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.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.

Good enough for Trump, good enough for me.
Size: 9, Color: Black Crazy Horse
Not gonna lie, the only reason I first bought these were because Trump likes this brand of shoes and the fake media ran a story about it. Once I got them and tried them on I was shocked just how comfortable they were. These are very nice and comfortable. I will definitely be buying more from this brand. Nice job Florsheim. 45/47

Excellent shoes - good fit, nice look.
Excellent shoes - great value for money! Attractive and well built. Got several unsolicited compliments from co-workers. They are stiff at first and require a bit more of a break-in period than some other shoes I have purchased lately. I hope that is a sign of durability ...
