For so many years shops have been going off passed down knowledge saying that derailleur hangers on bicycle frames can not be bent or they will be too weak. This is not true and in fact it is the cause of the vast majority of shifting issues. First thing to fix with shifting is the derailleur hanger alignment. Also be sure to checkout our podcast videos at the Road Is Dead Podcast Channel: www....

After years of being asked to teach this I have finally made a video to show how we glue our tubulars here at PSIMET. Biggest thing you will notice is that unlike everyone else who tries to teach this I immediately state that there is no single method that has to be done in order for it to work. The fundamentals have to be followed. 1. Surface prep for the rim and the tire. 2. Quality and age o...

Introducing the PSIMET X Rim system. Designed to gain the most you can from Racing Cyclocross these rims are wider and use the entire tire gluing surface providing roughly 60% more actual contact between rim and tire than most other popular cyclocross rims.

Certain bikes have a tendency to show their flaws over time through use. Problems that no one thought would happen just end up sprouting up. Usually the feedback gets back to the manufacturer and is addressed in future iterations. This problem is particular to Trek Boone bicycles used for cyclocross and gravel racing and use. I have had multiple riders over multiple years come to me complaining...

Shimano Mechanical STI levers have almost always had a big Achilles here in their design. The routing through the shifter lends itself to adding a lot of stress on to the cable inners. This leads eventually to total cable failure. With it happening twice to riders I know in the last 4 days I figured I’d talk about what the early signs are and what really happens.

I discuss the most common methods of tubular glue removal - we cover hot to determine if the tire needs to be re-glued in a previous video - ua-cam.com/video/om-srNuxHI8/v-deo.html Covered are techniques used by many as well as what I have found to be our most effective technique. I also quickly discuss and review using Carogna Remover from Effetto Mariposa.

There are 4 major types of flats you can experience when using inner tube style bicycle wheels. These are the same for top end clinchers as well as big box kids bikes. 1. Puncture 2. Rim strip failure 3. Pressure failure (long rip from tube creep from improper installation or from tire sidewall or bead failure) 4. Pinch flat (snakebite) The video covers why we line the label of the tire up with...

Since it came up in the shop I figured I would share it. When facing surfaces on a bike - bottom brackets and even disc brake mounts - the use of a layout fluid is extremely helpful. If you don’t have layout fluid around then simply grab something every shop has - a Sharpie. I show you how.

Many people are told they need a bed chain when they go to a bike shop. Some of those people feel like it’s a gimmick that shops use to drum up sales. The reality is that chains wear faster than you’d think and letting their wear go unchecked could lead to hundreds or thousands of $ in repair and replacement costs. Most chains are between $15-$100 making it a fairly inexpensive way of keeping y...

Most of the time the instructions from the OEM regarding how to set up front derailleur don’t take into account mixing component types and groups or even take drivetrain wear I to account. If you’ve been dropping your chain a lot when shifting the front and have even taken it to a lot of places but it still has problems. Having a hard time even getting a “professional” to get it working? Tired ...

We cover what has to be the most common failure of SRAM Road Hydraulic (Hydro-R) brake systems. This includes master cylinder removal and lubrication as well as lubricating and fixing stuck pistons. UPDATE: Some friendly information from some key people who would know was passed on recently. Things to consider - please wear safety glasses when working on SRAM Hydro systems. The master cylinder ...

A common issue with SRAM road (and cyclocross) systems is that they are highly susceptible to failing to shift Into the smallest cog. All sorts of things can cause it to happen initially but here we show you the tricks we’ve learned from having to deal with it for years. Interesting to note - this bike, after the fix, won state championships 2 days later.... in a sprint to the line. This kind o...

We give some tips and tricks for dealing with tight tire and rims. More rims are becoming tubeless ready and many riders have a problem changing tires or changing tubes. We discuss techniques to get the tire deep into the rim channel as well as discussing what rim strip you should be using on tubeless ready rims to make it easier to change flats

We take a moment to look into what kind of difference upgrading an already high quality bearing like a German made Bearing to a Kogel Ceramic for applications such as high performance and track. Specifically we look into removing internal seals and breaking in the bearings before we even build the wheels we build. PSIMET builds high performance track wheels for training and racing. We are curre...
