    I’m new to the forum and I was hoping to get some advice on my planned upgrade.

    I have a 2008 Mongoose Otero Elite and after 10 years of ownership and never having been serviced, it’s time for some replacement parts!

    Firstly, I know that a lot of people will say save your money for a new bike but I’m happy with 80% of my bike and it’s just the wear and tear that needs attention. I don’t have the money to shell out thousands on a new bike and I like to save money by doing my own mechanical work.

    The bike was cheap but it has a strong (and heavy) frame. I have upgraded the fork, brakes, pedals, grips and added a dropper post. Now the gears are worn out and need to be replaced. Instead of replacing like for like I thought it would be a good time to upgrade.

    It’s currently an 8×3 set up and I’d like to upgrade to a single chainring with a 10 or 11 speed cassette. Is that possible? There’s a lot of kit out there and it’s difficult to know what’s compatible with what. Currently I need to replace the bottom bracket, crank/front chainrings, rear cassette, rear derailleur and free hub. I’ve priced it up and it looks like I could do the lot as like for like for around £150. As I’m doing the work myself I’m happy to increase my budget to £200+ for the upgrade.

    The bike currently has Shimano Alivio RD-M410 rear derailleur, CS-HG30-8I cassette, FC-M311 22/32/42 crankset and Alex TD-24, 32-hole wheels.

    I’m not in any way an extreme mountain biker so I’m looking at the budget end of the component market.

    I’d be grateful for any suggestions.
