Handlebars & Shifters Maintenance

Your handlebars, stem, and shifters are not just control points, they directly influence comfort, responsiveness, and safety. Worn bar tape, loose bolts, or sluggish shifters can affect your handling and enjoyment on every ride.

In this final chapter, we’ll cover the essential checks and maintenance tasks to keep your cockpit tight, clean, and running smoothly.

a. Why Handlebar & Shifter Maintenance Matters

• Control:
  • Your bars and shifters are your direct interface with the bike.
• Comfort:
  • Fresh tape and smooth levers improve long-ride enjoyment.
• Safety:
  • Loose stems or cracked bars can cause serious crashes.

Pro Tip: Do a quick handlebar and shifter check every few rides and a full inspection monthly, especially after a fall or intense training.

b. What to Look Out For

• No play in headset when braking and rocking the bike
• Shifters return cleanly and feel crisp
• No cracking or corrosion around bar/stem junctions
• No movement or creaking from bars or shifters
• Bar tape is clean, intact, and comfortable

1. Handlebar & Stem Safety Check

Your handlebars and stem connect you directly to the bike's handling. Regular checks help you avoid dangerous failures and ensure responsive control.

a. What You’ll Need

• 4mm, 5mm or 6mm hex keys (depending on bolt type)
• Torque wrench (recommended)
• Clean rag
• Light source for visual inspection

b. Handlebar & Stem Check: Step-by-Step

1. Check for headset play:
   1. Hold the front brake and gently rock the bike back and forth.
   2. Feel for knocking or clicking at the headset.
   3. If present, adjust the headset preload (via top cap) and retighten stem bolts.
2. Check stem & bar bolts:
   1. Use a torque wrench to check stem faceplate and steerer clamp bolts.
   2. Tighten to manufacturer torque spec (usually 4–6 Nm).
   3. Uneven torque on faceplate can stress or damage carbon bars.
3. Inspect for damage:
   1. Remove bar tape if needed to inspect full bar surface.
   2. Look for cracks, dents, or corrosion at clamp zones and bends.
   3. After a crash or impact, always check stem and handlebar for hidden cracks.

Note: Replace any damaged or questionable bars, especially if carbon.

2. Shifter Function & Care

Shifters are generally low-maintenance, but regular inspection and cleaning ensures reliable gear changes, especially after wet rides, heavy use, intense sweat on indoor set-ups or long-term storage. Deep cleans should not be required after every ride and only done if issue is present.

a. What You’ll Need

• Torque wrench (if lever bolts need adjusting)
• Dry microfibre cloth or dry soft toothbrush
• Compressed air (optional)
• For deep-clean:
  • Isopropyl alcohol spray
  • Silicone-based spray dry-lube
• For loose pivot bolts:
  • Hex keys

b. Shifter Check: Step-by-Step

1. Test shifter feel:
   1. Shift through all gears while pedalling on a stand.
   2. Ensure levers return quickly and feel crisp.
   3. If sluggish or sticky, clean the mechanism.
2. Inspect cables and housing:
   1. Check for frayed cables under the hoods.
   2. Look for kinks or cracks in outer housing.
   3. Slow shifting may indicate cable corrosion or friction — consider replacing cables.

c. Shifter Deep Clean: Step-by-Step

1. Wipe down shifter and test functionality is crisp.
2. Check for moisture/dirt buildup under the hood and around levers:
   
   1. Remove with cloth/brush or compressed air.
3. For deep-cleaning mechanical shifters:
   1. Use a generous spray of isopropyl alcohol (not degreaser) to flush out grime.
   2. Add very small amount of silicon spray dry-lubricant (not wet-lubricant) to pivot points.
4. For deep-cleaning electronic shifters:
   1. Spray with compressed air.
   2. Wipe with cloth dampened with isopropyl alcohol or electronic contact cleaner around shifter and then pivot hinges.
   3. Check and clean connections as needed, reseating afterwards.
   4. Dry well with compressed air or dry clean cloth.
   5. Add very small amount of silicon dry-lubricant spray (not wet-lubricant) to pivot points only, careful to avoid buttons, charge-points & wiring.
5. Check lever pivot bolts and tighten if loose
   1. Rarely loose and usually only after a crash.

3. Bar Tape Refresh

Bar tape provides grip, comfort, and aesthetics. Worn or dirty tape can reduce control and enjoyment — replacing it is an easy and rewarding upgrade.

a. What You’ll Need

• New bar tape
• Scissors and finishing tape
• Bar-end plugs
• Clean rag and degreaser (optional)

b. Bar tape replacement: Step-by-Step

1. Inspect tape condition:
   1. Replace tape if it’s torn, worn thin, coming loose, or permanently dirty.
2. Remove old tape:
   1. Unwrap tape, remove any sticky residue with isopropyl alcohol.
3. Re-Wrap bars:
   1. Start at the bar ends and wrap upward toward the stem.
   2. Overlap evenly with moderate tension.
   3. Tuck in ends and insert bar-end plugs securely.
4. Choose the right tape:
   1. Consider extra padded or grippy textures for endurance, comfort, or wet-weather riding.
   2. Cork, gel, and tacky synthetic tapes are popular options.

Pro Tip: Overlap evenly and maintain steady tension for a neat finish. Avoid overstretching cork tape.

4. Top Tips Round-Up

• Always use a torque wrench on stem and bar bolts, over-tightening can crush carbon or strip aluminium.
• Clean shifters with alcohol only, avoid greasy lubricants.
• Inspect bar tape regularly for wear and grime.
• Bar movement or creaking under load could mean bolts are loose or parts are cracked.
• After a crash, always inspect handlebars, levers, and stem thoroughly.
