Mtn Bike Rentals near San Diego, CA

[timhines]

I'm going to be in SD for a week. Could someone suggest a good place to rent some Mtn Bikes (low end is fine)?

I'm sure wherever we rent from can advise us on some local trails.

Thanks in advance for the info.

What area are you going to?

I will be a few blocks from the convention center, basically between the convention center and the airport.
