[#12648452]

Sat at FoD it seems i lost a bolt on the Slayer.

I've been informed by RM in UK they don't have any in stock here... They seem to have them in the US potentially and certainly as part of a $189.99 kit. Eeeeek

https://intl.bikes.com/fr/collections/parts/products/pivot-bolt-kit-slayer-2020-2022?shpxid=8fc28bcd-7ad6-4e26-a72e-f4888ae64f8d

So it seems RM in the UK don't have the bolt... i can buy a full pivot kit from the US for $189.99 lol. Eeeek.

That's the offending bugger, 13 in the middle. The flat of the flat head is 15mm exactly and fits into a 1mm deep slot in the chainstay, So assuming the head clearance isn't an issue, i could just use one of these
https://www.ebay.co.uk/itm/294634386042?_trkparms=amclksrc%3DITM%26aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20211130125621%26meid%3D9269a75c77914dcfa52fdb25f4cdc524%26pid%3D101465%26rk%3D1%26rkt%3D4%26sd%3D294634386042%26itm%3D294634386042%26pmt%3D1%26noa%3D1%26pg%3D3817808%26brand%3DUnbranded&_trksid=p3817808.c101465.m3507

With the 15mm washer to go into the chainstay it should fit nicely, the only downside will be that the whole bolt is threaded, not shouldered on the bearing. (unless the head is an issue and hits something, but i think it's just aesthetics that it's flat/flush.

Other thoughts, ideas, appreciated.

Check accu.co.uk

They do a vast range of precision nuts and bolts, most random thing I've needed was a threaded mudguard insert for a carbon fibre road fork, accu.co.uk had it 👍

Yeah as above or you might find you have a local place like I have that does literally every fitting in the world.

https://metalworksupplies.co.uk/

They often give them out for free as well rather than bothering charging for 1 item.

Two good RM stockists I know of that pretty much always keep spare parts in stock and run a fleet of RM demo bikes themselves, so might be worth giving a call if RM distributor in the UK has none...

https://www.zerobikes.co.uk/en
https://www.setchfieldcycles.co.uk

Fingers crossed you get something sorted...

Emailed both yesterday mate, but thank you.

Zero came back to me and are trying to help.. but they don't have one spare/available at this stage.
AW Cycles are my local dealer who i've put in discussions with RM in the US.... but i don't know how easy or quick that will be.

Any thoughts on using just an M10x1.0 with a 15mm washer (assuming the head clears wheel on rotation), would the threaded part where the bearings are be an issue ? Or is it just a complete no-no.

Somewhere like squealet suggests would be my first try.
Or of you still have one from the other side to copy I'm sure you can get one made for a lot less than the £200 it would be with shipping and VAT. How strong does it need to be, could you even 3D print one?

I still have one from the other side yes.

I'll shoot to my LBS to see if he has one as well. Well, something similar anyway

The kit itself isnt

COMPATIBILITÉ
Slayer Alloy 2020
Slayer Alloy 2021
Slayer Alloy 2022
Slayer Carbon 2020
Slayer Carbon 2021
Slayer Carbon 2022

But it's not impossible the bolt could be.

Close at 22.5mm how much do we care about the extra 2.2mm hmmmm

That’s pretty poor on the Rocky Mountain / uk distributor front if they don’t have any spare bolts for a current model just sold.

Will suck if you have to buy the full kit from America for the cost.

@weeksy try apex Fasteners based on the Slough trading estate located on Ipswich road number 512.

I think I’ve got one of the Trek bolts (a broken one) in the garage, if it would help to get some dimensions off it. Spare was bought from pedalon

Yeah I can get one from Pedalon but slightly concerned about length.

24.6mm is quite a specific length so most likely a critical dimension, get the Trek one and take 2.2mm off the end of it.

I can’t imagine it’s a RM only bolt (actually being the bike industry I can) can you take it to your local nut and bolt shop/ironmongers and see if they have one? Or bodge it with something generic? Several of my bikes have had all their pivot hardware replaced with standard bolts when they invariably break in Morzine or have been discontinued.

