got the bike repaired and upgraded. with Shimano Deore 4 piston with cooling fins and cooling rotors. the mechanic got the front disc rub free. went for a test ride down a 20% grade 5 blocks from the shop and I could stop completely with one or two fingers. this is great such a huge improvement. We had taken the bike in for a quote and then picked it up later in the day and it did not look like they got a quote so when we took it in after the crash I found out they had already ordered the parts. the= guy who's dog caused the crash said he would gladly pay for the repair so that was 150 off the 550 bill.
