the High C. We hope you dig it!

We are proud to introduce our 2021 Sunday complete bikes. You’ll quickly find that our new line is full of improvements once again this year. We are excited to introduce “Park” models in both the Primer and Forecaster categories. With a model-specific geometry that features accents like a lower standover height and an Odyssey Gyro kit with dual cables top and bottom, both the Primer and Forecaster Park models are built to shred right out of the box.

We are also happy to announce that Broc Raiford recently joined the Sunday Pro Team and we were able to include his signature Forecaster complete bike in the 2021 line. Additional improvements can also be found on our popular High-C 29er bikes. This year’s model features V-brakes, an Avid brake lever, a quick release seat post clamp for 27.2 posts, a revised gear ratio and an all-new handlebar design.

From our entry level 16” Blueprints to our 100% aftermarket Soundwave Special, the entire 2021 line features the vibrant colors and finishes that Sunday is known for and, as always, you can count on the durability, manufacturing quality and modern spec that has made Sunday the go-to brand for riders shopping for a new complete bike. We hope that you’ll enjoy checking out the new Sundays as much as we enjoyed making them. Thank you for your continued support!
