Road bike conversion
I have an old Bianchi Strada LX road bike that I would like to convert into more of a hybrid. I would like a more upright riding postion, more than 12 gears, bigger tires for light off road riding. The bike currently has Sugino VP Japan 170 crank, Shimano Light Action VIA front derailer, Shimano Light Action VIA rear derailer, Shimano Light Action lower tub shifters, Front Araya 27 1/4" rim and a rear Weinmann 27 1/4" rim. Or should I buy a new bike.

As a general rule older bikes had fewer speed which ment stronger
wheels and enough speeds to accomodate the average rider in
non race rides very well. I much prefer the old 5 & 6 speeds
for in town or short country rides.

I've converted 3 old "race" bikes from the past to city bikes with
new bars, stem, seats, platform pedals and fenders. Had a lot
of fun doing it and all serve me well.

I'm in the middle of such a conversion right now. Changed the stem of my Univega Super Strada to a riser stem- made all the difference. Wish there was a greater ratio spread. Think I'll just deal with it instead of going crazy. The law of diminishing returns kicks in fast when doing projects like this.

"More gears" may not necessarily mean "wider gears" -- and wide gearing, IMO, is more important for anyone on my side of racing/time trialing. One 6-cog cassette would have the same overall gear range as a ten-cog cassette IF the largest and smallest cogs are the same, even though the 10-spd will have more closely-spaced ratios in between. You won't gain a higher top speed or better climbing gear if the smallest and largest cogs are the same; you'll only be missing out on narrow jumps between gears.

You could gain a more upright position pretty easily with a stem with more rise.

There seem to be several tires out there that would fit your wheels and are fatter. As long as they clear the fork & rear triangle, they'd work fine. If there isn't enough room, than that would be a reason to get a different bike.

what crank size and cassete size is good for road bike and mountain bike. Steel road bike 25 pounds aluminum road bike 23 pounds and steel mountain bike 30 pounds. I want go fast on flat bike
trail but i want have low gears too for hills.

I'd say put a triple crank on it, maybe a new rear wheel with a wide range cassette, and tires as big as will fit and leave it at that. the most expensive part of that would be replacing the integrated shifters but if you also went to a flat bar the brakes and shifters wouldn't be that much.

If you have to ask I'd say "Buy yourself a new bike."

Depending on what changes you choose to make, you can easily approach the cost of a brand new bike. In other words, for similar money you can convert cheap old bike into an expensive old bike that has a few new parts which may or may not work together. A new bike, on the other hand, will come with all brand new parts. Every single part will have been designed to work with every other part. It will also come with a new bike warranty.

That's what I'd SAY. You didn't ask what I would DO.

Your Strada LX could be converted to 650b. You could probably fit a 650x38 in that frame. Wider tires are more comfortable. A taller Nitto stem would put the bars up. Perhaps you could change the chainrings to 46 x 34. that would give more usable gears. Some Sugino cranks were drilled and threaded for a third inner ring, see if yours is.
