What did you do with your bike(s) today?

I second that.

I would not think Chinese made freewheels from AliExpress have any sort of precision or quality to speak of given that neither Shimano nor SRAM licence their designs or metrics to Chinese third parties.

I assume you are talking about cassettes when you talk about "freewheels"?
They don't have the same shift ramps so perhaps do not shift quite as crisply. If you choose to look at the photos and videos posted and then have another think, perhaps you will change your mind.
The ability to match the profile of the chain with the gear teeth is childs play I expect (I am no engineer however) compared to manufacturing that single lump of aluminium alloy into 5 gears that spline onto the freehub.
Ridden 110 k only with it so far but it was fine. Remains to be seen how it lasts.

Found a 15mm cut in the rear tyre (TLR) Still holding pressure ok so drizzled a bit of tubeless sealant into the cut. Not sure if it will work but tyre is nearing the end of life so no loss anyway but if I can extend the life a bit worth a try

[CmdrBiggles]

Mmm-hmm.


Cassettes <~> freewheels.
Olde Skoolers don't sweat semantics.

Material, it's thickness and Rockwell metric), tooth height and offset, spacing of cogs, etc. are all taken into account and designed-in to the shift performance by Shimano and SRAM.
Third parties... What are they doing? crystal ball gazing??

But at the end of the day, if it works for you and you are happy, well and good, and dandy.

Old schoolers called them "clusters" at least that is what they were called back in the day around those I hung out with. Freewheels may go back even further.
Shift ramps and tooth shaping are what is important for shifting. I posted a video that addressed that.
It shifts ok nonetheless.
The discussion about the durability of the larger aluminium teeth on that cassette is prior to your post. The aluminium gears are thicker and have more teeth being the lower gears.
I will report back if it wears out quickly.
I had a quick look at that ride I did on it. Weighted average power 207w and max 903w. I wasn't going flat out but that is about all these old legs had. There are significantly faster riders on here. GB and Mr P are 2 of them.

I ordered an all steel one the other day (what I intended to get originally). Still pretty light.
May start a Chinese cassette thread.
I have been using 11s Sunrace cassettes on my other bikes for some time. They are a very good product imo.

[CmdrBiggles]

^^^ 903 watts!!?

What in God's name are you and that g-boaf guy sprinkling on your goobies in the mornings!?

The highest watt I have output is 287w.
I needed a stop for a latté, lamington and skyr topping to recover.

[warthog1]

It would have been a short lived burst up a hill. I cannot sustain that for any length of time whatsoever.
The top sprinters put out way more than that and can put it out for much longer.
I am an ageing neverwas.

[CmdrBiggles]

Okaaaaay.

And now, we interrupt this prattle to return readers to regular programming of the thread.


Meanwhile, Warty could start another thread about Cheaper freewheels/cassettes/clusters, maybe subtitled as "A Work in Progress" .

I don't think it would stop any airleak.
It needs to be inside the tyre carcass to form a clot and plug the carcass when air escapes afaik.

It might fill the hole and stop grit getting in there. I have used shoe goo for that before.
You can buy tubeless tyre patches applied from inside the tyre. I have used a tube patch for that before but the tyre was short lived as it punctured soon after elsewhere and I binned it. Tufo speedero. Not recommended.

[P!N20]

max 903w.

The AIS called, they asked if you had a passport and were available later this month.

It would have been a power spike probably.
Just put up those numbers to show the el cheapo cassette can take a bit of force without playing up.

903W is not that unusual. This is my power curve.



When you consider exactly how you have to abuse your machinery to do this with 61kg it may explain a few wear items! Admittedly 1000W is exceedingly painful. 'Vision going black' sort of level of painful. I can sustain it for about two seconds. And there's usually not enough motivation in the world for me to actually do it.

One of the guys I ride with occasionally can genuinely hit 1500W.

Luckily I don't have a power meter .... it would be embarrassing

[ Data from IGSPORT iGS800 fed from SRAM ForceQuarq spider-integral double-sided power meter, magic zero calibrated,
50%L / 51%R ]

Proof plain in view, that I am an oh-so-leisurely roadie — no hammering of anything; no rush, no compunction to get ahead or lead, nor break speed limits (but that might change!), and I do enjoy the downhills (and sustaining a decent speed afterward!) more than the uphills...

