In this feature I will address bicycle maintenance, especially cleaning and how to avoid damaging your bearings while doing this. Riding for decades in Belgium and The Netherlands and now living in the Southwest US desert, I understand that the level of cleaning is not only depending on the type of riding your bike is exposed to, but also depending on your geographical location. A CX bike in Tucson, AZ probably lives an easier life than a road bike in Oudenaarde, Belgium.
How much cleaning does your bike need?
As I brought up in previous posts, bicycle maintenance is very much about being honest with yourself. Think what your prized possession has been exposed to and choose a matching level TLC. If you are a roadie in Southern California, chances are good that your bike can do with a wipe down every week or two weeks and a drive train cleaning every now and then. If you live in a wet climate and your Sunday rides will happen rain or shine, you will probably need a bucket with some brushes, a large sponge and soapy water to restore the showroom shine. Mountain bikes live a harder life and might need some garden hose treatment after a muddy ride. I know cyclocross mechanics that drive straight from the race course to the car wash to get all the muck off bike and kit.

While we never recommend power washing bicycles, in CX there simply are no options. Since the bikes get several treatments during the race already, the one after the race probably cannot do a lot more damage. The result is simple: drive home from the carwash and take the bike apart in order to remove any stagnant water from the frame, hubs and headset.
Do the minimum, but make sure it is sufficient
Once you have determined the contamination level, it is time to determine the minimum cleaning level you can get away with. It is no secret that moving parts on bicycles are no fan of water. If you can avoid using it: good. One of my favorite cleaning products for years has been Pedros Bike Lust. It is a liquid that comes in a spray bottle, perfect for taking dust off a bike, and leaves a shiny residue on your parts that actually repels dirt. It’s a weird slippery goop, so keep it off brake surfaces of rims, disks and brake pads. The goal with this minimal cleaning approach is not to cut corners, the goal is to get the bike back to showroom condition with the least amount of work.
- Pedros bike lust was my secret weapon in Belgium. I loved how customer's jaws dropped to the floor when they met their revitalized bike again.
What if you have to use water for bike cleaning?
Again, the minimal cleaning rule applies: a bucket with soapy water is better than the garden hose and the carwash should be avoided when possible. Remember that the deeper you let the water penetrate, the more time you will be spending cleaning and drying the internals of your two wheel wonder.
- Jorge Romero of the UnitedHealthcare pro cycling team shows that bicycle cleaning requires eye for detail. Small paint brushes are perfect for degreasing a drive train and not getting aggressive products all over the frame.
How to protect ball bearings during cleaning?
Trying to keep water off your bearings is the first step. Avoid spraying water directly into the headset, bottom bracket and suspension pivots is next. There are some steps you can take if you know your next cross race is going to be sloppy. Pack the outside of your bearings with a water resistant grease. When I was a mechanic in Belgium, I would take the fork out of the every bike during service and literally cover the lower headset bearing in a marine grade grease. It was a given that my customers at one point or another would be riding in heavy rain. The same can be done with bottom bracket and suspension bearings. Simply take off the covers, apply a layer of grease on the outside of the seals and put the covers back where they came from. Typically this adds a bit of friction, but nothing close to the friction caused by rusty races.
The last step is to always think about stagnant water in a bike. Taking out your crank and cleaning the inside of your bottom bracket shell is a good one, but think of the water that can get trapped inside suspension pivot points, inside brake levers and derailleur pivots. This is where compressed air is your friend. If you are the lucky owner of an air compressor, get a gun with a long nozzle and blow every nook and cranny dry. As with pressurized water, I am always afraid that compressed air will actually force water underneath the bearing seals, but I have never been able to prove this. Keep a bit of distance when aiming directly at your rotating parts.
Most cyclists care more about their bikes than many other things in life. There is a good chance you dropped serious cash when you rescued yours from the shop. It deserves the best care you can give it. Remember minimal but sufficient cleaning and prevention when you know things are going to be bad. Washing your bikes frequently will help you build up a procedure to do it thoroughly and quick. The above video of team Tinkoff Saxo shows incredible amounts of muscle memory and hand-eye coordination. Something that can only be achieved after years of repeating the same exercise over and over.
