Cervelo Áspero Gravel bike

[Stueys]

Interesting statistic in the CyclingTips article on Aspero-5 - "As of March 2021, the Aspero, along with the fresh do-it-all Caledonia, made up approximately 60% of Cervelo’s global sales, a staggering fact given the company continues to be a leader in the triathlon world and is best known as a performance road brand."

That is interesting; probably skewed for cervelo given the Tri market where they are so strong has been hammered, and the R5 is now very long in the tooth.

I am sure Spez and Trek are more 'balanced' in sales per genre
But its clear gravel/all road is here to stay...

Agreed, think this is more a reflection that most of the current roadbikes are due a refresh

The R-series and R5 are old because the demand is not there - it is catch 22.

The new R5 is already being ridden in testing by TJV. So it will launch for Tour de France I guess. It is same integrated cockpit as Caledonia-5,Aspero-5. Thankfully it does not have dropped seatstays.

Apparently I'm getting Aspero Apex 1 on monday. Do you guys have any bb/cassette recommendations?

Stock 11-42t with 40t chainring might be good on gravel, but I hate those 2 teeth jumps on a road. So maybe 11-36t? I had ordered 11-30t for 2x GRX version but that might be too much with the 40t

Was there a cheaper Sram bb that fits bbright or is that worth the extra money?

What is the biggest 650B tire people have been able to fit? Are there any small mountain bike tires that will fit even if a little larger than stated clearance?

I'm using the stock 48mm tires on non-stock 25mm I.W. wheels and there's about 5mm of clearance in front and back, I dont know if I would go any larger personally

I currently have a mullet wheelset with a 27.5x2.0" Continental Race King on the rear (XC race tire). I have it on a 30mm internal rim and it just barely clears 4mm to the NDS chainstay. I think it's a hair more room on the DS. I am rebuilding the Easton rear wheel that came with it with a 650b Easton ARC 25 offset (25mm internal) rim as my main mullet wheelset. My hope is that it will buy me a little more clearance, I'm not going to try to fit a bigger tire.

Hi Weight Weenies,

I might have seen this bottom bracket issue somewhere, but I could not find it (large forum).

Yesterday, my grx600 crankarm fell off suddenly. The ridges on the spindle were completely round. Yes, it is a non-hollow-tech (softer) crank than the grx800, but still, the bike is 2.5 months old.

Then, I saw that the underside of the bottom bracket was partially worn away. I never heard any scratching nor felt any resistance.

Your thoughts?

You need to push the axle through from the drive side and attach the crank and tighten. It is easy to do but if you are uncertain bring it to the bike store.

So after sorting out my hanger I managed to fit an 11-36 cassette on grx 2 x setup. No issues so far

I am running 10X42 with a Rotor Aldhu 2X with the wider offset up front on GRX di2. No issues. Different bike though - Factor LS.

Interesting. Got photos of the rear setup?

Yep I will snap a few tomorrow in the daylight and post them up. Took it for a good run today and it's shifting super smooth. Just going to reprogram the Di2 to make sure I never inadvertently end up Big Big but I tested it on the flats and it ran fine.

nice thanks.
im still yet to figure out how to make di2 not switch to big - big.
It does stop 2 short when in the little ring and was hoping it could do the same the opposite way.

So the first thing that comes to my mind is that the preload adjuster wasn't tightened and the bolts on the crankarm weren't properly torqued down. The end cap is for pre-load only, so that won't keep the crankarm on, but even with 1/2 the splines engaged when properly torqued. The other issue, the rub on the arm/shell; in all of the photos with the spindle installed, there is no dust cover. If that wasn't installed, there may have been lateral play that allowed the crank arm to rub. Were there any spacers on the DS side of the spindle? Similar question on the DS dust cover.

I think the only way to do it is to setup synchro shifting. As I recall, that will automatically switch between the big ring and the small ring at a cog of your choosing. I tried that, and semi-synchro very briefly, didn't like it.

I'm honestly not terribly concerned about big-big aside from the possibility of a dropped chain if backpedaling. I think the additional wear issue is over-hyped unless you spend a LOT of time in the big-big, and if that's the case, you probably need a smaller big ring. But that's just me.

{edit} I suppose if you're running a total tooth difference greater than the capacity of the RD, that could be an issue {/edit}
