Advice for Newbie?
 

I refurbished my old CrMo road bike and it rides great. However, before I take off for a nice, long ride I would like a little advice. I now weigh about 230lbs and would like to know if there are any modifications that I should make. (i.e.tire pressure, wheels, or anything)
I'm going to replace the Weinmann 27" wheels. Should I get what I want? Or is my weight a factor?
Thanks.

crushingmetal, If the bike is working fine don't 'fix' anything 'till it's broke. Your weight isn't any real threat to the wheels if they're in reasonable condition (running true). Some 27" rims don't have a bead retainer, usually older steel ones and tire pressure should be kept at 80 PSI or slightly less. Look for a lip on the inside opposite the braking surface, if present you can go above 80 PSI. If you have steel rims now consider replacing with aluminum 27" rims with a wet weather braking improvement the most benefit, secondly there'll be a reduction in rotating weight. I used 27X 1 1/4 tires on aluminum Weinmann rims at usually 80-95 PSI on my old Raleigh when I was above 200 lbs.

Thanks, Brad. That's the answer i was looking for. Just wanted to be sure before i got too far down the road

Your weight is a bit of a factor, but not as much as you think. As for the wheels, check to see if your brakes can be lowered the 4mm needed for 700C, if it can that opens up a lot of opportunities. In the 1970's some manufacturers were using 27" in some countries and 700C in others, eventually the 27" were used fewer and fewer places, and now the only 27" wheels to be found are replacement parts. The opportunities are in tires, you go from a couple of decent tires and a couple of crappy ones, to the whole range of tire widths and types. Your best to go with a 36 spoke wheel, not because you need it, due to weight, but it looks better given the age of the bicycle.
