FBC Hex Carbide Tire Studs

These studs are the best bang for your buck!

These hex studs gripped better most others studs I have tried. They made me feel a lot more confident on icy trails, also I was having a lot more fun while the others I was riding with were losing traction with their studs. I have them in my terrene yippee ki yay tires and they are great together.

These studs are insane. They do not seem much when one looks online but comparing them to a Terrene Triple Carbide they are almost 1.5 times the size.
They inserted as easily as any decent aluminium based stud, I use a "about to go the recycling" milk bottle cap filled with isopropyl alcohol as my stud 'lube' dipper.
The t-shaped tool is a big improvement on my first experience screw driver style tool.
The studs seated well, I roll the wheel and do a second press of each stud with the tool, just to be sure.
Conditions did not allow me to perform the recommended "10-15 km of asphalt" riding as everything was already covered in snow and ice here so I did a mellow, low torque, not much climbing, 20 km ride on a packed and groomed snowy trail. I did not lose any studs and none were loose so it seems to have done the job.
The second ride was into our local single track and starts with some serious 15º climbs. Other than pfaffing with pressures (new style tyres in addition to new studs) there were no issues and I could hear and feel the incredible bite that these studs impart to the trail.

Hard packed snow - no issue; frozen snow - no issue; glassy water ice - no issue.

I suspect that I will not possess the personal bravery to find the limit of lean and grip on these studs. I can throw the tyre into a side knob lean with complete conviction that the studs will help the tyre achieve and maintain velcro like levels of grip. If you have the power, balance and the gearing to pedal up it the studs will grip on it!!

I am now at 150 km on these tyres/ studs and other than damaging two rear studs on a rock, they are all remaining in their pockets and they seem impervious to trail debris like roots and rocks.

Sure they are noisy on tarmac or concrete (like a helicopter turbine at idle) and they definitely have more rolling resistance and suck more energy than the standard carbide stud but one cannot have everything and I will take grip over a bruised (or broken) hip any day of the week.
If you live somewhere with mixed conditions, with a lot of clean tarmac time, then perhaps these are a little over the top but for a bike that is dedicated to snowy trail riding, or you live somewhere where almost everything is snow and ice covered for five months of the year then these are the studs to trust without question.

Good quality and a good price and great customer service from fatbikes.ca.

These are incredible, like velcro for icy trails. My first order was short a pack of studs, but FBC was quick to fix it and sent the missing pack immediately.

Easy to install with the tool and some rubbing alcohol in a spray bottle.

I've had a few studs pull out on roots sticking out of the snow. I don't think these specific studs are to blame since the base is pretty much identical to previous worn-out studs. It's likely that the stud holes were a bit worn out after removing the old ones.

My advice is to use rubbing alcohol to remove your old studs and minimize damage to the rubber. Buy a few extra studs, and replace them as needed with a spot of vulcanising cement.

I replaced the 2 centre rows of original studs in 2 sets of Dillinger 5 tires with these after the 45NRTH ones had worn flat. They are a little taller and more aggressive and I think they give better traction on ice than the originals. The originals lasted for 5 seasons and time will tell if these do as well. I used a spray bottle of soapy water to lube the sockets and they popped in just fine, took about an hour per tire to remove the old ones, and insert the new ones. When I eventually replace the tires I think I will buy unstudded and put these in the two centre rows and 45NRTH XL's or Terrene triple traction studs in the outside rows.
