I currently have an inexpensive 24-speed hybrid that needs a new crank and front derailleur. I am thinking about replacing the three-speed crank with a one speed crank and removing the derailleur and shifter making the bike an eight speed bike. This brings up two questions.
1. What crank do you recommend? I would like to put on a 36 or 38 tooth crank but I do not want to sink a lot of money into an inexpensive bike.
2. Are there any "gotchas" that I need to worry about. Can I simply replace the crank and remove the derailleur and shifter or is there something else I need to do?
