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.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.
