Silly question but I’m in a debate with a friend on which side of Twin Peaks is which and I can’t find any answers on the World Wide Web.

I’ve always thought the South side is the frontside of twin peaks and the North side is the backside and my amigo thinks the opposite.

I’m prepared to be wrong but I don’t think I am. Am I?

I am a road rider and have no off road experience. I grew up in the east bay and am very familiar with the Wildcat/Tilden fire roads from walking them, so I know what that terrain is like - lots of ruts. 

I am interested in getting a gravel bike to ride on those fire roads/double track, but I have no idea how wide a tire and what kind of bike setup I need. At first I was imagining something like a Kona Libre, but now I am wondering if I should get a bike that can accommodate 50mm+ tires to deal with the terrain, more like a Salsa Cutthroat. Or should I just go all the way and get a MTB? I wasn’t planning to get a MTB and ride single track, I was imagining riding out my door and doing long-ish rides on the fire roads. My inner roadie fears getting something too heavy and slow. What are you all riding out here?

Hi all! I'm planning a multi-day bike trip for me and my friends. Please see below for the trip:

Day 1 - Berryessa BART to New Brighton State Park

https://ridewithgps.com/routes/48951960

Day 2 - New Brighton State Park to Castle Rock State Park

https://ridewithgps.com/routes/48951819

Day 3 - Castle Rock State Park to Berryessa BART

https://ridewithgps.com/routes/48951889

Have any of you done a similar trip? Let me know if you have any advice for these routes. I'm trying to stick to paved roads as much as possible, since most of us will be on road bikes with 25mm tires.

Also, please send any food, drink or sightseeing recommendations along the route! Thank you!

A friend and I are planning to do the shoreline hwy loop on sunday but found out the GG bridge is closed to bikes until 10:30 bc of a running event. Any recommendations on where to park on the north side of the bridge while we do the ride? I've always biked from SF so I'm new to the park and ride situation.

Avid cyclist visiting SF on Sunday and Monday! Was planning to do Alpine Dam/Mt. Tam on Sunday and something like Diablo or Old La Honda/Tunitas on Monday. Anybody out there as well? Any group rides, insider tips or road closures I should be aware of? Thanks and stay safe

Is there a good bike route up to the top of Mission Peak, or as close as you can get to the top by bike?

The main hiking route from the Stanford Ave parking lot is super steep, and I don't think I can manage it on my gravel bike. Hoping there might be a less-steep-but-longer route up to the top.

If not: what's your favorite sunrise bike ride in the Mission Peak area?

I ride in the early morning for ~2 hours and my feet go numb 5 minutes in... I have some pearl izumi toe covers that are better than nothing, but don't do much. it's usually 30-40 degrees at the time I'm out on the road.

any recommendations other than pearl izumi?

I live in South Bay, where I have easy access to the santa cruz mountains, as well as the diablo range (mt hamilton area.) There is so much in the santa cruz mountains, since it's been inhabited for a long time.

What do you think is the best area specifically in the bay for riding? I'm talking about mountains and scenery.

This sub recently gave me advice on finding some old rims for a non-bike related DIY project. I’ve got my rims and painstakingly removed the spokes by unscrewing each one. Would anyone like these old spokes, or is there any use for them other than throwing them in the trash? Would love to keep them out of the landfill if anyone could use them. The rims are approx 20.5” in diameter. Cheers!

I rode in Portola Valley this morning and there was a lot of road work on Arastradero and Portola/Sand Hill Road, including three one-way sections with flaggers.

I think I'll try to avoid that route until they're done, but I can't find any info about that road work online (including 511.org and Google Maps). Anyone know where I can check on its status?

I just rode on Spruce and it was being repaved. I didn't think it was in too bad shape to begin with. I wish a few other roads got repaved instead - like Tunnel! Anyway, be aware it had a lot of loose gravel so be careful on what is usually a fast descent.

Hey friends!

Registration for RIDE 4 A REASON (https://www.r4rschools.org/) is open! It's a fun (not a race!) century ride on Saturday April 26 2025, from Oakland to Sacramento that raises money for local schools. 😍

It's truly a beautiful day out on the bike -- there's kids, teachers, families and everyone in between. I did R4R for the first time in 2016, and it's what got me into endurance cycling, and eventually, triathlon and other bonkers adventures. (There are shorter options if you don't want to do the full century, and a return bus fare is included in your reg fee. Or you can do what many of my friends do, which is take the train back.)

Join me on the ride and use this referral code: 🚴

I have recently started dabbling with chain waxing and am happy with it so far. I have heard varying things about how well it works in the winter, with some people saying you need to re-do the whole waxing if the chain gets at all wet and others saying it isn't any higher maintenance than regular lube.

Do any of you wax year round here in the bay area? What has your experience been? Trying to decide if I should switch to wet lube for the rainy season

I’ve been working on an app called Pointz that’s all about helping riders find safer, low-stress routes to feel confident and comfy on the roads. Right now, it has emergency roadside assistance, plus a color-coded road safety map (from red to dark green for safety ratings), a slider to help choose the optimal balance of safety vs. speed, and options for specific preferences, like avoiding hills, selecting routes for different bike types, avoiding multi-use paths, and more. It has a bunch of other things like a way to record your ride (like Strava), GPX exporting, and even crowdsourcing (like Waze).But I'm curious—what features would you all actually use? Especially folks who are new/intermediate to riding in cities and suburbs. Would love to hear your thoughts 

Planning on doing Mt Tam climb this weekend. On weather.com saying low 50-60s. Obviously with so many microclimates I never trust the weather websites.

Will start around 7 am and hope to get to peak by 830 on Old Railroad.

Planning to wear long bib, light thermal jersey with short sleeve base layer.

Do I add a jacket or vest to this? I usually run on the warmer side but my core does get cold on rides.

Thanks!

I saw some signs there the other day but didn't stop to read them. And now I can't find any information online. Anybody have the details?

Google maps keeps pushing me to use Grand/Gateway, but is it possible to get to Poletti from the station and from there to OPB?
