What tubes am I going to need for my new bike?

most bikes aren't set up tubeless when you buy them, so it will come with tubes. Standard 700c tubes will work fine, you can probably set up tubeless if you want, but if you want to just get out and ride your bike with a spare tube for now, that works too

phew, thanks! When you say,

you can probably set up tubeless if you want,

Do you mean, run these particular tyres tubeless? Or just at some point get some actual tubeless tyres?

Lots of bikes come tubeless ready, it’s just that many bikes are assembled 6 months in advance and the last thing you want is the tubeless sealant dribbling all over a shiny new bike whilst sitting in a warehouse. Dried on sealant is a nightmare to clean off.
Check the tyres are tubeless ready though - some companies cut corners by shipping bikes with low rent tyres and unsuspecting mechanics find out when the tyre pops off the rim whilst being inflated, spraying everything within 5m with sealant (been there, done that 🤣)

Do you mean, run these particular tyres tubeless?

Looks like Vittoria do tubeless and non-tubeless versions of the tyre - the former will be marked TLR or TNT.

Am I right in thinking that inner tubes are still handy things to have around, even with tubeless tyres?

Yes, still useful to carry one as a fail-safe in case you get a hole that is too big for the sealant to seal.

As above, you can run tubeless tyres with tubes in any case. To convert to tubeless you will need sealant and possibly a tubeless valve and rim tape (unless the bike itself is described as tubeless ready, in which case they may be included).

(took me so long to type - basically a repeat of what frogstomp just said.)

Also though - the grey or tan sidewall will tell you if you have tubeless-able versions

A set of anchovies/tubeless plugs is worth having. I'd thought they were a bit of a gimmick but having used them about 3-4 times in the last year, they are brilliant. Take 10s to insert and seem to create a permanent fix. I still carry a spare tube but it's a long time since I used one.

Something like this: Peaty's version will do it - but there are plenty of other cheaper options that most likely come from the same factory.

Well you can stick with tubes, which these days will cost you about £11 for both wheels

Or you can go with the new tubeless system, which will cost you ...

Air-proof rim tape - About £10-£15

Sealant - £10-£20

Valves - £10-£20

Crush cores - £45-£75

Probably a new pump(track type) £40-£70

And of course you'll need to buy and carry with you always, a spare innertube(Costing £5)

Crush cores – £45-£75

Are people using these in gravel bikes?

Sorry, missed that bit. Must be my bias 😉 OK subtract cores, but i think the point still stands that since the concepts inception, costs for it have spiraled.

The thinner the tyre, the more tubeless is a faff.

Back to tubes on my commuter 700x42.

Those cushcore type things must depend on where your riding is, cos I've never felt the need. Or maybe how soft you run your tubeless tyres?
We had to get a tube at BPW the other week - £8!

[i]Probably a new pump(track type) £40-£70[/i]

I can save you some money here - noticed last week Lidls have their pumps back in stock. It's all I need to pump a tubeless tyre up - and though they've gone up in price (were £7.99) a tenner gets you a decent track pump.

can only speak for MTB, but this feels like a victim of marketing and a lot of double counting...

Or you can go with the new tubeless system, which will cost you …

Air-proof rim tape – About £10-£15 probably already on there

Sealant – £10-£20 for one bike this will last you a couple of years

Valves – £10-£20 probably included. the valve cores might need replacing occasionally. A few quid for a pack of 20.

Crush cores – £45-£75 I like mine, certainly not a necessity, but as a like for like comparison, https://www.tannus.co.uk/products/tannus-armour-29?variant=41578353787056 an insert compatible with a tube is £35 per wheel.

Probably a new pump(track type) £40-£70 any normal track pump will probably do these days so you either own one, or need to buy it anyway. And certainly will work with an insert in there.

And of course you’ll need to buy and carry with you always, a spare innertube(Costing £5) maybe in the back o beyond, but certainly not always. If you did get the inserts, not needed. your existing 26 will probably stretch to it if needed.

Terreno Zero come in wire bead, folding and folding TLR (tubeless ready). Do you have a link to the bike you are buying?

It's one of these but I can't see anything about tubeyness.

I have however, just noticed the following. So this whole thread may turn out to be pointless anyway 😆

Please note that, based on component availability and other factors, specifications are subject to change without notice.

Probably comes with tubes. These will do it - https://www.wiggle.co.uk/continental-quality-road-inner-tube-1
Choose: Black presta 42mm (assuming it has presta valves, probably does)
Size: 700 x 28-37 tour 28 (the 700x32-47 will also fit)
