After 4,000 miles, they do
not turn as well on pavement as they did with only 500
miles, but they did still steer.
On both tests, the limiter
straps were loose.
When I brought these Triple Point Carbides back to my shop,
after shooting this pavement demo, I set them on my counter carbide down. I
noticed that they rocked sideways. This indicated that the
handlebars were probably in a half turn before the outside carbides
made contact. When I saw these rods at 3,100 miles all three
carbides were the same height. The outside carbides were so sharp I
would not even touch them. I did not look at the carbides before
this demo because the results would be the results. Over the
previous 1,000 miles the thinner outside carbides wore in turns so
they did not touch when going straight, making the dull center
In order to get some more bite back on ice and
pavement I ground the center carbide level with the outside points
with a standard 1”wide Green wheel. Then I bought a ¼” wide Green
wheel (Radiac PN-A016721, 7 x 1/4 x 1-1/4. Price $30.50 at my local industrial supply co.). This let me grind lengthwise the center carbide without
hitting the outside carbides. Because the outside faces of the
outside carbides are approximately perpendicular to the ground they
maintain an edge as they wear. Of course, the bite won’t be as good
as when new but more like a newer 90 degree carbide. As soon as
the handlebars are turned the edges will bite. Because we have as
much carbide below the surface as above you should be able to
maintain the outside edges until the faces wear down to the host
If these rods had been ground
like this, before shooting the video, the sled would have turned
even better than they did!
You can create the best replacement
cycle to fit your riding style and still have some resale value
left on the TP rods for less aggressive riders.
