Hey guys! With over a year of Real Life™, Computational and Wind Tunnel testing and a couple of race wins now under our belts, i figured i should actually declare them out of BETA testing and make a sales thread for the HubSinks, im super humbled by the help i've received from everyone during the beta stages and for everyone whos running them on their bikes so far, hopefully i've helped contribute a little to a community that's given me so much fun!
I'll keep this thread simple as all the information you can ever need is in the '"Definitive Tests on the Heating and Cooling of Hub Motors" thread (link below) and i would love to invite people running the HubSinks to share pics of their rides in the thread also!

In short, the HubSinks have been proven to vastly improve the thermal management and power handling of hub motors allowing much higher power levels and/or endurance to be achieved with higher motor efficiency due to lower copper losses, especially when combined with Grin's Statorade.
if your hub motor is overheating or thermal limiting, or you are planning on running substantially more power than stock the first thing you need to do is install Sinks and FF, detailed information on their performance can be found here - http://www.hubsink.com and here https://dl.dropboxusercontent.com/c...3l5vYdfKtiLegkWbVBMLPD66vMyOVJfFhP6YjWan/file

Andy Braidford - It took 10 minutes to install, and well the information speaks for itself. Looks good, easy install, better heat shedding.. what more do you want. Cheers guys!

Just gave my bike an absolute hiding. Now running ff and hubsinks. Adaptto on boost with ovs 3 at 120amps. Temp here is mid 30's and i tackled the same route i did in my first test with just hubsinks. Air temp is around 10 degrees cooler. The motor temp stayed cool... really really cool. Was running about 30 degrees cooler on the same hills, but was going faster. Not only does the motor run cooler but the motor seems much more powerful at lower temps?? It feels like an absolute animal now. Does anyone know if torque goes down as motor temp goes up? I then went in search of something harder in the national park. The absolute hottest i could get was 90 in bush. That was going up a dirt road, up a big hill- maybe 2km long, full throttle. I just couldnt get it up to the same temps as it used to run pre- ff and hubsinks. Along the single tracks i couldnt go that fast because of all the turns, front wheel spent alot of time in the air, its a real blast to ride, in these parts it was down in the 60's Final heat test I did was a simple brute speed run. Max power, over 100 for a nice long flat stretch for around 7-8km. Peak temp 95. All up i did around 80km of testing mostly on dirt and nearly had a few big stacks hitting soft powdery sand at high speed really speeds up ones heart rate. Only way i see that i could hit the temp cut out would be a really steep hill (actually i mean a mountain) at full throttle. There is nothing like that here so i am done Bottom line, i think it lowered the temps by at least 20deg c. Probably more
Hugh pomeroy - The Hub Sink Is A great invention,It works very well on my Bikes.I took My 7500 watt Fat Bike Up The mountain, Full speed My motor Was Not Warm at all.The Hub Sink Took All The Heat out Of My motor.
Bottom Line Is That It works .
Jesse Haubner - Hubs are making a difference on the fire trails, on a couple hills I used to have to pull over and allow it to cool down, now I get to the top
