Can I run 27.5 plus rims and tires on this frame?

Yes, up to 27.5 x 3.25” tires can be fitted. Using rim/tires smaller than this diameter will change the bottom bracket height and might affect pedal clearance.

Can I run 5” tires on this bike?

While the Bloodhound Trail is designed around 27.5 x 3.8 wheel/tire platform, here are some other sizes that will also work. Please note that alternate wheel and tire choices may effect your BB height.

27.5 x 3.8–4” on a 80mm rim or 26 x 4.5” on a 80mm rim.

29 x 2.3–3.0” (includes 29 plus)

What is the warranty for this bike?

I crashed and dented (or cracked) my frame. Is it safe to ride?

Stop riding your frame immediately and take it to the nearest Heller Bikes dealer for inspection. Any dent or crack in the frame tube suggests a structural weakening of the frame and should be considered a safety risk.

Can I use a suspension fork on this frame?

Yes, this frame was designed and tested for use with a suspension fork with an axle-to-crown length up to 511mm (typically 100mm of travel). Check the fork manufacturer’s specifications to ensure the model and travel combination you intend to use is equal to or less than this length. Using a longer length fork could result in frame failure and will void the frame warranty. Forks with a 45mm offset are acceptable (increases mechanical trail by 6mm) but 51mm offset are strongly recommended.
