Greetings from Finland,

This question to me is related to fat bikes as I am currently looking for my first entry fat bike. However, I will post this thread under the heading "Drivetrain" because the differences between the bikes I am currently comparing are almost exclusively related to Sram SX Eagle vs. GX Eagle.

The bikes in question are from the Scandinavian manufacturer White (Find your new bike | White Bikes ). The site does not list the fat bikes they manufacture. The retailer, a Norwegian XXL-store, has the initial specs/pictures available in their Finnish site; here are the links: https://www.xxl.fi/white-7fat-pro-sx-eagle-1x12-20-musta/p/1163483_1_style & https://www.xxl.fi/white-7fat-interceptor-gx-eagle-1x12-20-harmaa/p/1163482_1_style

The specs according to the XXL website are identical between these Pro and Interceptor models (besides those marked with the bolded font which are contrasted with the cheaper Pro models' specs given in normal font in parenthesis):

Technical information on the more expensive Interceptor:
- Frame: WHITE 7FAT AL 26 (12x197) (6061 Aluminum Butted)
- Fork: WHITE 7FAT CF 26 (15x150) (Carbon fork) (Pro: Aluminum fork)
- Headset: FSA No.42/ACB
- Handlebar: WHITE ControlBar Pro 760mm
- Grips: WHITE ControlGrip Pro lock-on
- Handlebar: WHITE ControlStem Pro 31.8mm
- Seatpost: WHITE ControlPost Pro 31.6mm
- Saddle: Selle Italia X3 XP
- Shifter(s): SRAM GX Eagle Trigger (Pro: SX Eagle)
- F/D: n/a
- R/D: SRAM GX Eagle 1X12 (Pro: SX Eagle)
- Brakes: Shimano BL-MT501/BR-MT500 (180/180) (Pro: BL-MT200/BR-MT200 (180/180))
- Brake levers: Shimano BL-MT501 (Pro: BL-MT200)
- Cassette: SRAM PG-1230, 11-50T (Pro: SRAM PG-1210, 11-50T)
- Chain: SRAM NX Eagle (Pro:SRAM SX Eagle)
- Crankset: Truvativ Stylo 6K DUB, 30T (175mm M-XL)
- Rims: Sun Ringlé Mulefüt 80SL 32h
- Hubs: (Front: Chosen A4786B-M15-150/ Rear: Chosen A8777B-M12-197
- Tires: Schwalbe Jumbo Jim Performance 26x4.8 Addix
- Pedals: n/a
- Weight: 13,7 kg (Pro: 14,2 kg)

So, basically, the differences relate to the drivetrain components Sram SX Eagle vs. GX Eagle. (There is also the carbon fork of the Interceptor, and somewhat better brakes, and the 0,5 kg lighter weight.) The difference between the price tags between these models is 250 euros (about 280 $). I would very much appreciate any information/experiences with the Sram SX Eagle vs. GX Eagle components; will this difference - in your expertise opinion - justify the pricetag difference of 250 euros, or should I go with the cheaper model with the SX Eagle components?

There seem to be very little rider experiences available from SX Eagle drivetrain (i.e., https://forums.mtbr.com/drivetrain-shifters-derailleurs-cranks/sram-sx-1103031.html ).

Thanks guys!

SX is the new budget friendly Eagle setup. It's going to be slightly heavier than NX and GX, and it will have a Non XD hub, so future upgrades to GX,XO or XX would require a new rear wheel.

I'd spend the extra 250 and get GX, because you are getting more than just a drivetrain. You are moving up to a carbon fork, lightens the front end, nicer brakes, ect. If you upgrade all that stuff yourself, it will cost way more than 250 bux.

Pay now or pay later...you might end up upgrading the SX parts as it breaks, and deal w it along the way. Cheap materials otherwise same tech. Your choice

The SX rear derailleur does not have the pulley wheel like the NX and up. I would drop the extra cash and go with the GX. The shifter and cassette and also way better. I'd pay the extra money for the GX derailleur and cassette alone.

Thanks guys for the comments and feedback! Your answers actually affirmed my initial preference towards the more expensive components/bike.

Nice to hear of the differences between the SX Eagle and GX Eagle components.

I think I've seen that the SX derailleur's adjustment screws are only self-threaded screws directly into plastic -- run away!

Regardless, that 7Fat Interceptor looks like a nice value! My only "wish" for it would be an XD driver hub and GX or better cassette.

agreed. and the price difference to the lower model with that crappy sx kit makes the upgrade a no-brainer.

Thanks for the additional feedback guys!

Some off-topic: It is interesting that for the price of the White 7fat Interceptor you can get a new 2020 Kona WO ”Finnish edition” which comes with same wheels/hubs etc. but with Sram SX Eagle groupset making it component-wise worse than the Interceptor. But the Kona seems to be more respected in brand name and with respect to it's frame because some here in Finland, at least, seem to prefer it over the White Interceptor. Of course, there are differing opinions too.

If only the Interceptor came in black like the 7Fat Pro. I don't care about the fork being alu or CF as I'm replacing it with a Mastodon anyway, so for me it makes sense to not pay for the CF fork.

I would also very much like to have eyelets for mounting a rear rack, but that drops me down to the 7Fat Lite, which isn't really on the table at all.

Can one just replace the GX derailleur for the SX or you need the shifter too, and or casette?

Yes, but I would change the shifter first. I think its the shifter that makes SX feel like crap. Buy both GX derailleur and shifter but use the SX derailleur until it brakes. Thats my advice 😁
