    Gummee, how wide is too wide for cyclocross rims? I'm looking at mtb wheelsets for a second pair of wheels.

    Around 22/23mm internal would be my personnal max.
    My last MTB had 2.25 tires on 18mm (internal) rims and the new one has 2.3 maxxis on 22mm rims.
    Don’t see the need to go wider than 20mm for anything smaller than 2inch

    My American Classic TCX are 22mm internal, and my HED Belgium+ are about the same. I typically run 35c tires on them but wouldn't hesitate to mount them on a rim up to about 26mm internal. Those HED rims have had 700x23 tires mounted up tubeless, and they measure out to about 27mm once mounted.

    Well I had an early meeting up in Waynesboro yesterday and the rest of the day off, so HELL YEAH take the road bike and do a ride on the Blue Ridge Parkway! The weather forecast was for fog in the low-lands but clearing by early morning, calm winds, then ample sunshine later in the morning. Fooking liars - it was 36*F and dense fog with a STRONG westerly breeze when I got up to the start at around 9:30 AM. I couldn't very well wear my cycling bibs, clomp-clomp road shoes, and jersey to the meeting so I ended up standing nekkid next to the car in a secluded pull-out on the BRP changing from street clothes to riding gear. Damned near froze Mr. Winky right off but I don't think I've ever geared up so fast... Finally got all dressed in bibs, insulated bib tights, long-sleeve light-weight jersey, light breathable cycling jacket, helmet liner, long gloves, and glow-in-the-dark yellow-green wind vest. I knew I'd be generating some heat climbing those long BRP grades and staying dry is always the crux in cold weather cycling so I took a handlebar bag with extra dry gloves and room for the cold gear once I started shedding it as I warmed up. The bike was festooned with blinky lights for the fog, front and rear - ya just never know, even on the BRP.

    So, off we go! Obligatory BRP Mile Zero sign photo:

    It was gorgeous but the combination of 100% humidity and steep, long hills was making it very difficult to stay dry... I tried to keep my pace down and not sweat but it proved impossible and I was drenched after four or five miles, in spite of losing my out layers. That was fine while climbing but even the shortest downhill and higher speed made things VERY cold. I finally got above the fog after about seven miles and it felt GLORIOUS:

    [​IMG]

    At Raven's Roost Overlook I took the time to snap a few shots; it was incredibly beautiful and the photos don't do it justice at all. Looking Southwest toward the upper end of the Shenandoah Valley and Blue Ridge Mountains, with the Allegheny Mountains off to the West:

    [​IMG]

    Looking Northwest, there should be a big valley down there:

    [​IMG]

    You can see I was just barely above the fog and there were still a lot of clouds that kept the sun obscured most of the time. I was pretty soggy in spite of my efforts to stay dry, it wasn't warming up much that I could tell, the wind was still blowing, and I was starting to get concerned about getting too cold on the long descents back to the car. I rode on to Humpback Rocks at MM13 and decided to turn around rather than keep riding and risk hypothermia. I've been hypothermic three times in my life (twice in August!) and have zero interest in doing it again. So I did a slow ride back, into the wind and downhill = COLD :vardy but managed it well enough to survive. Of course the sun broke out in full force right as I got back to the start:

    [​IMG]

    I loaded the car, changed out of my soggy gear, and drove back toward home on the Parkway. The temperature had sky-rocketed to 43*F by this time too. Here's the view from Raven's Roost after the fog lifted:

    [​IMG]

    All in all it was a fun ride and just amazingly gorgeous but I think I'd be better advised to stick to flatter ground when it's that cold and humid, it's just impossible to stay dry when climbing those long hills no matter how easy you take it. Maybe I'll start later in the day next time too, if possible.

    Depends on whether you're racing a UCI race or not.

    UCI = 33mm and they check. Too wide and you're DQed

    Anything else? Run whatcha brung

    I caught a case of the fuck-its this AM. No ride 'cause 'fuck it.' Legs are still tired from Sun. Did I mention the crash in the sand pit in front of me? No? Well, Eric got his wheel chopped (so he said) in the sand and went down. Everyone behind him got delayed. :bluduh Did I mention I hit my max HR at the top of the hill every lap? Yup. :nod 152 BPM at the top of that #$%$ Just about felt like puking every time I turned left and headed back down the #$%#$ hill. :nod

    I harked up one of my lungs at the top of the hill in my one and only ever mountain bike race years ago. I won my class but at what cost? Lesson learned. :D

    Reading comprehension are hard :dunno

    Can't answer the question 'cause its irrelevant to me: tubulars FTW

    I've got some Zipps (wider), some Shimanos and Mavics (narrower) and some 'brand X' carbon tubulars that are the same as the Mavics and Shimanos.

