The Famous Blackbone 2 Speed System for the HPI BAJA!
Order the correct gears (2 sets ideally 2 ratios apart, ie 19/55 and 21/53)
The kit contains:
- HD steel clutch bell (15mm shaft diameter) (NEW V2 DESIGN)
- HD 2 speed custom layshaft with one way bearing system
- 2 speed Alloy Spur gear carrier
- Get the best of both worlds for your Baja, Groud breaking launch and hit second gear for that top end speed you are looking for. Don't choose between torque or speed. Get both with this BBRC two speed.
-
Gears are available via separate listing, this is just for the 2 speed system.
IMPORTANT GEARING ADVICE:
- Don’t set the difference between first and second too great or you’ll notice smaller engines will struggle to pull second gear. a Maximum of 4 pinion teeth for the jump, eg 18/56 and 24/50 will be rubbish and no point buying this system for bad performance
- For most tuned zenoah style engines, start with 18,19 or 20 for 1st gear and go for 20, 21 or 22 for second gear, youll get the potential from the engine and the transmission this way.
- My advice on 24/50 is that only really for 40s or twins. 23/51 is plenty for second gear on even a very powerful 34cc.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?:
I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them.
The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.

Fantastic. I put lotion on my feet & wear them when I go to sleep. I often wake up during the night and will remove them to find my feet soft and smooth. They are strong and fit my size 10 womens’ size.

Great product to keep moisture in
Size: M (up to size 9)-Beige
These are so cool. I was skeptical at first. After an at home pedicure I put lotion on and keep these on for about a few hours. The moisture retention, and comfort and fit or absolutely amazing!
