Firenze BB upgrade
 

Hello everyone. This is my first post so take it easy on me.

I recently bought a Firenze GL5000 at a rummage in decent shape as a fixer upper as I am not sure how much I want to spend on a good bike until I know how much I will use it.

I was looking at replacing the cranks which are the older cottered type. I am assuming to replace the cranks I would most likely need to replace the BB as well.

So my question is, Can I convert it over to a new modern style bottom bracket? and if so how would I find out what size I would need?

Thanks in advance for any help. I am totally new to biking.

You would need a new BB to use modern cranks. However, I would not recommend it. Firenze bikes were given away with home appliances. They were not allowed to be sold due to not meeting US specifications. Contrary to the name, Firenze was made in Taiwan. Overhaul the BB and replace anything that needs replacing then just ride it. Upgrade to a better bike when you want to but don't sink too much into this.

I agree with melonbar - don't spend a lit of money on it. I you are not familiar with bike maintenance, use it as a learning platform (the bike will ride and work better once it has been serviced) and keep an eye out at other sales and Craigslist for a better bike.
