I bought a 1984 Miyata NineTwelve. Stripped her down to just the frame/fork,headset,stem,seatpost and put on
Shimano 105: shifters, rear derailleur, crankset. (8 speed)
Shimano 600 FD, Ultegra Dual-pivot brake calipers and Ultegra Cassette (probably 2 years old at this point)
Crankbro's Eggbeater pedals
Mavic xp 22 rear wheel (old and beat up as heck) and Alex (generic front) (both 32 hole)
Michelin Lithion tires
REI RX saddle (not that impressed)
every time i rode on my girlfriend's 92 Allez with thin wall tubing i've been mad jealous about her ride quality. I thought my miyata would be comparable. I learned something yesterday I wish I would have realized a year ago. Having crappy old wheels is not the way to enjoy a great steel bicycle.
I bought a new Mavic Aksium wheelset. My miyata was reborn from the ashes.
So on to my question. What next? I'm thinking a new cassette is in order. Is it worth my time and money to upgrade stem/seatpost to carbon? Any recommendations for an awesome saddle ? (i know we all have different preferences. I'm looking for something that will be conscious of sensitive arteries and comfortable for 100+ mile rides)
