I bought a DRT 1.3 about 2 years ago. It came with the Suntour Raidon RL 120mm fork. Sometimes after hitting a few bumps, the fork will lose all pressure. It doesn't lose pressure after sitting in the garage or sometimes it will last a whole mellow ride. Is there a service protocol or part replacement that might solve the problem?
Thanks for the question! It sounds like its time to have your seals replaced. I'm particularly curious about what you mentioned re: it doesn't lose pressure when sitting, only sometimes when used. This indicates that there might be more going on inside the fork than just a regular worn out seal. Have you had the fork serviced any time since you bought it?
Suspension service and overhaul is typically performed by professional mechanics in a shop, as it takes specialized tools and parts.
In any case, the best course is to take this to a professional mechanic. REI bike shops are not currently offering technical service, but when your local Co-op reopens, the mechanics there will be able to take a look and see exactly what's causing the issue and get you back out riding as soon as possible!
I hope this is helpful- feel free to reach out if you have additional questions!
