    These are great resources and I will look into them! What I'm wondering now is if WALKING in my neighborhood qualifies as Zone 2. For the hills at least, yes, I can speak in complete sentences, but my speech would reflect the fact that I'm exercising. Given the topography of where I live...

    Actually, I do not have a cardiologist, though my GP consults with one regarding my case. I meet with my GP in a couple of weeks, and I'll ask her what HR she might recommend or if she has any thoughts on the situation. She may either give me numbers to hit for each zone, or refer me to...

    All this means I should probably wear a heart monitor, which I loathe doing or even thinking about. Are there any that are completely offline that anyone would recommend? Thanks! I'll ask my doc r.e. FTP test.

    Exactly! (Sorry, Endi and Harry, Stomp is referencing a separate dialogue from another thread.) Yeah, would love to see a picture, Harry, thanks for checking the PDFs. Sorry to be extra-cautious!

    diy light weight ebike

    I do not think anyone should download an unknown .PDF off this or any other website. I would be interested in the specs, but this may not be that appealing to most folks, given that commercial eBikes are available with very good specs in that weight range, though they are mid-drives. I own a...

    130 watts on the 4.1 mile loop. This ties my second-highest-power ride for this loop ever. I only have one ride pre-aneurysm that beat this, at 133 watts, and I only have on ride which beat this for fastest time, which was POST aneurysm. For sprint speed, I am obviously back at full power--...

    New ebike laws in California taking effect January 1, 2026

    I agree with Speedub that this is not a huge change, but the tinted windows are irritating here in Hollywood in terms of threat assessment, on a bike, walking the dogs, etc. I like to know who is driving around up here. I like to be able to see if someone makes eye contact and gives me a...

    New ebike laws in California taking effect January 1, 2026

    Yes! And the geniuses in Stuttgart make their bikes so safe they will kill us all! (Stefan and I love poking fun at German engineering, though I think we both genuinely admire and respect their work.) Bosch's "Flow" app has a huge warning that explodes across your phone screen after you boot...

    Gravel Vs. Trail Bikes

    I found your batteries delivered more than 2.5 hours-- I figured the range at around 32 miles, and at average speeds of about 9 MPH, that netted out to around 3.5 hours... and that was assuming about 2,500 to 3,000 feet of vertical. I could imagine getting four hours on more sensible terrain...

    Gravel Vs. Trail Bikes

    I do not know much about the technical specifications of gravel bikes for racing or competition. My only experience is the Canyon Grizl: ON used for purely recreational purposes on road surfaces, bad pavement with lots of cracks, severely eroded asphalt that is like 'gravel' in that there is a...

    Brake Wear Question -- Is it possible...

    It sounded fine the last two rides. I wonder if there was some grit on the pads that just burned itself off. It has only been ridden in drizzle once, and I did wash/wipe it off, but there's plenty of sand and debris on the road. It sounds like none of this involves any brake bleeding, so I'll...

    Brake Wear Question -- Is it possible...

    This is very helpful. I need to do a deeper dive into YT diy videos for checking the pads. The disc is not warped, at least that I can see. There is no wobble at all. Brake drag is possible. Better brake pads sounds like a really good idea. Super helpful!

    Brake Wear Question -- Is it possible...

    ...that I could have burned through the pads on my Canyon Grizl:ON 7 in only 250 miles?! I live in an area with a lot of steep hills, yes. But this seems like an absurdly short service life. My eMTB's brake pads were good for at least 500 miles in this terrain, and it's 47 pounds as compared...

    Beware Having REI Set Up Your Canyon - Potentially Dangerous Fail

    Good point. Safety Cycle is probably unique in this respect. I think the manager is looking over everyone's shoulder. (And they do charge a bit more.) Not yet, but I think I'll give the shop a firm but friendly call.

    2025 - Our Rides in Words, Photos, Maps and Videos

    First photo is looking northeast from behind the Hollywood sign, the second looking southhwest. An unseasonably, unreasonably warm southern winter twilight when I realized I was further from home-- less than four miles, but I climbed over 1,000 feet-- than I'd been been since I got out of the...

    Beware Having REI Set Up Your Canyon - Potentially Dangerous Fail

    Perhaps. My criticism said 'beware' not 'do not have REI set up your bike. It's also fair to note that this was REI Burbank-- I'm not sure other stores would have the same issue. I really, really wanted to like their work, as I love the concept of the store, the fact that they lead tours...

    Beware Having REI Set Up Your Canyon - Potentially Dangerous Fail

    So, a few days ago, I'm doing my usual four-mile fitness loop, and I go over a crack in the sidewalk I literally have gone over two or three times a week since I bought the bike this spring. I hear a sharp click as I feel the bike seat tilt backwards a notch. Then I kind of relax. No big...

    This is great advice-- and theoretically, it should work with the REST of my recovery, the process of reassembling my personal and professional life, which is going very well, but January and February, I'll have a lot of work to do. For intervals, I think hills are the best, even if they are...

    115 Average Watts on the 4.1 mile loop, beat my post-ICU record by a full 6 watts. I'm also within 20 seconds of my fastest time for this run (though for that ride in June, I put out 130.) @stompandgo was right. All the capacity is still there. I can do this-- meet or beat my previous...

    Introduction

    Welcome to the forum! (And welcome Ava.) My main bike (my fourth) is a Canyon Grizl: ON CF 7, a 55nm gravel bike, though I also have a 40nm Motobecane Ultra eMTB). I've also had two conversions that failed, one a Marin with a TSDZ2B which cracked-- hey, it was an experimental build, we knew...
