OK, I'm not sensing any consensus here. My choice is between kojak and comet because they both weigh around the same and that's half of the marathons. I can patch and change a tire very quickly but if it became a constant thing, then I would switch back to marathons. I think I just need to try one of the smaller slicks and see how it goes where I ride.
As for my friction drive (when it comes), "supposedly" it is designed to not eat the tires up. Again, something I will have to wait to see. If it does, then I can put a marathon on the front only, where the motor will be.
Does anyone actually have comets on their bike?

They don't offer orange cables or I might do that, to keep up with my SF Giants theme in reverse from my NWT (which is orange with black). Black with yellow cables looks really sharp and I can get a yellow handle but otoh black bikes don't look so good when dusty and they aren't as visible. Still mulling it over
The black/orange brompton is gorgeous - but the brommies have about half and half when colored. For some reason, the pakiT rear triangle and fork kind of disappear rather than balance the color of the frame the way the brompton does. Probably because of the size imbalance in width of tubing.

Choosing parts was hard but at least there was a reason for each choice. With color it is purely subjective so it's even harder, lol.

I actually have a Tern carryon bag that I removed the strap carefully from and restitched the bag cover. I can use the straps to carry the pakiT when I go in stores, so I will hold off on a handle. It's a great strap, quick locks like on a burley travoy. I can keep the cover in my trunk.

I forget where I got this orange pakiT picture but I put my own seat bag on it to see how it looks. I am going to have them leave off the pakiT black and white stickers and just put those in an envelope if I decide to use them. I like the cleaner tube look. Test ride is this coming Tuesday!!! Yay!!!

Have ridden both Kojaks(folding and non) and Comets for thousands of miles over the years. Folding Kojaks will be the lightest of all three. In 349 ETRTO you may also want to look into Velloto Fantome https://dinokiddo.me/shop/wheels/vel...2%8A%E8%83%8E/

and/or Kousac(though I think someone on Facebook gave them a bad review):
https://www.ebay.com/itm/Brompton-Mo...-/192119383015

Anywhoo, back to Comets vs. Kojaks. For me both have minimal flat protection, ok when new. As the miles pile up and the rubber gets thinner - they get more susceptible to flats. Glass in my area. Both roll pretty fast.

Primo Comets:
Schwalbe Kojaks/non folding on a pakiT:

I had Kojaks on my Birdy and Brompton. It is of course hard to say one is worse than another; but I didn't do well with Kojaks. It could be subjective that I think Comets are tougher. Or it could be that the anti-puncture strip (which the Kojaks don't have, right?) which makes the Comet tougher. Not that the Kevlar strip prevents punctures.

Although the fast, sporty, tread-less slick weighs just 295 g (35-559) it still has a RaceGuard protection belt <<kojak.
or are you talking about some other puncture strip?

So BF got back to me and said if I want a 105 rear der I have to get a new chain and new shifter for their 8 speed pakiT. Not something I need or want to do. If I can't use a 105 rear der, because BF says they don't make them anymore for an 8 speed, any suggestions for alternatives to the entry level claris? Will Deore XT 9 speed work? That's better than claris, pretty durable and shifts well. Any other options?

That doesn't sound right. Derailers do not have speeds. They have pull ratio and teeth range and max rear cog. Any 105 should work with 8sp. Road groups haven't changed pull ratio.

Well that's what I thought. Is it the chain size that's an issue maybe? I'd hate to think he was trying to upsell me to a new groupset instead of just a better rear der, like I asked.

I'm a little vague on this, but I believe the latest 11-speed road derailleurs have a new pull ratio. If you can't talk BF into sourcing a 10-speed version (it's 8/9/10 compatible) then just take the Claris and do the swap yourself at home.

They are saying the change is after 9 speeds...and I did find some info that might support that. So I'm looking for a 9 speed rear der that's better than claris. There is the sram x4, which is inexpensive as well, but the x3 on my NWT works very well. I'm getting the sram grip shifter so should be compatible. But I'd like something that doesn't weigh 300+ grams and isn't all plastic. :-(.

Your Deore XT idea will work. That's a nice derailleur.

Ok I learned something here. The main thing is that shimano managers are a bunch of dfckheads since the advent of mtb 10 speed and their dynasys pull ratio, breaking backwards compatibility. That trend continues with their 11 speeds which is not compatible with anything else.

If I were you I would simply source a 105 off ebay.

I have this 10-speed model (sorry, I'd forgotten earlier) that I used on a 9-speed bike. Same pull ratio, works great, it will work with SRAM's Shimano-compatible 8-speed shifter.

That's perfect, I can pick it up for $40....I'll just swap after I get the new bike, thanks!

So I sent them the link to this rd...here's the response: We want to put together a bike that will meet your needs but also perform well. In our experience mixing parts intended for one chain/cog width with another does not end up well.

So, before I buy one, I just need to double-check. It will work with the sram max grip shift/8 speed? It will work with an sram 8 speed cogset and sram 8 speed chain?

If that's true, rather than argue with the guy, I'll just pay for the claris in my build and then swap it myself after.

Yes, it will work. The cage is much wider than the pulleys to make room for Shimano's floating top pulley, which is the secret to their index shifting working even if the derailleur is slightly out of adjustment. BF is giving you grief because they're afraid you'll have a shifting problem, then blame them for mismatched components.
