Tire rubbing on CS fenders with Moonbeam

AntiVenom

a degree of camber on a 26.7" diameter wheel moves the top of the wheel something like .47" (call it .5 for a rule of thumb) from the bottom. which in millimeters is about 13mm. so an extra degree of camber can make up for a lot of poke.

so yea, you pretty much summed it up. depending on camber and tire "squareness" you can easily need to change the offset 15-20mm

Has CS officially stated how much wider their moonbeam kit is that stock

AntiVenom

no, they wont even tell you what offsets to buy until you are in the purchasing process. but i did some quick measurements before cutting. it is something like 1.25 front 1.5 rear.

edit: I measured the wheels backspacing and using a backspacing>offset converter I got -19.7mm of offset. I would say strasse nailed it. so the issue is 100% not with the wheel building process.
edit edit: will pop off the rear tires here shortly to measure them as well, but i expect to find no problems. mostly just checking off boxes to make sure i get the right measurements for this next round.

That drives me crazy. How can Carbon Signal not describe exactly how much wider their kit is than stock? Just relying on "their" specs seems ludicrous, because it winds up being your exact situation!

The only alternative is to get the fenders, install them, then use some stock wheels (or other generic wheels with known sizing), and then space them out with spacers until you get an approximate fitment, THEN order custom wheels. All of that is gonna take upwards to 8-12 months given how long it takes to order the fenders and custom wheels!

Stock body for me, at best i'd go something custom that i KNEW the specs for. Ridiculous they want whatever the **** they charge and can't tell you what the width of their fenders are, even approximately

CarbonSignal

It's been mentioned several times the width of fenders

I hear you on all counts. The reality is you can stuff enough tire under a stock body.

To be fair, I never asked for the measurements, just their recommendation for offsets. Newb mistake I suppose. I just expected them to read what I wrote and if they weren't sure, tell me what their customers usually run, but with a caveat about it being aimed at X application (x being high camber and low profiles). I woulda just sucked it up and waited the extra 6-8 weeks after installing the kit. Live and learn I suppose.

I combed through the moonbeam threads for future reference. They are not keeping the width a secret.

Thanks for the research.

I asked them directly when I was buying and got a response to the extent that they'd been tweaking their offset recommendation and would tell me when I was purchasing.

Makes me wonder what they were smoking when they suggested my current offsets. Not like I made them up, you can see the screenshot of the email.

Caveat emptor, I suppose. Should have taken the time to do the same thing you did.

Reading through the moonbeam threads, they mentioned something about the fenders especially designed for the moonbeam. I assume you have those?

Looks kind of tight with OEM wheels.

Ordered it all straight from them, so I assume so. I will double check with them. Wanna run a couple of other things past them anyway.

Lot's of room on revised V2 fenders.

Invoice lists v2 fenders but they certainly don't look as spacious as that photo. Wonder what the specs on that wheel and tire are.

As you can see from doocam's number and their recommendations for adding spacers that they continued to push for more aggressive fitment it seems.

Despite the answers on the forum. I was dealing directly with them. I would have expected a better recommend than what they gave me. a range might have been good. they held on to the recommend they gave me like the holy grail. they asked for me to detail my setup before giving me their recommend. Then they gave me something that wouldn't work.

Oh well, nothing for it, I can only really blame myself for trusting their suggestion blindly. I am going to have them rebarrelled to specs that will work for my setup. Money was made for spending, amirite?

I'm pretty sure CarbonZ is sporting fly1 fenders... Notice how sharp the corner of the vent is on his fender and the CS are curved.
Here's a shot of their v2 fenders right off the CS website. The wheel looks like its behind the fender...
