Product Overview

Upgrade your 7-speed drivetrain with the Shimano TOURNEY MF-TZ510 7-Speed Freewheel 14–28. This freewheel features seven durable black steel cogs arranged in a 14-16-18-20-22-25-28 tooth configuration.

Its thread-on design installs onto any standard 7-speed hub without a spoke protector.

  • Smooth Shifting: Precision machining ensures consistent, reliable shifts under load.
  • 7-Speed Compatibility: Works with Shimano Tourney/Tourney TZ rear derailleurs and HG/IG 6/7/8-speed chains.

  • Compact Weight: Approximately 375 g, balancing strength with manageable weight for everyday riding.

Usage Recommendations

Entry-Level Mountain Bikes

Ideal for hardtails or basic full-suspension bikes on Wicklow’s gravel trails. The 14–28 T range helps you conquer loose climbs and maintain momentum on rolling terrain.

Hybrid & Commuter Bikes

Perfect for daily commutes in Dublin. Use lower gears to tackle Cemetery Road or Daingean Road hills, and shift up for fast rides along the Royal Canal Cycle Route. The black steel finish stands up to frequent rain and road debris.

Recreational & Leisure Rides

Great for weekend spins around Phoenix Park or casual tours along coastal routes. Pair with a Shimano Tourney TZ derailleur and CN-HG40 chain for smooth, quiet shifting over mixed surfaces.

Replacement & Upgrade

Swap a worn freewheel or upgrade from a narrow-range model. The MF-TZ510’s wider spread reduces cross-chaining and improves cadence options. Apply a light grease to freewheel threads before installing to prevent seizing.

Recommended Accessories & Complementary Items

  • Shimano CN-HG40 7-Speed Chain: Ensures crisp shifts and extended drivetrain life.
  • Shimano Tourney TZ Rear Derailleur (RD-TZ50 or RD-TZ500): Provides reliable indexing for 7-speed setups.
  • Freewheel Removal Tool: Park Tool FR-5 and chain whip to remove and install the freewheel safely.
  • Chain Whip Tool: Holds the freewheel stationary while using the removal tool.
  • Rear Wheel Service Kit: Includes grease and cone wrenches for bearing maintenance before installing the new freewheel.
  • Drivetrain Cleaning Kit: Brushes and degreaser to keep cogs, chain, and pulleys clean—improves shifting performance.

Tips & Tricks

  • Grease Threads: Lightly grease hub threads before installing to prevent seizing and ease future removal.
  • Tighten Correctly: Hand-tight plus a quarter-turn with a freewheel tool is usually sufficient—avoid over-torquing to protect hub threads.
  • Chain Compatibility Check: Use an HG-compatible 7-speed chain like CN-HG40. A properly sized chain ensures smooth engagement across all cogs.
  • Inspect Cog Wear: Look for “shark-tooth” profiles on each cog—replace the freewheel and chain together if teeth appear hooked to prevent skipping.
  • Adjust B-Screw: When installing a wider freewheel, set the derailleur B-screw so the upper pulley clears the largest cog by 5–6 mm.
  • Test Ride & Re-Check: After installation, ride through all gears, then re-check freewheel tightness and derailleur indexing for optimal performance.

Great dressy sneaker to wear with business casual or jeans
Size: 11, Color: British Tan/Ivry
I got these for my husband to wear with jeans or business casual dress pants. They look sharp and professional and dress up jeans if you're going out. He says they fit comfortably and he can walk on them all day without his feet hurting. They are beautiful genuine leather so they don't get stinky. I got my husband's normal size and they fit to size.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

Very nice, but sizing is inconsistent
Size: 10 Wide, Color: Ivory/White/British Tan
All of these Cole Haan shoes are extremely well made and I like the styling. On the other hand, the sizing is very inconsistent and you may end up having to do a lot of returns trying to find the right size. Then if you get a different color of it, you may find the sizing different yet again. If you find your right zie, they are really nice shoes at a very reasonable price for the quality.
