Hi guys,

I have a BTWIN Rockrider 540 that I am converting to singlespeed. So far, I have the sprocket and spacers ordered and the chain from Amazon. I have two main questions that I hope can be answered. I am a complete beginner at bike engineering so forgive any ignorance that may come across.

Q1. I am aware that because my bike has vertical dropouts, that I'll need a chain tensioner. How can I go about figuring out if this will attach to my bike or not? I took the rear derailleur off and it appears I may need a derailleur hanger to attach a tensioner to, or am I overthinking things?

Q2. Currently, I have the standard 3 piece crank set that came with the bike still attached. I noticed that on the middle cog, there are 32 teeth. Would it be possible to get away with just wrapping the chain around this, instead of having to order a single speed chain ring?

Thanks in advance.
