What’s wrong with my Reverb?

I recently got a broken reverb from my friend.
He said that it had had some sag and finally it totally collapsed.
I of course was interested if it could be fixed.

The post could be compressed by hand and did not hold the position.

First I noticed that it was lacking almost all of the pressure.

Reducing sag on Reverb Stealth

Has your Reverb Stealth developed sag?
You don’t dare to use your Reverb in the winter in fear of the sag and expensive rebuild?

About 20mm of sag after riding an hour in -17C

Fear not, the sag does necessarily mean full rebuild, as it can easily be reduced with fork oil level tool (and few open end wrenches).

Myllykallio Enduro Training Center

I had a thought, that my local (500m from home) rock could act as a training place when I would not have time to go further.

Now I finally got to go route it and got a friend with me. We spent few hours routing and cleaned some rock and wood, and in the end, we had 5 new routes.

As per usual, the camera makes everything so smooth and nice 🙂

Recon Silver bushing replacement part 1: removal

My trusty RockShox Recon Silver had one broken bushing as shown in my previous post. I believed that the bushings could not be changed as 2011 Recon (Silver) manual says so, but then I heard that they could be replaced and looked into 2013 manual which did not contain the info, that lower legs should be replaced after bushing wear.

I then tried to reason between running it with the broken bushing until it breaks, taking it to local shop for bushing replacement or buying new bushing and trying to fix it by myself.

The little engineer/mechanic in me took over and soon I was googling how the bushing could be replaced. I finally found a post on mtbr.com forums that had some good stuff written by username bad mechanic . So I ordered new 32mm bushings and started gathering materials for the tools.

M12 washer seemed to be properly oversized to make the extractor tool.

Recon Silver cleanup

It was once again time remove the lower legs for cleaning. This was supposed to be simple task, but as usual, it was not.

After removing air I noticed that the travel was limited and thought could it be the damper as previously today someone told me that argyle damper was too long on his Recon Silver. Apparently the damper is shorter on 2016 models.

Fixing reverb remote with bent piston & broken bushing

Last summer I managed to ride into a pretty severe OTB (over the bar), which resulted in a few weeks break from driving, buying knee and elbow protectors and the most severe of them all, a broken Reverb remote.

From outside I could tell that the remote had a bent piston and broken bushing. After the breakage, I could still use it a little on the rest of the ride, until it leaked too much and stopped working. The leakage resulted probably because the piston head was not perpendicular to the cylinder. Normally the bushing keeps the button level and guides the (straight) piston rod and centers it in the cylinder.

When I took the remote apart I also found that there were some scratches inside the cylinder, probably due to still using the remote after the initial breakage.

RockShox Reverb rebuild (without Reverb bleed tools)

I have a 125mm RockShox Reverb (A1) in my Enduro bike. The bike was bought second hand and the Reverb had some sag and extended easily if bike was lifted from the saddle. So it was clearly in need for full rebuild but I was lazy and kept riding as it still mostly worked.

Then came winter weather with -10 degrees C, which was enough for the Reverb in its current condition and it didn’t stay up anymore. At home I took it from the bike and it had leaked oil (or something similar but more gooey) under it, no use trying to fix it by pumping more air.
