This area will contain information on how to keep your machine running as smooth as possible. Look for regular updates and a Q and A section to follow.

Here is the clinic handout.

Tech Tip #1 - May 22/03 Clean that Machine - It is very important to keep your bike as clean as possible. Dirt is one of the key ingredients in wrecking bike parts. It works its way into the moving parts, and acts like sandpaper to wear chains, brake pads, rims, brake pivots, cables, bearings and so on. After every ride (okay, as often as you can) you should wash your bike with mild soap and water, using a toilet scrubber-type brush. (Warning: use a new scrubber, just for your bike). Hose the soaped up bike down with gentle pressure. Pressure washers are fast, but push water where it might not normally get (ie bearing assemblies). Let it dry, then throw on some lube on your cable and chain, to keep it running smooth. A clean bike is a pleasure to ride, so keep it clean people!

Tech tip #2 - June31/03 Listen to your bike - It pays to pay attention to the noises your bike makes when you are riding. Today's aluminum frames tend to amplify noise, so they are much easier to hear than before. Creaky Cranks are the number one offender out there. If you hear noise in that area, get it checked right away. A loose crank or bottom bracket (crank bearing assembly) can be badly damaged if ridden loose. Loose spokes are also a big problem. These can make tinking sounds in the rear wheel area, and may make the bike feel wobbly. If not tightens they can lead to broken spokes or a taco shaped wheel. Grinding hubs are a sure sign of trouble, at this stage, they are probably beyond repair, and will need to be replaced. This is why getting them repacked once a year is a great idea. They most common noise heard is a squeaky chain. Lube, lube, lube. Ticking gears are a sign your derailluer is out of adjustment, or your hanger is bent. Suspension bikes are a whole new ball game. There are a lot of moving parts, so there are more places to creak, groan, and snap. Make sure all of your pivot bolts are snug every few rides. As a general rule, never ride anything loose. It will cause damage, some of which can be costly. A lot of suspension systems use dry bushings or sealed bearings. Resist the desire to lube these, as the oil or grease you use will only attract dirt and grime in places you don't want it. If you aren't sure about a noise you hear, make sure to bring it to an expert to make sure it isn't a problem. Better safe than sorry!

Tech Tip #3 - May 31/04 Maintenace Schedule - There are several part on your bike that should be serviced on a regular basis. Most of the recommendations below are based on regular use (3-4 days a week). Fork - Depending on the type of fork, some for of servicing should be done anywhere form every 30 to 100 hours of riding time. For some forks this means changing grease or oil, and possibly seals. Check your owners manual to find out what is recommended for your fork. Hydraulic Brakes - It is a good idea to flush the lines on your hydraulic brakes once a season. Moisture and particles from the calipers can gum things up, so it is a good idea to get some clean fluid in there. Bearings - Your wheel, bottom bracket, and headset bearings should be cleaned and regreased once a season, to ensure there is no excessive wear in these areas. If you let it go too long, it could mean having to replace parts that are costly. Cables - You should replace your shift and brake cables once a year, or based on wear. Most cables have smooth linings that wear out, and result in metal on metal friction. This prevents smooth shifting and braking.
