I didn't see and braking bumps, but I did see a lot of locking up of rear tire marks. Did you ever have one of those days when everything went right for a change? I went out this morning looking to do 2 laps and then trim weeds for awhile. 1st lap, I had a lot of noise from the rear wheel. sounded like when your magnet hits the sensor on the front wheel. finished the loop and got to my car and found the cassette loose. I tightened it and did another loop and for some reason everything felt great so I kept going. I got in 4 laps all under 42 minutes each. the best 37. No knee pain. very cool. now to lose 20 lbs after being hurt for a year. The trail was perfect.
