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.

Checking the bearings on Specialized Hi-Lo hubs

I have reused the original hubs from my 2011 Specialized Enduro Comp as rebuilt wheels with SixPack Racing spokes (double butted, 2-1.8-2mm) and Stans Flow Mk3 rims.

I thought that the bearings could be smoother and decided to take apart the hubs and check what kind of bearings they have.

1st step was naturally to take off the brake disc to prevent any contamination. Continue reading “Checking the bearings on Specialized Hi-Lo hubs”

GoPro mount adapter for bicycle lamp

It is best to have as much light as possible when mountain biking in the dark. Mostly this means to have at least two reasonably powerful lamps, one in the handlebar and another in your helmet. The one in the handlebar should point pretty close to give you peripheral visibility in front of you while spotting the route ahead.

I wanted to have some easy mounting solution for my helmets and GoPro mount was an easy choice as I already had some mounts on my helmets. I started working with an J-buckle as it already has holes in it for easy screw attachments.

I then took a small piece of 20mm electrical tubing and attached it to the mount. First try revealed that there was a small clearance issue between the rubber band on the lamp and GoPro mount.

Doval 34T fixed OCP 16% oval

After using the 30T oval on my 29er hardtail, I was convinced of the benefits that the oval chain ring brings to mountain biking: easier to rotate the cranks (no stalling) and the added traction from the lack of pulsating power on climbs. On other situations I didn’t even take notice that I was riding oval chain ring, that’s how natural it is to pedal!

So I naturally wanted an oval chain ring to my newly acquired 26 inch Specialized Enduro Comp (2011).

Toothpaste to restore headlights? ***MYTH CONFIRMED***

The headlights in my car were in pretty bad and blurry condition and I even thought about buying new ones. I had previously tried to clean them with soap, alcohol, etc. but with zero to none results.

Then I decided to try to find if the current ones could be restored and after a short google, I found several different kits to clean and polish the lights and then some instances about toothpaste.

could toothpaste really cure the lights?
