BT56 -vs- BT57
So a few of months ago I'm in Cycle Gear, looking over the discounted stuff. Returns, custom orders never picked up, etc.
The longer the stuff sits, the bigger percent they mark it down.
I saw a new Bridgstone BT57, asked about it, and was told it was ordered but never picked up.
Didn't need a tire, but figured I'd come back in a month when the price dropped again and see if it was still there.
I did, it was, I bought it.
By my math it was $30, but by some fancy math performed by Cycle Gear register it ended up being $25!
So, on to my question: What is the difference between my stock BT56 rear tire, and this BT57 (other than a being new)?
Is it a softer compound?
A harder compound?
Will I notice any difference at all?
