Are there any steel frame and fork bikes with a 2x crank and 650b tires? Sub $2,000.
I decided I can't ride a vintage frame anymore on account of the reach. I need a bike that's easier on my post-surgical back. I'd like to get a 650b bike for a comfy ride, and for toe clearance. It looks like all the manufacturers have decided that 650b bikes should be 1x…

What Travellers Say
Reviews Summary
Visitors praise Big Rock Trailhead for its stunning panoramic views and the beautiful wildflower displays in winter and spring. It's a great escape from crowds, offering a challenging hike or bike ride. However, the lack of shade and potential for strong winds are notable drawbacks, and caution is advised around wildlife.
"We took our bikes up the mountain for a quick ride around the loop and it offered plenty of challenge. A steady climb the whole way up gave way to stunning 360 views. Be careful of the cows (one seemed ready to charge) and a dangerous dip on the back side made me fly from my bike. Gorgeous scenery on paths not very traveled, great escape from the usual bay area crowds."

"Scenic hike to the top. A decent amount of elevation gain. Enough to get your heart beating a bit! Beautiful views of the hills and a glimpse at SF from afar."
Kyle
"This trail is a decent hike from top to bottom. Biggest draw back is no shade for majority of trail. Would be awesome winter/spring trail. Nice views of the bay at the top as you can see everything around."
