Autumn Blog Series: Episode 4: Choosing Replacement Bearings for Autumn/Winter Riding

You've learned what bearings are, why Autumn destroys them, and how to spot the damage. Now comes the practical question: when it's time to replace bearings, which ones should you buy?


Not all bearings are created equal, and autumn/winter riding demands more from your bearings than summer ever does. Here's how to choose replacements that will survive the conditions.

🍁 The Four-Tier System: Understanding Your Options 🍁


At The Grizzly Bearing Co., we offer a four-tier pricing system because different riders have different needs and budgets:

Grizzly Standard - Budget-friendly option, basic seals, standard grease. Good option for hubs, bottom brackets etc. but not pivots (although can be used if not being used regularly or are being replaced often).

Enduro Standard - Step up in quality, better seals, improved corrosion resistance. Again, perfect for hubs and bottom brackets but not ideal for pivots.

Grizzly MAX - Inner race removed to increase the amount of balls in the bearing for increased strength, premium seals, MAX specific grease. Ideal for pivot bearings but not for high speed applications like hubs and bottom brackets. 

Enduro MAX - Top-tier performance, advanced seals, maximum corrosion protection
The difference isn't just price—it's how long they'll last in autumn/winter conditions and how they perform under load.  Ideal for pivot bearings but not for high speed applications like hubs and bottom brackets. 

🍁 Seals: Your First Line of Defense 🍁

As we covered in Episode 2, the seal is your bearing's first line of defense against the outside world. In autumn, that world is particularly hostile.

Seal types matter:

Rubber seals (2RS) create a tighter seal and better contamination resistance but slightly more friction. These are what you want for autumn/winter riding—especially on frame pivots, bottom brackets, and headsets that take direct contamination.


Premium seals such as LLU/LLB (found on Enduro Bearings) use advanced materials and designs that balance low friction with maximum protection. They're engineered by Enduro specifically for harsh conditions.


For autumn/winter riding: Choose rubber-sealed (2RS) or premium sealed bearings. The slight friction increase is negligible compared to the protection you gain.

🍁 MAX vs. Standard: What's the Difference? 🍁



You'll see "MAX" and "Standard" options throughout our range. Here's what that actually means:



Standard bearings have a full inner cage. The bearing balls retained by the inner cage. 




MAX bearings have the inner cage removed. This means that the bearing can contain bigger and/or more balls contained within the same bearing dimensions, which means:
  • Increased load capacity (stronger)
  • Better durability under impact
  • Longer life in high-stress applications

 

Where MAX makes the biggest difference:
  • Frame pivot bearings - They handle suspension loads and impacts

 

Where Standard bearings are optimal:
  • Hub & Bottom Bracket- Higher speed, lower impact loads
  • Pedal bearings - Easier to service regularly

🍁 Grizzly vs. Enduro: What's the Difference? 🍁


Both Enduro and Grizzly are quality products, but there are differences:

Grizzly Collection:
  • These are, generally, unbranded bearings that we stock that conform to high standards e.g. the MAX Bearings are ABEC 3 and Standard are, at least, ABEC 1. Depending on stock levels, you may receive branded bearings or bearings that are of a higher ABEC precision.  You'll never receive an ABEC rating lower than given above.
  • Excellent value for money
  • Available in Standard and MAX configurations
  • Good seal technology and corrosion resistance
  • High quality grease.

 

Enduro Bearings:
  • At least ABEC 3 Precision
  • Premium brand with advanced seal designs
  • Proprietary seal technology (LLB, LLU, etc.)
  • Wider range of specialty bearings
  • Maximum corrosion protection

The truth: For most riders in most conditions, Grizzly bearings perform excellently. The quality difference exists, but it's not night and day. Enduro bearings are the choice if you want absolute maximum performance and longevity, ride in extremely harsh conditions, or race competitively.



For autumn/winter riding: Either brand will serve you well if you choose the right Standard or MAX configuration where appropriate. Your cleaning and maintenance habits matter more than brand choice.

🍁 Grease: Your Best Friend 🍁


Even the best bearing won't last if the grease inside fails. And in autumn/winter, grease faces serious challenges.

