Cervelo ASPERO 1x Road Setup Project // Can it do Both Gravel AND Road?

First! 🙂

The final animation was worth the time you spent making it.

Does any recalibration need to be done to the power meter after the swap over?

Never fear, SRAM lawyers are hard at work filing a patent for an asymmetric pattern torx-ish head crank bolt so that they can sell you a proprietary 24" breaker bar to remove your crank arms. Oil slick launch edition coming to a stocking near you, December 2024.

Can't you not just use a chainwhip to remove the chainring

Better than having to replace the entire spider/pm once the rings wear out. Easy enough.

And they say SRAM is more intuitive???? No.1 rule in design, KISS (keep it simple SRAM)

At least it didn’t start ”for those people who still have a threaded Sram chainring” 😉

Do dual chainrings for this system exist? I have loste track of the 1001 SRAM chainset options. One could ask why it screws on from the bike side. Would have been nice if you could remove the chainring with the cranks staying on the bike.

The change to threaded chain ring make little sense on 1-by systems. Now we have to remove the crank to swap chain rings. Guess I’ll stick with my previous generation 4 bolt power meter spider – where I can swap rings without removing the crank.

Thank for putting this together @gplama it answers my questions when I first do your IG post. One question left :) I’m assuming the same applies to 2x chain rings? Thx!! And I don’t get why ppl are angry. Better then throwing away the entire chainring and replace it with a new one. That was bad design.

Why doesn't a chain whip with a long piece of chain work? Seems like it was made just to sell another tool.

Nobody wants tools that only works on one product with a proprietary standard.

We don't need this. Boycott sram

Why can't use a chain whip, while standing on the paddle?

That is cool. There should be a way to do it with the chain on the bike no? Affix the crank arm and spin the rear wheel backwards like a big lever? Or a chain whip? You just need to hold the crank still. I’d have to see it. But I wouldn’t buy a sram red so I won’t know.

Looks like SRAM is starting to copy Campagnolo with proprietary tools.

I'll stick with my 4iiii power meter. much easier to get off. This almost looks like it's overly complicated overly engineered, a solution for a problem that does not exist 🙂.

If they can do this, why on earth make a non-replaceable one 🤯

Seems like a chain whip with a long piece of chain in a vice would do the same job.

I was expecting an Earth-shattering kaboom!

So crunchy.

We definitely need to move this direction for the 2x chainrings. I have fully upgraded my road bike to the new Red with the exception of the new crank/PM chainring with hopes it'll happen.

It's also worth noting, at least here in the US, that it's cheaper to buy the Red XPLR crank arms, PM spider, and chainring all separate instead of as an assembly. $50 cheaper, which almost covers the cost of the tool.

not on SRAM, but there is a certain mechanical satisfaction of using a well designed tool on your bike

Sram the jokers

I have the new Red 1X and I switch chainrings between a 46 and a 42, I actually like the threaded ring better when running the PM. Fewer items that can be stripped or seized.

Though I don’t have SRAM threaded chainring and there is no plan to have in the future, I want to have this tool and use it just for fun😂

Hi Shane. Reducing number of teeth on a chainring from 40t to 36t, do I need to bo change anything else? Maybe a different chain? Thanks.

Great video showing how this all works!

Can you change the chain ring without removing the crank from the bike?

Can I use on 2x? Thanks

Anyone try just using a regular chain whip to remove the 1x ring instead of buying the $112 SRAM tool?

Is it impossible to use this tool for changing chainrings on the new RED axs built in powermeter?

I’m not sure what was wrong with the bolted chainring interface of my 2023 Force power meter crankset. Easy to maintain with universal tools. That new chainring looks like it has a lot of expensive machining to solve a problem that was solved decades ago with simple bolts. And sufficiently proprietary to exclude aftermarket alternatives.

What?! I was told you couldn’t remove those rings! I just bought chainrings and a power meter because of this.

SRAM makes things more complicated and expensive. Another example of how they forcing one to BUY ANOTHER EXPENSIVE tool to remove/fit NEW/EXPENSIVE chainrings.
