About this Product
May I introduce HAAFIS & HAARIS two of my best friends at the moment.
You need two right hands and some sense of humor to assemble this correctly. I will not be explaining much more than the below. If you are not sure what this is about then stop reading NOW.
They only fit on the Thunder Tiger SB5 rims. They are bloody expensive. They withstand "normal" use. They will brake in case of a crash. They are NOT for racing
How to: A.)Drill 2mm holes into the rims. 3 x 120° per notch are enough. Later you will fill the inside of the rim notch with CG Glue. I use Loctite 406. B.)The insert rings "clip" onto the SB5 rims. Unluckally the tolerances vary a bit on the rims and on the SLS-Inserts. If the rims fall through (mainly the coloured rims) its not a great deal. Once all comes together and is glued properly it cant misalign anyway. If it does disturb you then look for SB5 rims that fit better. DONT under all circumstances glue the insert to the rim : you will get a wobbly tire in the end :( If the inserts are too small/ rims too big: Heat the inserts (ONLY) in a oven to max. 60°C then they will clip on with ease. C.)You will need Dia.10 Foam (front) and Dia.12(rear) Foam cords. The ones I use have a approx. hardness of 40°Shore. Cut them and glue them to form a ring. "Curlies" will work also. D.)Coat the inside of the tire with baby powder. E.)Wipe the tire tongue surfaces clean. F.)Mount the tires on the Rim/Insert assembly. G.)Use a tool with a rounded tip to force the tire lip into the groove of the rim. H.)Glue the outer lip with CG-Glue. I.)Fill the inside with glue through the holes we drilled at the beginning. J.)Balance the wheelset if required.
You ~can~ reuse the inserts if youre lucky. But its hard to cut all parts apart without ruining the inserts. The inserts withstand Acetone. You can carefully cut off the tire and then put it all together in a Acetone bath over night. The CG will then dissolve. At least one out of two inserts is cracked after all this work. Then its ready to be shelved on the dump.