What good bearing grease does:
  • Resists water washout
  • Maintains consistency in cold temperatures
  • Contains corrosion inhibitors
  • Stays in place under load
Our recommendations:

Enduro MAX Bearing Grease (GR-009) - Premium option with excellent water resistance and corrosion protection. Formulated specifically for bicycle bearings in harsh conditions. For MAX Bearings Only.

Enduro Performance Grease (GR-008) - Premium option with excellent water resistance and corrosion protection. Formulated specifically for bicycle bearings in harsh conditions. For all standard bearings (non-MAX).

Peaty's Speed Grease - High-performance bearing grease with strong water resistance. Great all-rounder for autumn/winter use.

For autumn/winter riding: Use a quality bicycle-specific bearing grease with water resistance and corrosion inhibitors. Cheap automotive grease won't cut it in UK autumn conditions.

🍁 The Subscription Model: Full-Sus MTBs 🍁


Bearings aren't forever—especially in autumn/winter. Our subscription model is designed for riders who want to stay ahead of bearing wear rather than react to failures.  In all cases, the subscription replacements are in line with the period of replacement advised by the brand of your bike or the Industry Standard.

How it works:
  • Choose your bike brand and model
  • Select your bearing kit and replacement interval (6, 9, or 12 months)
  • Receive fresh bearings automatically at your chosen interval
  • Save money compared to one-off purchases

 

Who benefits most:
  • Riders who put high mileage on their bikes
  • Year-round riders facing constant wet conditions
  • Riders who've experienced bearing failures and want to prevent repeats

 

For autumn/winter riding: A 6-month subscription interval makes sense if you ride through autumn and winter regularly. Fresh bearings going into autumn, fresh bearings coming out of winter.

🍁 Matching Bearings to Your Riding 🍁


Casual rider (1-2 rides per week, mostly dry rides):
  • Grizzly Standard or Enduro Standard bearings
  • Replace when you notice roughness or play
  • Service annually with fresh grease

 

Regular rider (3-4 rides per week, mixed conditions):
  • Grizzly MAX bearings for pivots and Grizzly  Standard for everywhere else
  • Replace pivot/BB/headset bearings annually
  • Consider 12-month subscription

 

Year-round rider (4+ rides per week, all conditions):
  • Enduro MAX or Grizzly MAX bearings in pivots
  • Enduro Standard in hubs/ bottom brackets
  • Replace pivot/BB/headset bearings every 6-9 months
  • Consider 6-month subscription

 

Racer/aggressive rider:
  • Enduro MAX for pivots and Enduro Standard for everywhere else
  • Replace pivot/BB/hub bearings every 6 months or after big events
  • Service between replacements

 

A quick note about Headset Bearings - Autumn/ Winter can be harsh on these but salty sweat is an enemy too.  When choosing a Headset Bearing Replacement have a think about how much your headset is exposed to sweat i.e. road cyclists may expose their headset to more salty sweat than a MTB-er.  

 

If you think sweat could be an issue for you, then we'd advise to opt for a headset bearing that is made of Stainless Steel. We, currently, stock Enduro Stainless Steel Headset Bearings for this purpose. If you find the cost prohibitive, then Black Oxide would be the next choice (followed by Chrome Steel).  

 

Opting for a more budget friendly headset bearing would only require you to maintain or replace the headset bearing more often.

🍁 The False Economy of Cheap Bearings 🍁


We've all been tempted by £20 bearing kits on eBay or Amazon. Here's why they're rarely a good deal:

Cheap bearings typically have:
  • Poor seal quality (water gets in fast)
  • Inferior grease (washes out easily)
  • Loose manufacturing tolerances (rough operation, short life)
  • No corrosion protection (rust quickly in UK conditions)

 

The real cost:
  • You'll replace them three times as often (or more)
  • They can damage frame/hub surfaces while failing
  • Time and effort installing bearings that won't last
  • Potential safety issues if they fail catastrophically

 

A £40 quality bearing kit that lasts 12 months is cheaper than a £15 budget kit that lasts 3 months.

For autumn/winter regular riding, cheap bearings are a false economy. The conditions are too harsh, and the consequences of failure too expensive.
