The role of a helmet is to keep a rider safe and, as a vital layer of protection against the hard unmoveable ground, finding one that is right for you and the type of riding you enjoy is imperative.

Helmet technology is continually evolving, from retention to ventilation plus the addition and increased sophistication of rotational protection systems such as MIPS. These features increase rider comfort and safety so that you have a better time on the trail. It is also important to remember that even if your old helmet is still serving you well it may still need to be replaced. Helmets have a shelf life and while manufacturers provide their own advice it's generally accepted that a helmet should be replaced every 3-5 years based on use as the safety and integrity of the helmet degrades over time.

Luckily for you, Bike Perfect has been hunting down the deals so that you can replace your old faithful helmet with a new shiny head protector. Check out our pick of the best mountain bike helmet deals currently available or if you want to have a hunt for a cheap MTB helmet yourself we have put together a list of all the best places to find them.

Haven't found what you want?

Below, we've put together a roundup of the retailers where we regularly find great deals. If our selection of deals picks haven't supplied you with what you need, we won't just leave you hanging. We're happy to provide you with the tools to help you find your own. While not all of the following retailers sell bikes, they all cross over into the world of cycling in some way or another, be that by selling clothing, components or tech. 

Competitive Cyclist is one of the largest cycling retailers in the US. Their cycling sale is ongoing and there are deals aplenty. 

BackCountry, the US outdoor sports retailer, is one of the United States' go-to online retailers for bikes, components, clothing and accessories. It doesn't limit itself to cycling though, with fishing, skiing, and even yoga in the range of sports catered for.

Jenson USA is another USA-based retailer and always has thousands of offers available.

Rei is an outdoor retailer based in the USA. There's always a sale, and you can currently get up to 64% off cycling products and even more in other categories.

Gear sells a whole host of outdoor gear, but its cycling offering is what's interesting to us, such as these Smith Optics Flywheel glasses on sale.

Gear Coop has a huge cycling section currently with discounts on Giro shoes and helmets. 

Seshday has up to 80% off in its sale. It's not all cycling, but there's a good portion of tech that cyclists of both road and mountain bike disciplines will get excited about. 

Clever Training is the go-to place for all-things fitness training. With everything from turbo trainers to track pumps, the Clever Training sale has discounts on brands such as Garmin, Suunto, Topeak and more.

Moosejaw isn't a dedicated cycling retailer, but it sells a range of venerable brands. There's a heap of bikes on sale, including hardtail, full-suspension and gravel bikes.

Eastern Mountain Sports is another outdoor retailer that also sells cycling products. You can save up to 60% on cycling gear, although they don't sell bikes. 

Tree Fort Bikes has a range of mountain bikes, gravel and road on offer, including a number of bikes from Salsa, Surly and Giant. 

Alchemy Bikes currently offering $1000 off select bikes, very limited stock left.

Walmart might be a left-field inclusion in this list - even with the Walmart family buying Rapha. We certainly wouldn't recommend a typical supermarket bike, but Walmart has a huge range of electronics, a lot of which are useful to us cyclists - such as GoPro cameras, iPads or laptops for Zwift and Garmin computers.

Wiggle is one of the world's largest online cycling shops, supplying over 70 countries with cycling deals. 

Chain Reaction Cycles is owned by Wiggle, and therefore shares many of the same cycling deals as well as an international audience.

Evans cycles is one of the oldest cycling retailers in the world, it is a British company that services the world via its online store. For even more deals, check out our Evans Cycles deals.

Amazon isn't exactly the first retailer you think of when shopping for your bike but there's little the world's largest retailer doesn't sell, such as action cameras or Garmin computers.

Tredz is another British retailer with international delivery options and a range of great cycling deals.

Rutland Cycling is yet another British retailer that operates internationally.

Tweeks Cycles is more UK-focussed, but there are still some great deals worth checking out. 

Hargroves Cycles is a retailer based in the UK and regularly discounts mountain and gravel bikes.

Cyclestore, one of the UK's lesser-known retailers, often has Specialized products at the best available price. 

Leisure Lakes is another UK retailer. With 11 stores, it's a relatively well-known franchise, and will happily ship overseas.

Halfords is discounting all sorts of cycling products. We'd probably recommend against their bikes, unless you're after something cheap and cheerful for the kids, but for your electronics and tools, you can't go far wrong.
