Installation

• Scope of This Assembly Guide
  • This manual is intended as a guide for the assembly of the Yoeleo G21 Disk from a frameset to a complete bike.
  • Due to the high degree of complexity of the Yoeleo R11 Disk this manual is intended for expert mechanics of Authorized Yoeleo Dealers.
  • Please utilize Authorized Yoeleo Dealers for assem-bly, service, repairs, or maintenance performed on the Yoeleo products or your trusted local bike shop who work frequently with internal cable routing bikes.
• General Notes on Assembly
  • Before assembly inspect all components (frame, fork, seatpost, handlebar, headset top cap and spacers) to ensure that there aren’t any sharp edges, burrs, or cracks.
  • In the case of any crack, DO NOT continue assembly and immediately contact the Yoeleo Customer Service or your nearest Yoeleo dealer.
  • All edges of the handlebar, stem, top cap, and spac-ers in contact with the steerer tube should be rounded out to eliminate stress points.
  • Do not drill, remove parts, or modify the frame components without instruction or acknowledgment from Yoeleo HQ team. Not following this warning could result in injury or death.
  • Do not install incompatible components. Use of other components may compromise the integrity of the assembly.

Tools and Torque Specification

Use the proper tightening torques; it is essential for the correct function and to avoid loosening or structur-al damages. In certain cases, tightening torques ensure mechanical couplings, in other cases they prevent loosening. Depending on the application, the threads should be greased or treated with thread-lockers. Refer to the chart below for the proper torque to be applied and for the treatment. Suggested thread-lockers are:Loctite 222 or low strength threadlocker equivalent. To lubricate threads never use lithium-based greases.

Use CARBON grip paste (NOT CERAMIC GREASE) on the seat post before installing it. After first ride, and consis-tently thereafter, recheck the tightness of each bolt to ensure secure attachment of the components.

Housing and Hose Length Recommendation To properly assemble the Yoeleo G21 Disk we recommend using the following housing and hose lengths, which will then be cut according to the frame and handlebar size.

Mechanical Groupset

Installation and Hose Routing

Route the rear brake hose from the left chainstay hole to the top tube. RB hose must route above the Bottom Bracket (BB) sleeve. Refer to chapter

“4. HOUSING AND HOSE LENGTH RECCOMENDA-TION” for the correct hose length

5.2 Install the rear brake caliper. Connect the rear brake to the left chainstay. Tighten the bolt until the brake is locked. It will be fully tightened only after alignment with disc rotor (refer to chapter “6. FINAL CHECKS” for more details).

ATTENTION! follow the brake OEM assembly instruc-tions

Route the front brake hose through the fork entry hole (left fork arm) and up to the exit hole on the steer-er tube. Refer to chapter

“4. HOUSING AND HOSE LENGTH RECCOMANDA-TION” for the correct hose length.

Install the front brake caliper to the fork. Tighten the bolt until the brake is locked. It will be fully tight-ened only after alignment with disc rotor (refer to chapter “6. FINAL CHECKS” for more details). ATTENTION! follow the brake manufacturer assem-bly instructions

Steerer Tube Assembly Preparation: Install the crown race and lower headset bearing (Black Bearing (7mm)) into the proper frame seat. ATTENTION! apply grease around the bearing frame seat.

Mechanical Groupset Installation

Rear Derailleur Installation: Install the rear derailleur to its hanger. Tighten follow-ing OEM torque spec.

Front Derailleur Installation: Install the front derailleur to its hanger. Tighten the bolt until the derailleur is in place. It will be fully tightened, following OEM specs, only at the final tuning stage (refer to chapter “6. FINAL CHECKS” for more details).

Route rear derailleur cable housing with the recommended length mentioned in chapter  From Right Chanstay Hole All The Way to The Headtube

Route front derailleur cable housing with the recommended length mentioned in chapter 4.2 From Front Derailleur Cable Hole Upper Bottom Bracket All The Way to The Headtube.

Install BB386 presfit, and make sure all 3 cables are routed on top of BB sleeve cylinder.

Install foam house from the headtube opening and slide it through until it sit in the middle of downtu-be  Push the steerer tube up into the head tube. Grab the front brake hose inside the bearing and push up through the head tube.

Use a proper support for the fork while installing to avoid fork dropped during assembly. By now all four cables must appear on the head tube.

Install the upper bearing (Black bearing) in its frame sit. Make sure to grab the rear brake hose and the front brake hose between bearing and steerer tube.

ATTENTION! apply grease around the bearing frame seat

Install The Compression Ring Attention: the cut on compression ring/ C ring must be facing forward. Install the head set top cap. Make sure to keep all cable nice and tidy in front of the frame.

Handlebar installation guideline Install the shift levers on the H9v2 handlebar following the OEM specs

Handlebar cable routing:

• Route the rear derailleur housing from the front exit hole on the stem through the handlebar and out at the right exit hole at the lever.
• Route the front derailleur housing from the right exit hole on the stem through the handlebar and out at the left exit hole at the lever
• Route front brake hose from the front exit hole on the stem through the handlebar and out at the left exit hole at the lever
• Route rear brake hose from the front exit hole on the stem through the handlebar and out at the right exit hole at the lever

Headset Adjusting  Handlebar stack can be adjusted using the split spacers by 10mm, 3mm and/or by 5mm.

Interlock, as illustrated above, the required number of spacers between top cap and the handle-bar. Be careful that spacers and top cap have pins for alignment. Make sure that all cables are well positioned into the proper notch, and they are not twisted around each other

Install the number of spacers previously planned between handlebar and top cap. Slide the handlebar down the steerer tube, until the spacer is firmly seated on the top cap. Slightly tighten the handlebar to keep all headset component in place.

Mark a line on the steerer tube inline with the top edge of the stem.

Remember to ensure your final stem position before final steerer tube cut, if you hesitate, please add some round spacer on top of the stem, then follow the similar instruction.

Disassemble the handlebar from the steerer tube, then we can cut the steerer tube.

ATTENTION! the actual cutting line must be 5 mm below the line made in the previous

Slide the handlebar down along the steerer tube till the top of the last spacer. Make sure to slightly push all housings back into the frame to avoid kinks. Firmly tighten the head set as usual, placing the expander and the top cover. For the correct tightening torques refer to the chapter

TOOLS AND TORQUE SPECIFICATION

The aspect of the rightly assembled headset should be like that showed below.

Final Check Final tightening of the brakes checking their correct centering, follow the OEM instructions.

ATTENTION! Disc brake calipers are provided loosen, make sure to tighten them following OEM specs before first ride.

ATTENTION! Make also sure that the disc brakes are properly bled (following OEM specs) before first ride.

Fine tune the drivetrain (both rear and front derail-leur) following OEM specs.

Before first ride carefully check the correct assem-bly and operation of all components, repeat these controls periodically.
