I have a RockShox Reverb seatpost on my mountain bike and it is a great piece of technology for remotely adjusting the height of the saddle.
However, some people have expressed concern, as the seatpost is exposed to the elements, that there may be some risk of contamination of the inner mechanism of the Reverb. I think that the seals on the Reverb are good enough to keep the unit contamination-free but there is always that nagging doubt in the back of the mind.
When rides are going to be muddy, people normally attach a full rear mudguard to protect themselves and this would also keep the Reverb clear of mud. But there are some days where a ride just does not warrant a full rear mudguard, such as on hot sunny days, but there may still be a chance of coming across mud.
I decided to get one of those thin mini-mudguards such as the Ass Savers “SmartAss” or Mucky Nutz “Butt Fender” that attach to the saddle rails, with the intent to see if I could modify it to act as a permanent mudguard for the Reverb. So I bought a “SmartAss” http://ass-savers.com/ and re-shaped it with scissors such that I could still attached it to the saddle rails but also bend it through nearly 80 degrees to cover the Reverb. I also use a street-legal rear reflector (with red LED) that mounts on the saddle rails and this was essential to keep the SmartAss bent at that approximately 80 degree angle. I’m sure that there are other solutions to keeping that SmartAss held at that angle. The angle is such that it does not get in the way of attaching a full rear mudguard. The SmartAss is also just clear of the rear tyre when the Reverb is fully down and is still usable with a full rear mudguard and the Reverb all the way down; I still need to test this more fully on the trails.
Today was a nice spring day (finally!) and I wasn’t about to attach a rear mudguard. So I went riding and soon came across a number of muddy holes. No problem. See photo below straight after the ride (note that the white skull is a reflective sticker that I attached on the SmartAss).
As you can see, the modified SmartAss has done a very decent job of keeping the Reverb mud-free. I’m still not convinced at all that the Reverb needs this additional level of protection but the modification is cheap and gives that peace of mind. Result!
I hope to post a long-term review later this year.