    :ricky

    Carbon tubulars are the tits till you hit a root just wrong and crack your front 303 tubular. AMHIK how *that* sounds!

    Doc reckons my old ticker is in good shape and younger than my 68 years. Weight is stable at 67kg +/-1kg - I have to watch that and keep up with the kJ burnt on the bikes. RHR... 55-62, lower when sleeping. BP of 120/79 measured weekly (more often than needed) at home... healthy for a fellow in his 20's so I'm not exactly high risk for a heart attack regardless of how hard I push myself. I was given a Garmin Chronos which records HR all day, every day and that also goes into my calendar.
    Max HR v age is just a guide and some people have a higher maximum, some lower. My max HR last week was 172, absolute max is 176-178 (put's me on par with a 40 something yo), but that's just too much pain and normally working maximum is in the 150's up to about 165. Let down by legs and recovery time, diet and supplements help, and avoid doing more harm than good so 135-142 is my target range with only brief periods at higher rates - I'm only looking to maintain a certain level of fitness with cycling without beating myself up and coughing up a lung isn't on my todo list.



    A little arthritis seems to be a fact of life and there's some stainless steel which causes some aches - I call it wear and tear... best method to combat it is regular exercise. There's some medication involved, but it has been substantially reduced. Free weights a couple of times per week to maintain the upper body. Occasionally I'll swim a 20min session - have to be in the right mood for that though. I absolutely will not run and I don't have much love for walking/hiking. Enjoy off-road moto touring (spent a lot on my bikes for that) and get away a few times per year... and there's no need to make getting away more work than it needs to be by hiking or cycling.

    514km since Saturday. Two road rides totalling 163km over the weekend, a fairly easy 26km of gravel in light rain this morning. Two commutes totalling 325km with eAssist (don't want to do that on human power alone) so is recorded as 8.5hrs at an average a hair under 200W in a profile similar to the trainer. For all intents I treat the commutes as trainer sessions, except that they are not... being out on the road is far more active than sitting on a stationary trainer so it gets its own profile.
    I've been getting more than enough road time (over winter I reduced the weekly commutes from three to two and it is a comfortable level) so it has been months since I've been on the trainer. I've got three trainer sessions with the club's coach over the next three weeks to measure some performance metrics including ECG and VO2 - he's responsible btw and won't do the latter without the former, plus it is something I can dazzle my GP with during annual check-ups... he likes to be dazzled! The last session was back in May and there has been a noticeable performance improvement since then. GC has bumped my CP and FTP by about 40W, but those are software estimates. The sessions in a controlled environment will give more accurate numbers. I was actually quite happy with the numbers back in May, improvements are nice, but I would have been happy to maintain the status quo.

    I don't plan to live to one hundred, but I do want to be able to live whatever time I have remaining. Whoever came up with the notion of arriving at the grave broken and beaten was a fool who failed to consider that there is probably going to be a good few years of nursing care for that pained, broken, overweight, immobile and failing body before it finally succumbs to a slow death. I want to be able to continue until I drop.

    Not much I can do about the weathered old mug without spending a tonne of money to come out looking like a Barbie family member. I'm not so vain anyway and it doesn't seem to hurt with the younger lady who's a fit and beautiful 38 (and shames many teens) and doesn't mind a few years on her fella if he's looking after himself.

    I’ve taken up walking. It’s the only thing my body will currently tolerate.

    Getting there on rebuilding my old frameset. All I need now is a braze on front mech and a couple of bottle cages.

    Yeah, no tubulars for me. There's really only one race/year where they'll measure tires, so I don't know that I care that much. But I do want to figure out how much internal width is too much when it comes to a standard cyclocross clincher. I'm thinking up to 23mm internal should be OK.

    I have a pair of 33mm (CX3s) tires mounted tubeless to a pair of DT Swiss M1700 wheels. Seem OK to me. :dunno

    Tubulars are the bee's knees for gravel and CX. ...but its amazing how many people look at me like I have a hand growing out of my forehead when I say that. Mostly from the guys that don't race CX.

    Aaah well. It'll be my secret

    This one is a more in depth comparison and directly talks about the GCN video.
