i’m trying to set up tubeless and having issues. i’ve taped the rim and fitted the valve and the tyre. when i try to pump up the tyre the air just goes straight out between the rim and the tyre. how do i seat the bead/get it to seal. any tips

As others have said, you need to move a lot of air quickly. If you don't have a compressor, your floor pump has to move enough air to get the tire to seat properly so this means several pumps in very quick succession.

Good luck

Definitely not a Code lever. Stock Code levers were never carbon. That's likely a Juicy Carbon lever.
Its from a juicy ultimate, I dont care if i get a carbon lever, I just need a lever that will work with the same brake.

Cool, then look for a Juicy lever. I'm not sure what the issue is here. It's an old lever design that's not used anywhere else on any brakes nowadays.
The problem is, the only juicy levers I can find aren't the same as this lever. they have different holes in different places.

you tried dt already?

A quick search shows that's a road bike? Regardless (road questions are fine here as well) I couldn't find much, or rather, anything on it. I'd just shell out $300-$500 on a new wheel and replace the other one later.

Alternatively swing by a Giant dealer (or email them), they probably have access to some old documentation that will give them a part number for it, and then they can check some dusty corner in a warehouse for the 1 of the 5 remaining spokes in inventory.

I believe what you need is called a Giant/DT hub nipple. In a perfect world, any giant/DT dealer should be able to help you out... if not, get it online / shipped internationally. It would be awful if a 2$ part was the only reason to bin a wheel.

That's true, throwing out a wheel because you can't get a $2 part would be awful. I don't know why I said that, whoops.

I'd buy a few extra of all the different spokes your wheels have (f/rl/rr are usually different) so when you break another or sell the bike you have them on hand. Assuming of course the supplier can get you them.

and make some shaft clamps with a bit of wood and an old inner tube Wink



The first time I tore down a reverb, I f*cked the IFP the same way.

Hard way to learn a lesson, but I haven't done it since. I made soft jaws just as you described after.

You can get rubber golf club clamps that sit into your vice, they're ideal for reverb shafts etc. and they're only £2 off ebay.

Find a mate with a 3d printer and make some 10mm ones, lots of applications, shock body ones are good too. Leave the surface a little rough and use inner tube or a little carbon paste to help the grip

Specialised Stumpjumper 2019 Alloy 29 what size shock, spec says 210 x 50 but Fox web state imperial sizes only on the DPS Evol? OEM only maybe?

I'm picking a chainring size for a single pivot build I'm doing, based purely on the ratios I'd prefer a 30t. Will there be a noticeable difference in terms of pedal feedback between this and a 32t? Its a long travel build so will spend most of its life going down and I really dont want to go bigger than 32 so its just between those 2 sizes. Theres a lot of conflicting accounts out there on this so I thought it'd be interesting to hear what you guys think!

210 x 50 is 8.25" x 2"

if it's mostly going down why are you going with such a small chainring

A 2 tooth difference is negligible. I would pick one and if it doesn't work out, just go with the other one.

Yeah, I forgot approximate, they must just spell it in metric for us ????

should Rockshox Super deluxe RCT fit on YT Jeffsey 27,5 CF Comp 2019 size L?

That depends on the eye 2 eye and stroke of whatever the factory shock is, if you can find one that matches then sure why not

You should run a narrow-wide profile chain ring. An outer bash guard really does little to help keep your chain on. A narrow-wide chainring will be your most effective solution.

This is true. If your derailleur doesn't have a clutch - and I think the stock SLX model doesn't - you should fix that, too.

Thanks for those recommendations. I will definitely be making changes.


Since posting this I have switched to a One-up 32 tooth NW chain ring and have removed my front derailleur/lever etc to make room for a dropper post and lever. This leaves me with a 11-36, 10 spd cassette and SLX rear derailleur. What 1x11 config should I be using? 32/42? 32/46? Derailleur? Keeping in mind this is with 26" wheels. The type of riding I do is uphill climbs and technical trail riding.

because rockshox super deluxe has this extra air tank so it wider than the stock shock

I have seen jeffsy with shocks that have piggy backs there should be more then enough room to fit it.

Here's a link to bikemag that shows a jeffsy with a shock that has a piggy back
