It looks like my aspero might finally be arriving next week! Looking at some quick and easy weight savings and have seen the J&L thru axles discussed. Anyone had any issues with these or do they seem to be solid? What sort of weight savings would be expected over stock?

Is there any other low hanging fruit weight savings around? I'm getting a Red AXS XPLR build

There are 90+ pages of this discussion here, mostly focused on the regular Aspero - are you getting the Aspero or Aspero5? if the 5 I believe your stem options are slimmer because of integrated.

J&L axles are cheaper options, yes, along with some lighter tires (maybe RH Barlow Pass). If you're getting the Reserve wheels..those are nice, but there are lighter wheels out there.

If money was no object for me I'd go MCFK/Darimo/THM/Extralight/CarbonTI for anything on the frame :D

the 35T inner will be VERY tight. If you drop a chain inside the inner ring, it WILL take off a LOT of paint. I know this with experience from running a 50/34. I think I have pictures of the damage in here somewhere.

Does anyone have any recommendations for longer mud guards or fenders that come off the seat tube instead of the saddle or seat post? My saddle is very far from the back wheel so small mudguards do very little to stop me from getting sprayed.

Only thing I can think of off the top of my head would be Ass Savers, but that mounts to the saddle.

Another type of fenders is the "swan tail" that is attached to the seat tube but is closer to the rear tyre. For example SKS S-blade, but there are many other brands and models too.

Ass savers has the long Fendor Bendor model that is attached to the seat tube.

Is this a common issue with running a 50/34? What size cassette were you using? I found a 50/34 Easton Chainring that I was going to use with an 11-34.

Cassette size doesn't matter except for RD selection. With a normal chainline, you have about ~3mm clearance between the chainring and the chainstay, slightly more at the downtube with a 50/34 combo. When you consider that a 11s chain is about 5.4mm wide, something is going to have to give in a chain suck or dropped chain situation. The ring will flex a little bit, but it's going to take off a good bit of paint. Thankfully, the Aspero has a really thick coat of paint on it. You can take off a lot of it without doing any serious damage to the carbon. A little clear 2-part epoxy and some touch up paint, and it's at least covered and protected.

I switched to a SRAM "wide" crankset and the extra 2.5mm of clearance really helps. I dropped a chain due to a hastilly allingned FD and chain cleared the downtube with no issues. I have not seen any adverse affects from pushing the chainline out by 2.5mm, so that'd be my recomendation for 2x with a 50/34. It might even be possible to run a 50/34 oval, but I haven't tested it as I don't have the rings.

I have my full bike ride wrapped so not super worried about trading paint. Are you saying that with the 50/34 the risk of dropping a chain increased? I am running a standard GRX 600 46/32 chainring at the moment with the 600n derailleur and 11/34 cassette.

No, I'm not saying the risk of a dropped chain increases, I'm saying the risk of damage increases. Risk of dropping the chain shouldn't change much, if any. But, the larger ring reduces the distance between the ring and the chainstay and depending on the design, may be a tight fit at the downtube. When you consider that an 11s chain is 5.4mm wide, and with a 50/34 you have about a 3mm gap betwen the ring and the frame... it will rip right through the ride wrap and every layer of paint down to the carbon if you get chain suck. If the chain gets between the chainring bolt and the downtube, it will do the same up there.

Moral of the story, be very very meticulous when setting up your FD... you don't want your frame to look like mine. I do however keep it well hidden behind KYTEX and a Quarq D-Four.

Hi all, just done a quick search but couldn't find anythig meaningful. Hopefully a few months off yet but I will be using my Aspero as a winter bike and wondered if anyone had got SKS Raceblades mudguards to fit or if there was a betteer option. Not really a fan of mudguards but need them for club rides.

Running https://www.crudproducts.com/roadracer-mk3/ on mine, work well. Only issue is the rear guard could do with being a bit longer for club rides.

Asking for a friend:
Can somebody help out with the correct cable length for a Shimano GRX Di2 setup with a size 51 Aspero frame?
