4. Drivetrain wear

General component wear is  a common issue and if it is high performance such as Dura Ace or Super Record, they will wear more quickly. We tend to advise downgrading the high wear components and retaining the controls and the deraileurs, alternatively keep your very best kit for better conditions.

Another solution is to replace chain and maybe cassette more often and thereby extending the life of chainrings, as long as the wear isn't excessive. 

We are asked on a weekly basis how long a component will last.  The life of a drive train component will vary dependent on gear selection, riding style, mileage and maintenance.

Cross-chaining is a big factor, many people riding around in big rings and wearing out chainrings, stretching the chain and even the rear derailleur, this can be more common with stronger riders using compact cranksets – most people just ride around in the big ring, riding it as a 1x. In addition - jockey wheels wear on a regular basis.


5. Seized/snapped components

Seized seatposts are something we discover regurlarly. It might not seem a big issue if it’s in the right place, however, the solution is to make sure that components are regularly greased with the correct agent for the component.  

The first thing we do, before assesing a bike is to check the seat post height before installing a workshop seat post and saddle; this prevents expensive seat posts being scratched during any maintenance work and test rides.

Cable snapping is common. Often when the entries to cable routing ports aren’t sealed properly or cables aren’t greased, excess wear can occur.  Cyclists perservere with cables that aren’t working properly and frayed at a bend in the routing, eventually they snap and are more difficult to remove.


6. Power meters

This is often a case of a lack of understanding in how they work and care in maintaining them; not keeping firmware updated on the power meters or not updating the software on their head units or installing batteries the wrong way round and not replacing rubber seals.

Often faults in this area can be resolved by reading the instructions on these expensive hi-tech pieces of kit.  We are constantly keeping ourselves updated and informed as should the user.
