Are 29-Inch Mountain Bikes Obsolete Now That 32 Is Coming?

No—29-inch mountain bikes are not obsolete. They remain the industry’s most developed large-wheel platform, with proven performance, broad sizing and unmatched replacement-part availability. The arrival of 32 creates a new option; it does not erase the value of a good 29er.

Riders specifically following Trek’s move into the category can use Biket’s Trek Superfly 32 South Africa hub for authorised launch and availability updates.

New technology does not switch off old performance

Your 29er’s geometry, suspension and tyres work exactly as they did before a 32-inch bike was announced. A new platform can be better for certain riders without making every previous bike bad.

Why 29 will remain strong

• Huge tyre, rim and wheel choice.
• Proven XC, trail, enduro and downhill geometry.
• Frames available across a very broad size range.
• Established workshop knowledge and spares.
• A deep new and second-hand market.

Where 32 may take market share first

Cross-country and marathon racing are the logical starting points because momentum and rollover directly affect speed. That does not mean every trail, enduro or smaller-sized bike needs the same wheel diameter.

Should you sell your 29er?

Sell it if it no longer fits your needs, not because of internet panic. Early selling can mean giving up a proven bike before production 32-inch pricing, fit and real-world advantages are clear.

Should you still buy a new 29er?

Yes—especially when the bike fits, the value is strong and you can use it now. Current 29-inch stock may offer better model choice and pricing than a first-wave product with limited allocation.

Resale value

Some premium XC buyers may shift attention to 32, but resale depends on far more than wheel size: model, condition, specification, size, maintenance and purchase price all matter.

Frequently asked questions

Will 29-inch tyres disappear?

There is no credible reason to expect that soon. The installed base is enormous across multiple mountain-bike categories.

Will Trek stop making 29ers?

Final future ranges should be judged from official announcements, not assumptions. Different categories may follow different strategies.

Is a discounted 29er a good buy before 32 launches?

It can be an exceptional buy if the model and size suit you. Value is determined by performance and price, not novelty alone.
