Open Up Your New Road Bike's Box

Open by slicing through the stickers covering the tabs on the top of the box, be careful to keep the box intact and hold on to the packing materials as you can use it for future shipping of your bike.

Pull out saddle/seat post and bike frame, setting aside the black owners information folder and small parts box. Remove all packaging material from the frame.

1. Install Bike Seatpost

Set the fork of your bike over edge of the box for a more stable work platform.

The seat tube is pre-greased. Slide in the bike's seatpost at least to the minimum insert line then tighten the seat post collar or close the seatpost clamp.

2. Attach Bike's Handlebars

With the fork still in the box for stability, remove stem face plate bolts and stem faceplate. Center the bike's handlebars into stem and align the faceplate. Tighten the stem faceplate bolts in a crossing pattern until they are equally tight. Maintain similar gaps between the faceplate and stem at the top and bottom as you tighten bolts.

3. Install Your Front Bike Wheel

Flip your bike upside down, balanced on its handle bars and saddle.

Make sure the tire direction is correct by using arrow direction on tires or line up the disc with the caliper. You will have one of the three types of brakes/ wheel combos. Slide in wheel then install the quick release or thru axle. Grease the threads and shaft of the quick release rod or thru axle before putting it through hub.

a. Quick Release with Disc Brakes 

b. Thru Axle with Disc Brakes

4. Install Your Pedals

The threaded pedal hole at the end of the crank arm is pre-greased. Thread in pedals as far as possible by hand. Remember the chain side pedal is reverse threaded: it screws in counter-clockwise. Tighten your pedals firmly with either a narrow 15mm wrench or 6mm allen wrench.

Double check the functionality of your bike, and rejoice, BECAUSE YOU ARE NOW READY TO RIDE!
