First metric century today! A little bit rainy, but mid 60s was a great temp. A buddy did the ride with me hungover so we took a chill pace, especially in the headwinds, and it made for a fun ride. We went out a took a loop around a local lake before going further out to the next town and then back home. People looking at you like you're crazy showing up at a gas station in the middle of nowhere on a bike is always fun. They had loving bomb homemade apple fritters. A+, would bike again.

Unless you have have reason to suspect it's outside of normal, those numbers in isolation are not alarming. I know 50 year olds who hit high 190s.

Thanks for the reassurances, it was just kind of startling when comparing my numbers with random riders on Strava who have a much lower HR despite being faster than me. But eventually I starting finding ones closer to my own. Seems it's just a highly variable thing and the 220-age rule is not super relevant.

There are two ways to get faster:

1) Efficiency based gains (aero, rolling resistance, reducing drivetrain friction, etc)
2) Increased fitness

Just keep riding your bike and your avg speed at a given HR will increase.

And yes, 220 minus your age is ballpark, but it’s like the Polo Grounds of ballpark.

That's a good point. My bike is heavyish with 38mm tires and an 8-speed Alfine hub that I effectively spin out at ~23mph with so I leave a lot on the table in terms of speed when I'm going downhill or downwind at all. This all despite being in probably the best shape of my life thanks to covid biking.

This is a bit counterintuitive but a lot of the time it's because they're fitter than you so can perform as well or better without exerting themselves as much.

My average speed on a 50mi ride has gone down a good 0.5mph or more this year. I think it's probably because of the 20lbs I put on during the pandemic (less trips to the store + being sick of cooking means more frozen pizzas or nuggets for dinner, lol). I'm still on pace to do just as many miles as last year (3500), but with the extra weight it's just taking longer each ride. I need to start counting calories again.

I'm trying to find a new set of tires for the wheels on my bike. They came with pretty narrow (25mm) and slick (CONTINENTAL Ultra Sport II) tires that I want to replace with something that can at least sort of handle crushed limestone. The specific wheels are DT Swiss P1800 Spline 23's. I'll probably end up using them 80% on pavement and 20% on crushed limestone, and it looks like the maximum clearance I have between my narrow forks is just under 32mm. Would 28mm gravel kings make sense or is there something closer to 30mm nominal?

Appreciate any help, I realize I'm sort of trying to make my road bike into something it isn't, but I really really like it and feel like an actual gravel bike would be overkill.

My HR will be in the 160s for 17mph at like 70-80 RPM and 170-180 for 20ish mph at the same cadence (I can't do that for very long though without a some friends with me).

There's honestly too many variables involved to compare your own HR against your speed. If it's hot, my HR goes up fort any given effort. If there's wind, my speed will change at any given HR. If I've ridden a lot of endurance over the past couple days, then my HR will generally stay lower due to my heart being fatigued,

Only thing you can do is look at long term trends for HR vs power (real power measured with a power meter, not a Strava estimate) vs interval where you can strip out other variables.

There's a decent number of slicks at 30c, but I dunno how many measure to 30mm:

You don't need gravel tyres for a crushed limestone surface. Just use any regular road 28/30mm slicks and you'll be fine. Doubly so if you go with tubeless.

If there's shards that would penetrate a road tyre they'll penetrate most gravel tyres as well unless you go for some giant armoured monstrosity, which doesn't seem appropriate for only 20% of the time.

If it's well maintained (ie. actual limestone throughout and not a dirt base coming through everywhere) there won't be any muddy sections or anything. Even if wet a limestone surface will be absolutely fine on a wide slick.

Its one of the reasons why riding to heart rate is a very vague way of measuring improvement in fitness. I've had rides where I've been in the 160's when the week before I was around 150 for the same 'effort' and that was entirely down to not looking after myself very well that week and maybe having a bit of a cold.

Its better than average speed, but still needs to be looked at in the broader sense as you said.

shikoros run notoriously small and 33 should be drat close to 30-31ish, but they’re a great all around tire

I've had the bike for about 4 years and haven't had any punctures yet on the paved trails I ride. So unless the crushed limestone is way harsher, I don't think I'd need an ultra puncture resistant tire.

Price isn't really a huge concern for these. Nothing that's like $200/pair or whatnot, but most bike tires I've seen seem pretty reasonably priced.

learnincurve posted:

Good point! I don't usually ride when it gets below about 45 degrees F, so I'm not too concerned with winter performance. My current tires SUCK when pavement gets wet because of how slick they are at this point, so being able to handle normal temperature wet surfaces would be great.

One other thing, I'm currently running tubes but my wheels are apparently tubeless compatible. My spouse has tubeless on their Contend and the only difference I've seen so far is that tubes don't need goop every 4-6 months and retain air much better week over week. That's all on paved, so if tubeless really shines on rougher surfaces then I am totally happy to switch over to tubeless. Really appreciate the help y'all!

Tubeless lets you run much lower pressure for much better comfort on rough stuff, and it additionally solves most briar/thorn/flint-related punctures. If neither of these are a problem then tubes are cool too.

For road, I don’t get enough punctures with tubes (0.5 per year on average) to bother changing anything, but people in my club have had nightmares with tubeless, admittedly as they don’t know the ropes / have the right equipment.

- Some people (for road) need or want pressures that are higher than tubeless sealant works well with e.g. just for rider weight reasons. The recommended pressures on the Silca tyre pressure calculator page work fine with tubes anyway.

- Seemingly only a few kinds of sealant actually work well at road pressures. Stans does not. Whatever Giant shops put in their wheels does not.

- To seal anything the sealant doesn’t fix magically, you need plugs. Again, most types don’t hold at road tyre pressures. You need dynaplugs.

- I’ve seen people offer to help an inexperienced rider change a flat, then withdraw their offer when they discover it’s a tubeless setup and they will get covered in goo.

What insane pressures are they using?? Max 4 bar/60 psi with Stan's works great for me with a 32mm tyre, and my TCR came with 7 bar/25mm tubeless setup and sealing and such works fine? Those are the recommended maximum pressures from the tire manufacturer by the way.
There's no reason to go higher anyway, rolling resistance will only increase because of the reduced compliance over bumpy surfaces. On bad roads 2-3 bar is excellent.

Arigato, Racists.
My canyon commuter has a lot of front disc rub problems I'm trying to solve. It has hydraulic brakes but a QR axle (:argh:), and for some reason (this is probably the core issue) the hub seems to shift over time, moving more to the left. The tightness of the QR seems to be a big factor, so perhaps it's loosening and allowing the wheel to shift a bit in the dropout.

I could reposition the caliper, but then I would just be allowing the wheel to sit off centre. Otherwise I can just keep resetting the wheel, but I have to do this every week or two at the moment which seems stupid. I'm also worried that any movement in the dropouts is going to cause them to wear away and make this problem even worse. Any ideas on the best course of action are much appreciated

This just seems like the standard QR+disc brake nightmare though, I probably wouldn't have gone for this bike if I knew it had QR for the fork
