Reading over various discussions, I haven't seen anyone mention one advantage of a 17" wheel over an 18" that I think is very important..

Not sure how to explain it, but here goes.

(Regardless of the brakes you are using), the 17" gives you a braking advantage over the 18".

On the 18" wheel you are stopping a wheel from turning that has a 9" radius.

On the 17" wheel you are stopping a wheel from turning that has a 8 1/2" radius.

That 1/2' doesn't seem like much, but that 1/2" reduction means your brakes are applying more force to stop the bike because less is required to stop the wheel from turning..

Can some of you math wizards explain my theory better than I?

NOTE: On my bike, I choose to build inner and outer brackets for the caliper's (as I feel 2 brackets are more rigid than just 1 bracket.

Because of the extra parts, I was concerned with Un-sprung weight.

So, I measured the weight of the 4 pot Tokico caliper's, 4 (aluminum) Brackets, and bolts that I used, and compared

that weight with the stock set up (which uses steel brackets).

I think I recall that the weight of the 4 pots (and hardware) were less than a stock set up.
