Installation Guide

We're super excited to hear your feedback on the installation and performance of the sinks once you've tested them out, either on facebook or directly at!

Remember the HubSinks work much more effectively with Ferrofluid so ensure yours is still wet and effective or install a new batch.


STEP 1 - Clean the outer magnet ring surface of all dirt and oils before applying the thermal paste or tape, don't use any petroleum based cleaners (WD-40, and many automotive degreasers) The oil, which is engineered to not evaporate, will fill the microscopic valleys in the metal and significantly reduce the effectiveness of any subsequently applied thermal compound.
Keep the surface free of foreign materials and do NOT touch the surface after it has been cleaned. A hair, piece of lint, and even dead skin cells can significantly affect the thermal interface's performance. Oils from you fingers can adversely affect the performance by preventing the micronized silver or ceramic fill from directly contacting the metal surfaces. (Fingerprints can be as thick as 0.005”)

Step 2 – Test fit the HubSinks around the Hub with the included mounting nuts and bolts, there will be a small (0.5mm) gap in the middle of the HubSink arch, when you tighten them down after riding (Step 4) this arch will pull flat and spring load against the hub creating a solid thermal connection, there will also be a gap between the end of each segment (up to 5mm at first) this is designed to (after Step 4) keep the HubSinks pulled tight at all times during thermal expansion and contraction.

Step 3 – Apply the thermal paste generously to the HubSink piece (we want to use the entire 5G tube evenly across the peices) insert the coated piece between spokes and push down firmly, give the piece a slight twist to ensure the thermal paste has coated the entire connection, continue around the hub in the same manner leaving the fixings slightly loose to an equal amount, then go around the hub a few times taking out half the space of each gap per revolution until the pieces are all tightened down evenly.

Step 4 (important)– Turn the amps up and go for a ride, try to get the hub as hot as possible on the first ride to get the thermal paste to seat correctly and efficiently, re-tighten the hub and ensure its all fitted well, repeat this for a few rides and performance will increase as the paste fills al the microscopic gaps and the alloy pulls tight against the hub.

Step 5 – Enjoy & let me know how it goes, any issues etc!
