Fork seals, a simple part on your bike, holds fluid in your fork to assist in suspension and dampening when you hit a bump. That Fluid is 'just there' when was the last time you even thought about it or changed it?
The usual time you are reminded about it is when your fork seal fails.
The normal scenario is you are riding along and there has been no warning of the failure, you then need to stop and grab the front brake and you don't slow down as normal. Quickly you hit the back brake and stop, jump off your bike to see whats going on.
Chances are you have an oil stain on your boot or pant leg and oil all over the front brake caliper?
This is one of those situations where it possibly could make your bike unrideable, and cost you a few hundred dollars or more to have fixed if you don't have the skill set yourself.
Enter fork seal cleaners - the culprit that is making the fork leak fluid is most likely just a small spec of dirt or sand that is allowing the fluid to escape. As the fluid is a very thing viscosity usually in the 2.5 to 7.5 weight range
Two companies have you covered, one fits in your wallet, the other on the fork leg.
I have both, I have found the Motion Pro Seal mate to be useful but can fail after a few ueses, it becomes brittle, but at $7.50 is not too hard on the wallet
The other is from Risk Racing and called the Seal Doctor
I'll explain more and other options in the next post to get you back on the road and correct the leak
