1. Lack of general maintenance

Stay on top of keeping your bike clean and in good condition.

Keeping on top of the maintenance of your bike is the best single piece of advice any mechanic can give.  This means regularly cleaning and lubricating it to save component wear in

When a bike is sold, the buyer often doesn't know what needs to be done to keep the bike in good condition, from cleaning to storage. However, you need to learn the craft first.  If you are going to do it yourself - read any instructions or follow 'youtube' videos.  There is a wealth of information out there.  Otherwise, It can mean that even cartridge style brake pads can be fitted backwards. You should have a go, if you are confident enough but if you are unsure and it is safety related, have it checked by John or Perry.

2. Creaking bottom brackets

One of the most common problems we have come across overr the last 12 years isdreaded bottom bracket creak. 

Given the amount of specifications of bottom brackets, and their complexity, it is unsurprising

Specific tools such as a bottom bracket press to instal and a different tool is necessary to remove.  Occasionally when we complete a pre-delivery assembly, we find that the factory has not installed the component correctly.

Given the varying standards and complexity of bottom brackets, the best piece of advice is to constantly maintain the bottom bracket with every service. If you own the tools and have the time, then ensure bearings are cleaned and greased, especially after extended periods of poor weather where dirt and water ingress can be a bottom bracket’s worst enemy.  Often there’s not a huge amount you can do for them even if you do have the tools – it’s wear and tear.

Make sure bottom bracket servicing is near the top of the to do list for addressing any creaks or grinding as soon as they arise – don’t delay.

3. Disc brake maintenance

Cable rim brakes were one of the simple jobs a home mechanic could try with relative ease, hydraulic disc brakes are another story.

There’s a lack of knowledge around how disc brakes are operated and serviced, we find that mountain bikers understand it better because they’ve been using them for about 20 years.  Even to the extent of getting them to operate properly when new and the initial bedding in process.

The most common issue is from rotor and contamination on the disc followed by cross contamination onto the pad - care are needs to be taken when lubing other areas of the bike.

Rim brakes vs disc brakes

Rim brakes vs disc brakes - what’s the difference?

Traditional rim brakes apply the braking force on the outer edge of the wheel. A disc brake focuses forces on a smaller rotor, situated towards the centre of the wheel.

What are the advantages of a disc brake?

Power - Disc brakes generate an incredible amount of stopping power, usually far more than is necessary to adequately stop a road bicycle. This allows the rider to apply much less force to the lever before the bike comes to a halt. Less hand strength leads to a decrease in muscle fatigue, especially on longer descents.

Disc brake power can also be customised by exchanging the disc rotor (the metal braking surface) for rotors of differing diameters. A larger rotor equates to more powerful brake, useful for larger riders or heavier bikes.

Modulation (control) - Pulling with a specific amount of strength on the brake lever of a rim brake can result in wildly inconsistent results. When you pull on a disc brake equipped lever, resultant braking force is much more consistent. This reliability allows you to accurately judge how much force you need to apply in order to achieve the expected result. So despite it being easier to lock up a wheel with a disc brake, the feedback at the lever means you are far less likely to do so.

Disc brake advocates often state that disc brakes actually make you faster as technically you can spend less time ‘on the brakes’, allowing you to brake later before a corner and increasing the time spent at higher velocities.

Reliable, all weather braking - When you apply a rim brake in wet weather there can be a split second delay before you start decelerating. This delay is due to the brake pad displacing water and road grime from the rim to enable sufficient contact and friction. As such the actual braking force you apply in the dry might not stop you in the wet. If you have carbon rims, this is further exagerated . The location of the disc rotor, plus the generally protected calliper position normally results in very little impact to a disc’s wet weather performance.
