After months in storage, your bike deserves a thorough check before hitting the trails or roads. Here’s a straightforward guide to making sure your ride is safe, smooth, and ready for the Spring!
If you have any questions about the checks, please feel free to reach out on thegrizzlybearingco@hotmail.com . We’ll do our best to help you out!
Frame & Bearings
|
Check to complete |
Comments |
|
Inspect for corrosion or cracks—especially around welds, bottom bracket, and suspension pivots. |
|
|
Check all bearings (headset, bottom bracket, wheel hubs, and suspension pivots). Complete a visual inspection, looking for signs of rust. Spin/ feel for roughness or play. If in doubt, replace or service—winter moisture can cause hidden damage that can cause your bearings to fail. |
Product Tip: If you find gritty or seized bearings, consider a replacement kit. Grizzly Bearing Co. offers Bearing Kits and grease for most popular MTB brands. If you can’t see your bike, let us know and we will do our best to put one together for you.
Drivetrain

Comments |
|
Chain- Look for rust, stiff links, and stretch. Replace if worn or seized. If you have a chain checker, you can check for wear. |
|
|
Cassette & Chainrings- Check teeth for wear. |
|
|
Derailleurs & Cables- Go through index gears to ensure smooth shifting. Lubricate or replace cables if sticky. |
|
|
Bottom Bracket- Check for movement or roughness in your BB by taking off your chain, spinning your cranks and checking for play by holding both crank arms. |
Tip: A chain wear tool is inexpensive and can save your drivetrain from premature wear.
Brakes
|
Check to complete |
Comments |
|
Pads- Check for uneven wear or contamination. Uneven wear can mean that your caliper is not set correctly. Pull your brake to check for squeaking as this can show contamination. If there is no squeaking but your brake doesn’t lock, it could mean that there is not enough fluid in your brake system and it will need re-bled. Check for any leaks. If your brake is working correctly, and with your body weight you can push through the bike, your rotor may be burnt out. |
|
|
Rotors- Look for warping or excessive wear. Using a micrometer, you can check for its thickness. The minimum thickness is stamped on the rotor. If the thickness of your rotor is less than this, it will need replaced - it is worthwhile replacing your pads at the same time. |
|
|
Hydraulic Systems- Squeeze levers—feel for firmness. If spongy, bleed the system. Visually check the brake hose for damage. |
Safety Tip: One noise that you shouldn’t ignore is noise coming from your brakes. If it’s something that you can’t solve by yourself, check in with your friendly, local bike shop or friendly, local mobile bike mechanic as soon as you can.
Wheels & Tyres
|
Check to complete |
Comments |
|
Tyre Pressure- Inflate to recommended PSI. |
|
|
Sidewalls- Inspect for cracks and cuts. |
|
|
Wheels- Spin to check for play and loose/ snapped spokes. Also, check for cracked nipples. |
|
|
Rims- Check for cracks or dents. |
|
|
Tubeless Setup? - Replace sealant if you’ve been using it for over 6 months or the sealants own specification. |
Product Tip: New season? Best time to treat yourself to new tyres. Out with the old and all that!
Suspension
|
Check to complete |
Comments |
|
Manufacturer- Check their requirements on when this should be serviced. To guarantee your warranty, many require that servicing be complete every year or every so many miles. It’s worthwhile double checking this. |
|
|
Seals & Stanchions- Wipe down and check for oil leaks or pitting. |
|
|
Function- Compress and rebound—listen for odd noises. Check rebound adjustment is working correctly. Check lock out is functioning. If you have an air chamber, set it to your correct rider weight. |
Tip: Clean stanchions after every muddy ride to prolong fork/shock life.
Contact Points
|
Check to complete |
Comments |
|
Saddle, grips, pedals- Check for damage, play, or wear. |
|
|
Bolts- Check all bolts are torqued correctly. |
Product Tip: If any contact points feel off, replacements are a cheap way to improve comfort and control.
Accessories
|
Check to complete |
Comments |
|
Lights, reflectors, and bell- Confirm all are working. |
|
|
Spare tube, pump, multitool- Restock your essentials including any tubeless repair kits if required. |
|
|
Helmet- Check for any obvious dents or cracks. If you’ve had your helmet for more than a couple of years, then it may be time to replace to ensure maximum safety. |
Final Tip
If you spot anything questionable—especially with cracks, bearings or suspension— please don’t risk it. Replace the worn parts or consult your local, friendly bike shop or local mobile mechanic. Regular checks mean fewer surprises and minimizes the risk of damage to expensive components and of course, improves your safety.
