Handlebars
Installation
- Ensure the stem clamp bore is clean, smooth, and free of sharp edges or burrs where it contacts the handlebar
- Apply a thin layer of appropriate assembly compound to the handlebar clamping area before fitting. For titanium handlebars, use an anti-seize compound (e.g., copper or titanium-specific anti-seize). Do not use carbon assembly paste on titanium
- Centre the handlebar in the stem clamp. The centre marking on the handlebar must be aligned within the stem clamp area
- Tighten stem clamp bolts evenly and incrementally in a cross pattern. Do not fully tighten one bolt before moving to the next
- Ensure even clamping gap — the gap between the stem faceplate and stem body should be approximately equal on both sides
- Do not use handlebar extensions, bar ends, or accessories that apply leverage beyond the designed clamping points
Width Reduction
- Width reduction must be carried out by a qualified mechanic
- Cut evenly from each side to maintain handlebar symmetry
- Remove all sharp edges and burrs from the cut ends
- Do not reduce width beyond the minimum width indicated in product-specific documentation
- Re-install bar-end plugs after cutting. Riding without bar-end plugs is a safety hazard
Torque Specifications
| Fastener | Torque |
|---|---|
| Stem clamp bolts (titanium handlebar) | 4–5 Nm |
| Brake lever / shifter clamp bolts | 3–4 Nm |
| Grip lock bolts | 1–2 Nm |
Stems
Installation
- Clean the steerer tube and stem bore before installation
- Apply appropriate anti-seize compound to the steerer tube clamping area for titanium stems. Copper or Ti prep paste is recommended for titamium to titanium surfaces
- Apply appropriate anti-seize compound to the stem faceplate and steerer bolt threads. Copper or Ti prep paste is recommended
- For carbon steerer tubes, use carbon-specific assembly paste on the steerer interface to prevent slippage and reduce the required clamping force
- Ensure the stem is positioned at the correct height on the steerer tube. The steerer tube must extend sufficiently into the stem bore — refer to the minimum insertion marking on the steerer tube
- Tighten steerer clamp bolts evenly and incrementally. Do not fully tighten one bolt fully before the other
- Confirm the stem is aligned with the front wheel before final tightening
- Check headset preload adjustment before tightening steerer clamp bolts — the stem clamp should be tightened after headset bearing preload is correctly set
- Our stems have are designed to have the faceplate tightened flush at the top with a small gap at the bottom. Make sure to tighten the top bolts first (hand tighten only), then tighten the bottom bolts. After all bolts are hand tight, proceed to tighten the top bolts to torque spec followed by the bottom bolts.
Torque Specifications
| Fastener | Torque |
|---|---|
| Steerer clamp bolts) | 5-6 Nm |
| Faceplate bolts (handlebar clamp) | 4–5 Nm |
| Top cap bolt (preload only) | 1–2 Nm |
Rims
Installation and Setup
- Wheel building and truing should be performed by a qualified wheel builder or mechanic
- Use the correct spoke count, spoke type, and lacing pattern as specified for the rim
- Ensure uniform spoke tension across the wheel. Uneven tension can lead to premature spoke or rim failure
- Install rim tape that fully covers all spoke holes before fitting a tubeless tyre setup. Ensure the tape is rated for tubeless use and is seated without wrinkles or gaps
- Use only tubeless-compatible tyres and sealant. Follow tyre manufacturer guidelines for inflation pressure
- Do not exceed the maximum tyre pressure specified for the rim
Inspection and Maintenance
- Inspect rims regularly for cracks, dents, flat spots, or sidewall wear — particularly after impacts with rocks, roots, or other obstacles
- Check spoke tension periodically and re-tension as needed
- A rim that has sustained a significant impact should be inspected by a qualified mechanic before further use, even if no damage is visible
- Replace the rim immediately if any cracks, deformation, or structural damage is detected
Tyre Pressure
| Parameter | Specification |
|---|---|
| Maxiumum Tyre Pressure | 45 PSI |
Hubs
Installation
- Confirm hub axle compatibility with the frame or fork (axle standard, spacing, and thread pitch) before installation
