Obviously as difficult as the XR4 Comps, same carcass but different tread at a guess.

I can't comprehend how and why they fitted non tubeless wired tyres and then still why they tubelessed them!

They got them much cheaper - and it worked. I have fitted non tubeless as tubeless before.
A motorcycle tyre lever is a great tool to have ... just the small one.

Is it as tiny as it looks?

Minion DHR fitted both ends. Added 250gr of weight.

What a ballache though.

That back tyre’s fitted the wrong way round.

Oh FFS, you may be right. Lol. I'd lost the plot by this stage. Ha ha ha

The ones I changed had tubes in.

To be honest after a few hours of mucking around with stuff in the garage when it's getting late and I'm hungry I start making mistakes. At the weekend I stripped a shock, fitted a Megneg, reassembled the shock, and the bastard wouldn't hold air. Then I noticed I'd forgotten to fit one of the seals. Had some food and a glass of white, then left it to the next morning.

I was joking. I’ve done that more times than I care to remember.

Hahahahaha you wanker... i'll still have to check in the morning.... I'd have sworn it was right... but hey, you never know when you're moody and finger hurt from trying to get them on and off for hours !

I've also got a bit of a weird Qn regarding the fitting of the rear wheel, as @irie has owned similar he may be able to help.

It looks from reading here that someone else noticed, but may or may not be the same issue.

I’ve also found fitting the rear wheel to be more difficult than it should be, as the hub end caps are a smaller diameter than the dropouts. This means the rear hub ‘floats’ in between the dropouts while you try to locate the axle. It’s a bit like fitting a regular front hub to the oversized Torque Cap dropouts on a RockShox fork.
It still fits of course, but it’s a bit faffy, even more-so when there’s a chain and derailleur to contend with. The only reason I can see for the design is if Bontrager and/or SRAM is going to release a rear hub with oversized end caps to fit the oversized dropouts. That’s only a guess though – we’ve had zero clues from either company.

When you fit the rear wheel it's not exactly flush in the dropouts, there's a gap between the hub and the mech hanger, all other bikes i've had, when you put the wheel in, it's the exact same width as the chainstay. This is the first bike i've ever known this one. I read a review which stated similar, but it wasn't quite clear. However it looks to me like when you fit the rear axle, it pulls both sides of the chainstay together taking up the space/slack between the wheel spacers and the dropouts. Everything then runs sweetly, but i worry that's not right and i'm missing a spacer or something.
Looking at the diagrams on the Trek website, i don't think i'm missing anything though.

Our Fuel EX's rear wheels fit flush but they're alloy frame whereas yours is carbon, so that might explain the difference. Suggest you call Balfes workshop and ask about fitting, and you could also look at an exploded parts diagram on the Trek website to see if any parts are missing.

There's not a lot to the back end dropout area, so i can't see me missing anything.

Re the back wheel. With the BFe , I thought I had the wrong "Boost" size for it. I didn't - but there was 5 mm of air between the end of the hub at the drop out. All gets pulled back into line by the axle - and Cotic said it is "normal". However that has absolutely nothing to do with a Trek

No, granted, but it's a distinct similarity upon a theme.

I'm fairly happy i'm not missing anything but my LBS Banjo Cycles in Newbury used to be a Trek dealer, so i may drop in to see the mechanic there, Will. Have a quick chat and just get assurance from him.

I don't think you're missing anything. With our alloy bikes there are no loose spacers, the rear wheels just drop in and out.

Whilst on the FlareMax you do have to physically spread the mounts to get the rear in ( at the same time as locating the chain and getting the disc into the calliper ...

Yeah the G170 requires a tiny bit of a pull outwards.

Hey weeksy, would you like me to measure the outside width of a Alex MD35 rear wheel with 12sp Deore cassette?
