Fat Bikes are one of the most fun ways to ride on two wheels. Consequently we have taken this sector very seriously and have applied our knowledge, garnered over 30+ years to create wheels that will enhance your Fat Bike ride allowing you to explore further and higher in to the wilderness.


The Big Deal

The Big Deal (B.D.) was our pioneering wheel within the Fat Bike genre and is certainly one that we are very proud of. Following extensive real-world research we discovered that Fat Bike wheels could be enhanced to a much greater degree. We wanted lighter weight for a more responsive ride but we still wanted a bomp proof construction for the roughest of trails and paths. We also wanted more comfort and we wanted an easier tyre installation process. With these main points pigeonholed we went about the design and creation process.


Light and stiff

The Big Deal rim is a full carbon construction and ultilises a ribbed, single wall design. With a weight of just 445g you can expect to shed around 600g - 900g.. per wheel! This obviously takes care of the weight saving and ride responsiveness portions of our design brief! Meanwhile, the aforementioned rib cross section goes about enhancing stiffness and strength with it’s irregular shape suring rim integrity, readying the structure for hits and bumps from all directions.


Easy tyre installation and comfort

Ease of tyre installation on our Big Deal rims is then taken care of via “Inflatobam”, our patent pending system for installing big tubless tyres. As already mentioned, the Big Deal rim features an irregular cross sectional shape to enhance strength but this twin channel shape also provides a better pre-inflation seal by trapping each tyre bead against the rim. This in turn dramatically reduces the amount of air it takes to get the tyre beads to “bam” in to place (hence the name “Inflatobam”!). In addition to this rim shape our Inflatobam technology also utilises “Inflatobands”. These bands are fitted to the internal rim section before tyre installation and effectively provide a variable rim-channel diameter. This compensates for any discrepancies in tyre bead diameters by minimising the gap between the tyre beads and the rim channels, which is the main culprit of installation problems due to air leaks. Also note that our rim shape does not require the use of tyre levers and that it is fully compatible with the use of inner tubes.


Once the tyre is seated the unique rim shape then comes in to play again as the angled bead shelf prevents the tyre from collapsing back in to the rim at low pressures. This helps to ensure no tyre burping or slipping. With the ability to run even lower pressures the increased comfort part of our initial design brief is then catered for nicely.


To complete, our Fat Bike rims are hand laced and trued to our own super silky and super strong “Brickhouse” hubs with our own bladed steel spokes and brass nipples.