People with deep pockets may relish thrashing their bikes and components and easily fetch another whatever-it-is that they've buggered, but for the rest of us, it is a very steep replacement cost that needs to be sensibly offset for as long as possible, notwithstanding the occasional throttle that will doubtless come up as time goes on.

[Mr Purple]

Drivetrains aren't actually that expensive, provided you don't go beyond Ultegra/Force.

$90 for an 11 speed Ultegra cassette, $40 for a chain, three chains per cassette. That's not too bad.

Tyres though kill me. $110 for a GP5000, 1500km average. I don't mind paying that provided I've got a good story about how I killed it. And usually do!

"That's not too bad..."

SRAM Force DUB chainset: $600.99
https://ccache.cc/products/sram-crankse ... 68fa&_ss=r

SRAM Force AXS 12 speed chain: $63.49
https://ccache.cc/products/sram-force-a ... 6763741400

SRAM Force 12 speed XPLR-XG cassette: $342.99
https://ccache.cc/products/sram-xplr-xg ... 9fc7&_ss=r

Probably higher price still for the cassette in 13-speed (next year?), which SRAM is actively working on, with no change to dropouts, just rear derailleur axial programming.

Anything else...?
Oh, and don't get me started on the replacement cost of front and rear derailleurs if something wicked should this way come...

[Mr Purple]

You’ve just convinced me to stick with Shimano!

I’m still on my first RD. 22,000km and 200 odd KOMs on it. Second FD, but that was because my dodgy Bowman frame was not round enough and it fell into the crankset. That was fun.

[g-boaf]

What in God's name are you and that g-boaf guy sprinkling on your goobies in the mornings!?

The highest watt I have output is 287w.

It's a lot of riding and training. I used to max out at over 1000w around 10 years ago - that's long gone and never going to happen again, my body is just too broken.

It's all about strength in your legs. Hit the gym and do the right workouts and you should see the power increase. Obviously you have to ride a lot - but your average power should go up along with your maximum power.

Josh Mansour (the Rugby League player) has some good workouts you can try for building power:

Go easy at first, learn the right way before you start trying to lift heavy.

[warthog1]

Anyone spot the irony of whinging about the price drivetrain parts but then rolling eyes at the thought of chain waxing.
Again, this bloke has done a tonne of testing and the results in durabilty aren't even close.

Jebus, that's not hard to do, I've even pulled just over the 1000 in a sprint and I've been extremly unfit for the last 3yrs. Some of the Masters Riders in my age group can hit 1500w+ in a sprint but I'll never hit those figures.

That's not too bad . . . I'll see your SRAM and raise you Campy:

Campagnolo Record Crankset $650.66, Super Record is $742.78
https://www.bike24.com/p2277228.html and https://www.bike24.com/p2277299.html

Campagnolo Super Record 12 speed chain: $71.29
https://www.bike24.com/p2277360.html

Campagnolo Super Record 12 speed cassette $341.67 with a hefty discount!
https://www.bike24.com/p2277356.html?sku=968492

All this and I'm running mechanical gears. Haven't had to replace anything yet, only 4,500KMs and I am running Record 2 x 12 but the only cassettes and chains are either Chorus or Super Record, they don't make Record in certain parts. The rear derailleur seems not so bad, a Record rear derailleur is $300.

Still, they are meant to last and are a pleasure to ride. Mind you, the brake pads are extortionate and hard to find.

I went out and rode the bike. It was some crazy scenario where the sun was out and it was dry.

[foo on patrol]

Bought a couple of K-edge GoPro mounts for my outfront mounts. I got given a Hero Black 12 and needed a better position for mounting the camera.

Built up a Sturmey Archer front Dynohub from spare parts in the SA bits box - and it works
Just need the oiler clip....

Gave it a good clean and lube after commuting through puddles last week after the previous heavy rain. This week is looking terrific though - sunny, light winds, 20C every day.
