    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.

    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...

    30 Days Ago, Needed Oxygen, a Walker, and a Home Health Aid to Leave The House. Today...

    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...

    30 Days Ago, Needed Oxygen, a Walker, and a Home Health Aid to Leave The House. Today...

    Yes, sorry if that wasn't clear! The first segment, I climbed about 1,000 feet total, with 200 feet of descent mixed in. The second segment, I returned exactly the way I'd came, so the numbers were reversed-- a lot of coasting. But returning, I did try to pedal as hard (when I was pedaling...

    30 Days Ago, Needed Oxygen, a Walker, and a Home Health Aid to Leave The House. Today...

    Okay, so I peaked at 109 Average Watts about a week ago; recently, I've been back in the 90s, but my distances and elevation have increased quite a bit. I was doing 3.5 to 4.1 mile rides with 360 to 410 feet of vertical when I first broke 100 watts. Now, I'm doing 7.5 to 9.5 miles with 1,000...

    Do you ride with someone?

    Almost always ride alone, but really enjoy riding with a local colleague & friend when our schedules permit, known him 15 years, always a great time. I do, or did, on two or three occasions ride to some pretty remote spots 10-15 miles from my house alone, places where the first three our four...

    30 Days Ago, Needed Oxygen, a Walker, and a Home Health Aid to Leave The House. Today...

    Up to 87 watts AP on 10/23, but then 92 today, but it's been a weird week-- I also gained a lot of weight, two or three pounds just this week. I have regained roughly 15 pounds, with about five more to go to be back to my previous weight. One thing I did this time was to hit 'finish trip' a...

    30 Days Ago, Needed Oxygen, a Walker, and a Home Health Aid to Leave The House. Today...

    I think Average Watts (Power) is about right given my circumstances. I'm using the metric that is called "Average Power" on the Bosch Flow app, and it's listed in watts. I'm not racing, but yes-- on my fitness rides, I usually never stop and have few low-intensity intervals. The longest are...

    Well, it beats duck tape! That is terrible! I have very mixed feelings about events like these.

    So guys, is "Average Watts" the best single metric for tracking the amount of effort I'm putting into each ride? It seems like it probably is-- this factors in terrain, for example, how much assistance I'm using, but not how long I'm using it, is that right? Ride #4 Post Catastrophe -- shorter...

    Music Junkies?

    Yeah, I know! It's one of those traumatic associations where unrelated events get bonded. When I was on the younger side of four years old-- maybe I was three-- I had a terrible interlude where I became terrified of ceiling fans. It was completely debilitating; in the early '60s, there were...