- Install the wheel with the correct orientation — check disc rotor side alignment
- Tighten the thru-axle or quick-release to the frame or fork manufacturer’s specified torque
- Ensure the disc rotor is correctly mounted to the hub using the appropriate interface (6-bolt or Centre Lock) and torqued to specification
 Maintenance
- Hub bearings should be inspected periodically for play, roughness, or contamination
- Freehub engagement mechanism should be serviced every 6 months, or every 3 months in wet or muddy conditions
- Do not use a high-pressure washer directed at hub bearings or seals
- Apply appropriate lubricant to the freehub body and engagement mechanism during service
Torque Specifications
| Fastener | Torque |
|---|---|
| 6-bolt disc rotor bolts | 6–8 Nm |
| Centre Lock lockring | 40 Nm |
| Thru-axle (refer to frame/fork manufacturer) | 8–15 Nm |
| Cassette lockring | 40 Nm |
Pedals
Installation
- Pedals are side-specific — the right (drive-side) pedal has a standard right-hand thread; the left (non-drive-side) pedal has a left-hand (reverse) thread
- Apply anti-seize compound to the pedal thread before installation to prevent seizing, particularly with titanium crank arms
- Thread pedals in by hand first to avoid cross-threading. If resistance is felt, stop and check alignment before continuing
- Tighten pedals securely using a pedal wrench or hex key to the specified torque
- Check pedal tightness periodically — pedals can loosen during use, particularly in the first rides after installation
 Maintenance
- Inspect pedal bodies, spindles, and platform pins regularly for wear or damage
- Replace bent or worn platform pins promptly — missing or worn pins reduce grip and increase the risk of foot slippage
- Service pedal bearings at 6-12 months, or every 3-6 months in wet and muddy conditions
Torque Specifications
| Fastener | Torque |
|---|---|
| Pedal to crank arm | 30–35 Nm |
| Platform pins | 1-1.5 Nm |
Frames
Pre-Build Inspection
- Inspect the frame thoroughly before building — check all welds, surfaces, and interfaces for any marks, cracks, dents, or irregularities
- Confirm that the headtube, bottom bracket shell, and all pivot/axle interfaces are clean, properly faced, and chased (threaded interfaces) before fitting components
- Verify frame sizing and compatibility with all intended components (headset standard, bottom bracket standard, axle spacing, seatpost diameter, etc.) before commencing the build
 Assembly
- Frame assembly should be performed by a qualified mechanic
- Apply anti-seize compound to all threaded interfaces (bottom bracket, headset cups, thru-axle threads, brake mount bolts, derailleur hanger bolt) to prevent galvanic corrosion and seizing — particularly important with titanium
- Apply anti-seize or an appropriate friction compound to the seatpost before insertion. For titanium seatpost in titanium frame, use titanium-specific anti-seize
- Observe the minimum seatpost insertion from the seatpost manufacturer. The seatpost must be inserted to at least this depth at all times
- Ensure the derailleur hanger is correctly installed and aligned before fitting the rear derailleur
- Route all cables and hoses in accordance with the frame’s intended routing path. Avoid kinks, sharp bends, or contact with moving parts
Ongoing Inspection
- Inspect the frame regularly for cracks, dents, paint lifting near welds, or any deformation — particularly after crashes or heavy impacts
- Check all bolted interfaces periodically for correct torque — bolts can loosen through vibration and use
- For full-suspension frames, inspect pivot bearings, hardware, and linkage for play, wear, or contamination at regular intervals
- A frame that has been involved in a crash or significant impact must be thoroughly inspected before further use. If in doubt, contact Roost Bike
- Do not continue to ride a frame that shows any signs of cracking, deformation, or structural damage. Replace immediately.
Torque Specifications
| Fastener | Torque |
|---|---|
| Seatpost clamp bolt | 4-6 Nm |
| Bottle cage bolts | 3-5 Nm |
| Rear thru-axle | 8-12 Nm |
| Brake caliper mount bolts | 6-8 Nm |
| Derailleur hanger bolt | 8–10 Nm |
| Pivot hardware (full suspension) | Refer to frame-specific documentation |
