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.
In my opinion I think you would struggle to put anything wider than a 9 speed cassette, and that might be a push, on the rear, your axle won’t have enough space to take a wider cassette and your frame won’t be wide enough to take a larger axle. Given what you say about the weight of your bike as well, I’d be inclined to stick with the 3 x 8 set up and maybe just tinker with the sprocket sizes.
Hi, found this post, and forum after doing a search about changing the BB on the ontero elite. I haven’t don’t the bb as yet but I can confirm you can stick a 1×11 speed on the old thing as you can see in this pic, iirc it’s a sunrace 11-50 cassette and I’m running the shimano deore xt md8000 derailier on a goat tooth extender.
Like you I don’t want need a new bike as this one is doing me just fine, and I enjoy doing the upgrades.
I plan on getting a new frame when this one brakes and swapping the upgrades over
