It is even 20 grams lighter than used shimano SM-RT51

Weight: Joytech D041-15 and ZZYZX Front Hubs

Joytech D041-15 is a cheap and heavy ball bearing front hub from a stock wheelset of my Norco Sight A 7.2 2014. More crappy front hub I can't even imagine. Its weight is 290 grams and it has loose balls inside.

Stock ZZYZX front hub from my Corratec X-Force 0.3 2012 is much better. It has 2 sealed bearings and construction similar to Hope Pro 2 hubs. This ZZYZX hub is for 20mm axle, but I have transformed it to 15mm using Hope Pro 2  adapters. The weight of this hub with these adapters is 220grams.
