Postby eddo » Mon Jul 06, 2009 4:11 pm

I currently have a avanti mtb, 24 speed (11-30 and 24,34,42) and 26x1.5 rims with 1.1 slicks.
what can i do to improve on this gearing. I only use it on the road now.

Hi Eddo,

What's the problem with your gearing?

(too high? or too low? or just worn out?)

Sorry, but your initial post doesn't give much for people to help you with.

OK, I'm guessing here, but you want more usable ratios?

Swap the 11-30 for a 11-25. Easiest change. You'll notice yourself being able to choose the 'right' gear instead of spinning out too fast or mashing too slow.

If you're wanting taller gearing, you could put a 44T or 46T big ring on next time you replace the chainrings. Given that your granny is 24T, you should be able to get away with 46T with most front derailleurs

Alternatively, you could try 700c wheels with 23/25mm slicks. They will still fit your frame and forks. This is what I have on my mtb commuter, I've seen a local guy do the same on his Yeti 575, and Kalgrm has done the same on his dual-susser.

This really is only effective on bikes with disc brakes. Given he has a 24 speed bike, it's most likely to be an older bike with rim brakes.

Mmmm... I had a Mongoose 24spd wth discs, and there are plenty of similar bikes around to be bought new, but yes, if he has rim brakes then 700c is off the menu.

Okay, fair point. I'll qualify my statement to say to the OP: "if you don't have disc brakes, don't consider getting 700c wheels."

Cheers,
