Hi all. I'm considering starting my first ever bike project. I have a Saracan Backtrax which I bought in 1997. It's been languishing in the back garden for years and through wear and tear and more recently neglect it needs a fair bit doing to it. It's a bike that I loved riding and holds a great deal of sentimental value. From what I can tell it needs a new bottom bracket, rear mech, casette, chain and chain rings. Looking closely at the bottom bracket area I can see it's an SKF bottom bracket. It's my understanding that SKF bottom brackets are extremely expensive and difficult to come by. So, my question is, what bottom bracket could I use in my 1997 Saracan Backtrax as a cheaper replacement? I'm just starting out on this bike project journey and would very comfortably describe myself as a newbie to such things and the terminology. Hopefully, you can help me with your amazing pool of knowledge that I've seen here. Thanks in advance.
