I got the '78 PR10 out for a 36 mile club ride today in the citrus groves of Ventura County. It held it's own with the modern carbon bikes. I recently replaced the broken Simplex RD with another from French Ebay. Also changed to a new 8 speed Sram chain. Rides and shifts smooth now. It's a great bike. It's been posted before, but here's a new picture.
