Chain wear is a common problem on high use bikes or on bikes that are not cleaned often through the winter.
One problem that Greg see’s regularly on bikes that come in to Doctor Sprockets Workshop particularly in the winter can be chain wear caused by a lack of cleaning. Road dirt mixed with chain oil creates an oily gritty paste similar to grinding paste. This can reduce the life of you chain dramatically.
The answer is to clean your chain and oil it again particularly if you have been out on the winter lanes where there is mud and lots of other nasties to get inside your links.
Chain wear symptoms can be many. Slipping or skipping gears is one characteristic of chain wear. Others include clicking from your bike gears chain slop, chain suck (Chain sticks onto the bottom ring) and of course the risk of the chain snapping is higher on a worn out chain.
You can get a simple tool to check chain wear which drops into the chain to give an indication of the amount of wear. The tools are inexpensive and should be part of your bike tool kit. Greg use’s a chain wear tool on every bike that comes in the workshop.
Once you have cleaned your bike chain it is really important that you lubricate it to keep it running smoothly and prevent it rusting. Studies have shown a well oiled chain creates less friction and slightly more power and therefore on a longer ride makes things easier. A couple of minutes spent oiling your chain will pay dividends up the road.
So what oil should I use on my bike chain?
There are so many oils on the market that it makes it practically impossible to choose! There are many great bike chain oils and some that are not so good. A look around the shelves in your local bike shop or in one of the online stores such as Wiggle will give you a great choice.
Greg always uses wet lubricant ( suitable for wet weather and the UK climate) when oiling chains in Doctor Sprocket’s Workshop. Light spray oils with PTFE are great for the rest of you bike but given the changing weather in the UK a wet lube is the way to go.
Muc OFF , Finish Line, White Lightning, Lifeline are some of the products we have tested in the past. We use Finish Line products from our own experience which all round have been great.
How do I oil my bike chain?
Most of the wet lube oils come in a bottle that you can squeeze gently to dispense the oil onto the chain. When servicing bikes in Doctor Sprocket’s Workshop we use bike stands to hold the bike but you can easily do this with the bike on the floor. The key s to be able to rotate the crank ( and therefore the chain) backwards whilst holding the bike steady and applying the oil at the same time!
So it sounds difficult but it really isn’t… If you have a friend to help you it is worth two minutes of their time… If you are on your own hold the back wheel between you legs to keep the bike steady. Hold the wet lube bottle in your roght hand and put it on the centre part of the chain as you look from the top. You are trying to get the lube to drip between the roller and the side plates of the chain which will lube the roller and the pin running through the link.
Pedal the left crank backwards and slowly apply the wet lube letting it soak in a little. Ride your bike around and change up and down the gears as this will oil the cassette sprockets before wiping off any excess wet lube off the chain with a clean dry lint free cloth. Take care not to get any lube on your braking surfaces when you oil your chain.
Greg recommends you oil your chain before every ride even if the chain is dirty. It is better to oil it than not.
Greg runs a professional bike fitting service from his family run business based in Wallasey on The Wirral in the North West of England.
He breaks his customers down into a few categories each coming with a specific desire in their cycling.
Triathlete’s looking for the most comfortable position in the aero tuck. Getting the right balance can increase power and conserve energy at the same time. Longer distance Triathlete’s can see some remarkable gains.
Newcomers to cycling who want a bike fitting before they start riding. Greg say’s that this is the most sensible option rather than setting the bike up yourself due to the number of variables which include shoes, cleats, pedals, bar height and angles, saddle height, saddle rake and reach to name but a few. A good bike fit can prevent injuries, help to reduce fatigue and give a more comfortable rider experience.
Club racers who may have been riding years and never had a bike fit. They may be looking for edge to increase power and speed or endurance. Many riders in this category may come for a bike fit due to injury.
There are so many ways to determine the correct saddle height. Some are more precise than others but one thing that advocates of each method all agree on is that if you get it wrong the effects can be highly detrimental.
A saddle height that is too high can cause pain and problems with joints. It can also cause ligament and tendon issues due to overextension.
A saddle height set too low can greatly decrease your stamina by over 10% and lower your overall power output. The key is getting the right saddle height which will increase your power at the pedals and give you far more comfort particularly on the longer rides.
Most riders that Greg see during a professional bike fit at Doctor Sprocket’s Workshop in Wallasey have their saddle height too low. This is a common mistake and one generally caused by the simplified method used to try and work out the correct height.
As part of your bike fit for your road or tri bike Greg will use a goniometer to measure the angles to see that they are set at an optimum level for your body and frame.
There are 4 points of contact with your bike. Two of these are your cleats and more specifically where they attach to the pedals. They are the first crucial part of your bike set up and can cause a drop in performance at best and at worst pain or injury if they are not correct.
If you imagine your legs are the pistons delivering the power to the pedals and propelling you forward. A piston is designed to move in a straight line to give the best performance and this is exactly what your legs need to be doing.
All bodies are made differently by their very nature. Legs can be shorter, knees can move in different plains, ligaments can be tighter on one ankle and so on. There are a vast amount of reasons why you may feel something is wrong with your cleat position.
The good news is adjustments can be made to get your knee over the pedal and pumping in a straight line.
Cleats can be moved in numerous directions. The fore and aft movement of the cleat accounts for the main issues that Greg see’s during a bike fitting. Other reasons may be due to the rotation of the cleat or the inboard / outboard set up which can effect the movement of the knee and hip.
Modern cleats can have some float (sideways movement) built in but it is crucial that your cleats are set correctly in the first place. Greg advocates an initial neutral set up with most people after an assessment of your natural stance.
That said for people who are duck toed either in or out to any excess cleats may be adjusted to compensate for this. It is not unusual to see each shoe and cleat set up differently.
