Quality

Quality is without doubt one of the most important factors that we consider when buying bikes, parts, accessories or clothing. As you’d imagine it’s especially important when buying Groupsets. Let’s take at a look at the sort of things you can look at when trying to ascertain the quality of Box Three Prime 9 Speed Drivetrain Groupset.

The first thing is material. Looking at what Box Three Prime 9 Speed Drivetrain Groupset is made of will give you a really good idea of the quality overall. Take a look at the specs above and you should be able to see the material. It’s then up to you to decide if it meets your expectation.

Similarly you’ll also want to spend some time looking at the features too. Again the table above, listing the features will give you a really good overview. However you should think about the sort of features that you’d expect when buying new Groupsets. It’s worth writing a list of the “must-have” features so that you don’t end up compromising and missing some important features, or alternatively end up buying an unnecessarily high specced product.

There’s also a lot of merit in checking out the brand of the product and looking at the various brands that are selling Groupsets. Brands like Box are of courses extremely well respected in the cycling community so you know you’re getting a fantastic product with them. But if you’re undecided on your product you should write up a list of brands that you’d be happy to buy. It’s a great way of filtering and narrowing down the number of products when you’re searching.

Next up you’ll want to think about the price and use that as a guide to set your expectations of the quality. If you’re buying the cheapest of the options in the Groupsets category you should probably expect it to not be of as good quality as the most expensive. It sounds obvious of course. But this is where you can get a bit clever and use your combination of features, specs, materials and other factors to work together to get a really good quality product at the best price. We often draw up a list of “must-haves” and use these as filters when shopping online so that you’re only seeing products that meet your criteria. You can then sort by Price>Low to get the best deals.


Comparing Prices

Price, as you would imagine, is the most popular reason for someone buying one product over another. It is the single most important factor in choosing the majority of products we buy. The same goes for Groupsets.

It’s at this stage of the buying process, when you’re looking at different options, that you should set a budget. Do some research to understand how much roughly you can expect to pay for the sort of level of product that you’re looking for. Then match that to your own personal circumstance and how much you can afford to spend. This will really help you in narrowing down the right product for you.

Box Three Prime 9 Speed Drivetrain Groupset Reviews

Reading reviews is an amazing way of getting a good feel for a product without actually being able to try it or see it first.

There are two different types of reviews, and we also recommend reading both.

1. Expert reviews – In the cycle industry there are loads of really reliable trusted resources for expert reviews. For example if you’re looking to buy a new bike, BikeRadar Bike Reviews are great.

2. Customer reviews – these are probably your best resource for information. There’s no finances or influence involved, they’re purely just honest reviews from customers that have bought and used the product. The reason we love customer reviews so much is because no matter if their view is good or bad, there’s a very good chance that it will be honest and unbiased.

  • Description: Box Three Prime 9 Speed Drivetrain GroupsetThe Box Three groupset offers the same capability as its top-tier siblings but it’s built around a simpler platform. The cassette is more accessible at 11-46T and fashioned without a spider. The rear mech exploits Box’s Limited Slip clutch technology without the Tri-pack features. This allows you to shift easily with a comparable mechanism, although you’ll forgo the hinged clamp and die-cast structure. Lastly, it’s strung together with a Prime 9 chain but without extravagant coatings. If you’re looking to bring your mountain bike into the 21st century, then level up with this group.Box Three Prime 9 ShifterThe Box Three shifter makes good use of nylon composites in both top and bottom shells as well as the levers. Box Three is our performance and value tier. So this shifter sheds all the fancy trappings of the top 2 tiers but maintains their shifting characteristics. All Prime 9 shifters take advantage of the 9-speed’s inherent durability, simplicity, and reliability. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. And the best part is? Prime 9 is also terribly forgiving so you won’t have to constantly adjust your set-up.Features: Material: Glass Fibre / Nylon Composite, Steel Extruded Clamp 2 Piece Pull Lever / Up to 3 Gears Per Shift Resin Top Shell Fast Action Release Lever Prime 9 Technology Multi Shift Option Not Intended for E-Bike Use Single Shift Option Recommended for E-Bike Use Weight: 128gBox Three Prime 9 Wide Rear DerailleurThe Box Three Rear Derailleur simplifies the features found on the Prime 9 Box One and Two rear derailleurs making for a fully-featured wallet-friendly rear derailleur.
