I use my strida everyday. Since few months my freewheel does a lot of noise when I stop pedaling. I think I need to add some lubricant or grease inside.
I have unmounted the freewheel, unscrewed the two parts, I can see the balls on each side. I want to open the freewheel to clean inside and add some lubrifient or grease.
What is the method and/or tools to open it ? I have tried to inject some lubricant without opening it but the noise is still there…
Unless you are very careful, I would recommend to NOT take the freewheel apart.
There are 2 ball tracks on the freewheel: one on each side, so it might become a nightmare to reassemble it.
Either replace it (which I did), or clean it by putting it in a petrol solution to dissolve the grease and hope that dirt particles will come out, then put some thick oil or hot grease inside it through the gap between the moving and the non moving part.
As mentioned by BSA, re-assembling the freewheel with less balls is of course not good, otherwise the manufacturer would have done it to reduce the cost…
These are the negative effects:
Accelerated wear with,on the long term, more lateral/angular play in the freewheel which in the worst case could make the belt climb on the flanges of the rear pulley and damage it.
If you are a sporty cyclist and push hard on the pedals, then the bearings will deteriorate more quickly.
Less smooth running when not pedalling with potentially more drag and more noise.
After doing some research, I thought 3.175mm is the common size used in the bike. However, I just couldn’t fix them into the aluminium freewheel. Even with just 46pcs per side instead of 47pcs, it just couldn’t turn smoothly. Hence I will replace them with 3mm ball bearings.
