Durable and smooth
The hellbender 70s are in between the 40 and 110 series and I prefer these as they are reliable, smooth and decently priced. The integrated headsets are fool proof as you just have to grease and plop them in. Just make sure you know the measurements for the top and bottom. I installed these on my ibis dv9 and have had no issues as my steering is precise and smooth.
