All protection kits have a few options to select before adding them to your cart. Below is a description of the nomenclature used throughout the site and products. Option 1: ModelThe model names are listed as the manufacturer website as much as possible. If you are looking at your bike on the manufacturer website and it says 'Nomad' then start by looking at the options for 'Nomad'Each model has some information within the brackets. Something along the line of '(27 - A)'. The first term is the wheel size, as some models come in varying wheel size. . . 29 for 29' wheels, 27 for 27. 5' wheels also known as 650b, 26 for 26' wheels, etc. The second term is frame construction. . . C for Carbon, A for Aluminium, S for Steel. We look and label the kits based on the construction of the Front triangle; some bikes may have a combination of Carbon and Aluminium front and rear triangles, in this case, we will mark the construction of the front triangle, be certain to cross-reference the Model name to ensure it matches the construction of your bike. So, a model listed as 'Nomad (27 - A)' Refers to the aluminum frame construction Nomad with 27. 5' wheels. Option 2: YearThe year option refers to the model years where the frame design was sold. Typically model year starts a year after the actual year the bike was introduced, for example, the Specialized Enduro 2020 was released in August of 2019, however, its model year is referred to as beginning in 2020. If the model is current, the introduction year will be followed by '- present'So the brand new Specialized Enduro S-Works has year options 2020 - Present and 2017 - 2019 for the previous frame model. Again, we do our best to match how the manufacturers label their bikes. On some models, we have added additional monikers to the year selections to further aid in the correct association to your bike. For example, Santa Cruz has 'V3' or 'V4' used to unofficially describe some of their bikes. We do our best to keep our thumb on the mark for the different years, be sure to do the research surrounding your model to see if there has been a recent change to the frame geometry. Option 3: SizeThis is your bike size. Most brands utilize the S - XL monikers, however, some brands are moving away from this. We match as best we can to the size options as listed on the manufacturer's website. Option 4: FinishThis option lets us know whether to produce your kit in Gloss or Matte. Gloss is very shiny/polished. Think of that new car shine. Matte, sometimes referred to as satin, is dull/not shiny. Different manufacturers use different degrees of matte, so not every matte will match perfectly. We have produced our films to match the widest range of matte bike finishes.  We only list models, years, and sizes that we have available. If yours is not listed at any of these levels, then we do not currently have the matching kit for your bike. Other models, years, and sizes will not fit your bike. If this is the case, please put in a kit request and we will explain the options available to you as well as try our best to source a bike to design. Read more on this subject here.
