ONE: Tire Pressure.
This was my third ride on new 27ID wheels and new tires. I had the rear Ralph but slightly smaller. but their big difference was the Racing Ray 2.35 from the previous Nobby Nic, 2.35 (which was on a 30ID rim) I am not a fast rider but I ride some steep trails and this route was very familiar to me. the Ray was not as grippy as the the NN on one section. it was very obvious. Wow, it was fun to experiment.
But on the tire pressure point. I have read that smaller rims will need higher pressures for the same feel. so I increased slightly. yesterday I rode the same trail with 24psi from and 25 rear.. I was was sliding on the loose over hard dirt. but it is a bit moist. so very good overall.
Again I am not a racer (a.k.a. slow) but I can feel the difference.,


TWO: many shades of purple!
I noticed that the two photos I posted above had very different flower colors. I am clueless on flowers. But I am designer, so I know my colors. Today I found out why! Two very different flowers!

I had a great ride. beautiful landscape and challenging climbs. that is all I need. Back in time to make a quick dinner.
