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 Half Aluminium Deal

Our “Big Half Deal”, the 85mm wide full carbon fat bike rim/wheel for the 27.5” wheel format broke new performance barriers for the Fat Bike. But we wanted to open up the raw technology within this wheel and offer it to an expanded market. The main ride characteristics of our Big Half Deal wheels are the lively ride, the incredible toughness, the superior comfort levels and the ease of tyre installation. By changing the rim material from carbon to aluminium with the “Big Half Aluminium Deal” we have largely kept all of these positives but can now offer them within a much more cost effective package reaching out to even more Fat Bike enthusiasts. 


Light and stiff

The Big Half Aluminium Deal rim is an aluminium construction and ultilises a ribbed, single wall design. Even when using aluminium, our advance design and construction technique mean that you’ll still save a huge chunk of weight per wheel! This ribbed cross section also 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 Aluminium Deal rims is then taken care of via “Inflatobam”, our patent pending system for installing big tubless tyres. As already mentioned, the Big Aluminium Deal rim features an irregular cross sectional shape to enhance strength but this twin channel profile 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.
