Shimano XT M8120 1x12sp MTB Groupset features

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 Shimano XT M8120 1x12sp MTB Groupset.

The first thing is material. Looking at what Shimano XT M8120 1x12sp MTB 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 Shimano 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.

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.
