In addition to making puns, we're also very good at helping with Hope technical issues and compatibility questions.


The Pro2, Pro2 EVO and Pro 4 front hubs all use a pair of 20x32x7mm bearings.  We like using the SKF bearings as replacements as we've found them to be super high quality, really durable, and cost-effective.

The bearing codes are 6804 or 61804 if you choose to buy other bearings.
