Title: Front forks and Bearings
Post by: Franklueck on May 09, 2025, 06:35:29 PM
Hi Guys,
Does anyone have any information or replacement Front forks and Head Bearings?
I own a Radcity 5 Plus with 5300 Miles, Its been a great bike but my forks and bearings are just plain worn out I think, as well as at least one good crash

Any suggestions Please

To maintain your bike's intended geometry, select a 27,5" or 28" suspension fork offering 63-65 mm of suspension travel that can handle the width of your tire. A 300 mm steerer tube length is crucial to directly fit your frame and headset without needing extra parts, which could also affect your riding position and the bike's fit.

The fork must be compatible with a 1 1/8" headset, have a disc brake mount (confirm the specific mount type), and use a 9 x 100 mm quick release skewer for wheel attachment. For the headset, a 1 1/8" Zero Stack (ZS) headset with a 44mm upper cup inner diameter for a 28.6mm steerer and a 44mm lower cup inner diameter for a 30mm crown race (ZS44/28.6 - ZS44/30) should work, though confirming this before purchasing is highly recommended to ensure correct fit within the head tube.

Given the specialized tools and technical knowledge required for safe and proper fork installation, which is critical for preserving the bike's geometry and your safety, I would recommend to buy a suitable Suntour fork from a local bike shop and have their experienced mechanics handle the fitting. This ensures the job is done correctly, safeguarding your bike's performance and saving you the investment in tools and the time needed to install the fork.
