Overview

This document is a service manual supplement for the 2022 Trek Roscoe 7, 8, and 9 bicycle models, providing essential information for assembly, maintenance, and safe operation. It covers various components and procedures, emphasizing proper torque application, threadlocker use, and specific installation guidelines to ensure the bicycle's integrity and rider safety.

The manual begins with a table of contents, outlining key sections such as Safety, Dérailleur Hanger, Cabling, Frame Guards, Specifications, and Suspension. Each section provides detailed instructions and visual aids to guide users through the necessary steps.

Safety

The safety section highlights critical warnings regarding hardware tightening and threadlocker application. It stresses the importance of tightening all hardware to the specified torque to prevent deformation, breakage, or loosening of components, which could lead to damage to the bicycle and potential injury to the rider. Over-tightening can deform or break parts, while under-tightening can cause them to become loose.

Another crucial safety warning concerns the re-application of threadlocker. For all reused fasteners that originally had pre-applied threadlocker, it is essential to clean them with isopropyl alcohol and apply new threadlocker before re-assembly. Failure to do so can result in fasteners loosening, potentially damaging the bicycle and causing injury.

A legend is provided to clarify symbols used throughout the manual, indicating where to apply grease, where not to apply grease, where to apply threadlocker, specified torque values (Nm), and zip tie locations.

Dérailleur Hanger

This section details the installation and maintenance of the derailleur hanger. It includes an exploded view of the assembly, showing the thru axle, derailleur hanger, washer, and bolt, along with their respective part numbers. The thru axle requires a torque of 10 Nm, while the bolt securing the derailleur hanger needs 25 Nm.

Specific tools required for this procedure include an 8 mm hex tool and a torque wrench with an 8 mm hex bit for left-hand thread.

Important notices for the derailleur hanger include:

  • No grease application: Grease should not be applied to the derailleur hanger or bolt; only the thru axle should be greased.
  • UDH compatibility: The bicycle frame is designed for a Universal Derailleur Hanger (UDH). The thru axle must be compatible with a UDH, specifically M12x1.0 with a 12.7 mm thread.
  • Frame-specific washer: The washer is frame-specific, and only the compatible washer should be installed.
  • Torque warning: Over-tightening the bolt can cause the hanger to break. Users are advised to refer to the SRAM user manual for additional information on UDH at www.sram.com.

Cabling

The cabling section illustrates the internal routing of cables for the derailleur, rear brake hose, and dropper post. It provides a visual guide with numbered components:

  1. Derailleur cable
  2. Rear brake hose
  3. Dropper post cable
  4. Zip tie guide for internal routing (W513977)
  5. Plug cable guide (W5253075) Stars indicate zip tie locations.

Tips for zip tie guide installation are included:

  • Crease creation: Before inserting a zip tie, bending it in half to create a crease makes it easier to wrap around cables and pull through holes.
  • Tool use: A hook tool and a pick tool can be used to hold cables and guide zip ties around them effectively.

Frame Guards

This section covers the installation of frame guards, specifically the chainstay guard and downtube guard.

  1. Chainstay guard (W5252847)
  2. Downtube guard (W5253074) Stars indicate zip tie locations for securing the guards.

For the downtube guard, specific cleaning instructions are provided:

  • Surface preparation: Use isopropyl alcohol to clean the frame surface where the guard attaches. Allow the alcohol to dry completely before applying the guard.
  • Paint warning: A notice warns against cleaning the entire frame with isopropyl alcohol, as it could damage the paint.

Specifications

The specifications section provides detailed measurements and compatibility information for various components, including chainline, chainring, rear brake mount, maximum tire size, seat post, and bottom bracket/ISCG tabs.

Chainline (1x only)

This subsection illustrates the chainline measurement and provides a table for chainring compatibility:

  • Chainline: 52 mm or 55 mm
  • Chainring options: 28T, 32T, 34T

Rear Brake Mount

This part specifies the minimum and maximum rotor sizes for the rear brake mount:

  • Minimum: 160 mm, direct mount
  • Maximum: Adaptable to 180 mm

Maximum Tyre Size

A notice emphasizes that actual tire measurements may vary, and users should verify sufficient clearance between the tire and frame. Trek recommends a minimum of 6 mm clearance above and on the sides of the tire to prevent damage to the bicycle.

  • Wheel set: 29" or 27.5"
  • Maximum tyre size: 29.0" x 2.60" or 27.5" x 2.60"

Seat Post

A critical warning is issued regarding the seat post:

  • Minimum insertion: Always follow the seat post manufacturer's minimum insertion recommendation. Failure to do so could damage the seat post and result in rider injury.

A table provides seat post measurements:

  • Maximum insertion:
    • Extra small: 190 mm
    • Small: 200 mm
    • Medium: 240 mm
    • Medium/large: 250 mm
    • Large: 250 mm
    • Extra large: 250 mm
  • Minimum insertion: 75 mm* (asterisk indicates "Follow the seatpost manufacturer guidelines.")
  • Seat tube inside diameter: 31.6 mm
  • Seat tube post clamp outer diameter: 36.2 mm

Bottom Bracket/ISCG Tabs

This section lists the compatible bottom bracket and ISCG tabs:

  • Bottom Bracket: BSA73
  • ISCG Tabs: ISCG 05

Suspension

The suspension section outlines the initial steps for setting up the bicycle's suspension.

  • Sag determination: The first step is to determine the sag. All other suspension settings should be adjusted after this initial step.
  • Resources: Users are directed to the suspension setup card included with their bike or the online suspension calculator at Trekbikes.com/suspension-calculator for further guidance.

Fork

A warning for the fork emphasizes:

  • Maximum fork length: Exceeding the recommended maximum fork length could damage the bicycle and result in rider injury.

A table provides fork dimensions:

  • Maximum travel:
    • XS: 120 mm
    • SM-XL: 150 mm
  • Maximum length:
    • XS: 533 mm
    • SM-XL: 563 mm

Overall, this service manual supplement is a comprehensive guide for the 2022 Trek Roscoe 7, 8, and 9 models, focusing on safe and correct assembly, maintenance, and component compatibility. It uses clear instructions, visual aids, and explicit warnings to ensure that users can properly set up and maintain their bicycles, thereby enhancing both performance and safety.
