Common problem nr.5 - Central Bearings (Középcsapágyak)
One of our members had this problem with his 40-50 year old fem Waffen Fahrrad.
The solution to both save the bicycle as an everyday instrument of transport, but
to not to go for a 2 year hunt trying to find original parts (since he has to relocate often
due to his job anyway) made him go for option MONOBLOCK!
