If Big Deal is big, the BFD is gargantuan.
Our more discerning customers just weren’t satisfied with an 85mm carbon rim. The bikes keep getting wider, the tires keep getting larger, and the Big Fat Deal is ready for the challenge. At a whopping 100mm wide, it can make the most of your fat bike footprint, for the ultimate in flotation over soft or powdery surfaces. At an incredibly light 500 grams per rim, the BFD is also much lighter than competitors’ skinnier aluminum rims. Combined with a tubeless tire setup, it is possible to lose up to two pounds per wheel when switching to Hed BFDs. Note that the BFD is drilled symmetrically ONLY and cannot accommodate offset frames.
Like the Big Deal, the BFD utilizes Inflatobam, Hed’s patent pending tubeless system for installing big tires. The twin channel rim design provides a better pre-inflation seal by trapping each tire bead against the rim. This drastically reduces the amount of air it takes to get the beads to “bam” into place. In conjunction with the rim shape, Inflatobam utilizes Inflatobands. These effectively provide a variable rim-channel diameter. This compensates for the discrepancies in tire bead diameters by minimizing the gap between the tire and the rim channels (the main source of air leaks). Once seated, the angled bead shelf prevents the tire from collapsing back into the rim at low pressure. Our interior surfacing and tight tolerances ensure no tire burp or slip. Also note that our rim shape does not require tire levers to remove and install tires.
The BFD is available as a rim-only, or as a complete wheel using Hed Brickhouse hubs. Customers may also send in their own hubs for custom builds (see below for further info). The BFD is built with bladed steel spokes and brass nipples.
NOTE: In order to send hubs to us for a custom build, the dealer will need to call 651-653-0202 for an RA number. Hed isn't responsible for lost hubs that are sent without an RA number. Please don't send skewers, cassettes, or other small parts that are unnecessary for the wheel build. Allow 2-3 weeks for turn around.
1. Do NOT use tire levers on BFD carbon rims!!!
2. For all types of bicycle wheels, a hard strike on the rim is likely to result in rim damage. At the point of impact, an aluminum rim will dent, and a carbon rim may delaminate - both are unsafe conditions that require rim replacement.
3. Specific to our Big Deal and BFD carbon rims: If you choose to ride these rims on regular dirt trails (e.g. NOT in soft snow or sand), wider tires and higher air pressure will decrease the chance of rim damage from striking an obstacle. We strongly recommend an honest assessment of your ride style. Use 10 psi minimum on 4" tires, or 8 psi minimum on 5" tires.
In this Hed Tech Talk, we cover the fine details of how to install tubeless tires on our fat-tastic Big Deal rims. These instructions apply to all current models that we offer: -The 85mm-wide Big Deal carbon -The 100mm-wide B.F.D. carbon -The 80mm-wide B.A.D. (Big Aluminum Deal) All of these wheels feature our Inflatobam rim shaping and technology. In the event that your tires don’t fit quite tight enough to inflate, we also include our proprietary Inflatobands with each rim, which are giant rubber bands intended to reduce the gap between your tire and rim, for easier initial inflation. If you’re old school and like to use inner tubes, you can do that too, and nobody will be mad (but you should use Gorilla Tape to cover up the spoke nipples – so you don’t puncture the tube). NOTE: You will need an air compressor for tubeless inflation. If you use tubes, a floor pump will work just dandy. BIG NOTE: DO NOT USE TIRE LEVERS ON OUR BIG DEAL RIMS! You don’t need them, and they can damage the rim. Find more Hed Tech Talks at this link: https://www.youtube.com/channel/UCj8G1vwwVp6hjvTwO1CmOxA