I would imagine it is a RM proprietary bolt, possibly model specific too.
Might be worth taking the remaining one to a small engineering company and see if they’ll copy it to make some spares. Unfortunately the price might start to make the RM kit look not so bad

Well that's the question i don't know the answer to, hence me asking that here 😀

But no-one has given much on that side of things yet. the length i can sort with a 25mm bolt, the head i don't think is an issue. The main issue is the flat section which is where i guess the bearings sit in the chainstay. Is the flat important, or can it still be threaded in there. The rest, could be fudged easily enough.

Trek do a M10x1x25, so could be shortened, but it has 80% of it threaded, whereas the RM bolt is about 30% threaded.

Hopefully one of the RM dealers will come up with something today as a plan... Until then, we wait impatiently 😀

Same thing mate, in terms of Emails anyway. The main RM HQ is who i've been mailing.

I'd say we will get one of these (well, 2 actually lol) it'll just be a question of when and how much.

I've got FoD and Cmwcarn this weekend, but sod all idea what i'll be riding.

You might as well get the trek one in at 25mm and see if it can be made to work. You will then see how much of the bearing is supported on the non-threaded section. Might be ok as the pics of the trek bolts all have different length threaded sections.

Cookson cycles have it too at 25mm and it doesn't look to be 80% threaded.

We ran into the challenge of even finding a spare mech hangar with Rocky Mountain. Crazy on a £4k bike.

Brilliant bikes, seemingly poor/very small UK importer and a lot of proprietary stuff on thier bikes.

Mech hanger was OK, i've got one of those.. Pila make one that's correct for mine..

I'm well happy with the bike... it's a great thing for sure.

Weeksy can you post up a pic of the one you still have so I can get an idea.

Ive got these:

[url= https://i.postimg.cc/7Y5hPgVR/Imagebolt.jp g" target="_blank">https://i.postimg.cc/7Y5hPgVR/Imagebolt.jp g"/> [/img][/url]

They are 31mm long roughly

I'm sure they came off a 2021 Orbea wild fs

Would they be any good?

31mm i can make shorter, well a mate can... i'm sure he'll have a thread cutter in 1.0 as well.

Do you know if it's a 1.0mm thread or a 1.25 mate ?

Are they the Trunnion bolts ?

Saw these cheap on Amazon one on the right looks... probably an angled countersunk head though - might take a bit of dremmelling. Or contact the seller, ask if he's got anything that'd be nearer.

Not sure what thread it is mate sorry.

This is them:
https://brilliantbikes.co.uk/orbea-spares/3677-orbea-wild-fs-linkage-seatstay-kit.html

They are from the top of the seatstay where is connects to the rock linkage

Linkage seatstays bolts x 2
12x14x3.2 washers x 4

That implies they're 12mm diameter if the internal diameter of the washer is 12 on there mate, so i'm afraid they wouldn't be any use... but thanks tonnes for trying.

And that's me being completely wrong lol. Well if StuF's link is correct that implies M10 is 12mm ? lol.

M10 is nominal 10mm diameter... if you look closely at the drawing for the shoulder socket screws in StuF's link, the threaded part isn't the same diameter as the shoulder... which would account for the difference.

Basically I think it'll be an issue. The flat part is most likely designed as a good fit to the inner bearing race. A threaded shank won't be a good fit and you'll probably find it a loose fit meaning it'll rattle and at best bug the poop out of you. It needs that smooth shank from what I can see.

Whilst not the answer i want, it is sadly the answer you'd expect.

I had a similar issue on my Nicolai where a bushing had worn on the Horst link. Didn't really want to pay out the crazy price/shipping but in the end I had to. Admittedly it wasn't the same sort of money you're looking at for the RM kit.
Other than speaking to some small engineering firms and trying to get something made up (it shouldn't be too hard to make something work, it's just finding someone to do it!) or waiting for one of the shops/dealers to turn something up you're a bit snookered by the sounds of it 🙁

Tried 3 Eng firms, none are interested unless you want 100s of them. Which i guess is fair.

If i have to pay $189 then that's how it is and it won't make me smile, but i'll pay if i really have to.

It often comes down to either pay for the parts or have a lump of useless carbon/alloy sitting there in the corner! Bespoke bike parts are a pain in the ar$e!
