Finally got around to doing the A services on my R500 and E430. After that went mountain biking. ~7 miles on a trail I’ve never done before, approximately half of which was awesome, the other half being not single track or grinding uphill stuff. Super fun. For about a mile of that my buddy and I switched bikes.
I have an old trek 3700 with 26" tires, terrible maintenance history, hard tail, crap front shock, slippery pedals, poor gearing, v-brakes and narrow bars. He has a Santa Cruz blur, with excellent maintenance history, excellent gearing, wide bars, shin killing pedals, hydraulic disc brakes and suspension from a coupe de Ville with a 3" lift. Almost killed myself the first time I pulled on his front brake. But damn that was an awesome and confidence inspiring bike to ride once I got used to it.
