    Anyone got any tips for chainsuck protection

    Get yourself an anti chainsuck plate.

    Bad luck. Fwiw I enquired with Argos about getting a replacement chainstay on a 635 p7. They wanted to do both sides, and by the time you’d added paint it really wasn’t worth it.

    It sounds a nice frame, hard to replace and well loved so no brainer to get it repaired.

    Is it the swinger dropout frame? That looks like a pretty easy repair to do (hacksaw off the old stay, file off the remains at bb and dropout then braze in a new one). The stay itself is only £15-20. If you were nearer I would have happily helped out for a box of beer (you are South Wales ish?). Unfortunately I’m wrong end of England.

    I’ve done a double stay with twin half inch tubes which gains clearance without crimping but doubt you’d convince someone else to build that 🙂

    You can always ask the manufacturer, they can only tell you no.

    You could send argos pictures for an estimate.

    If I was on a budget I would measure the chainstay and see if Ceeway or similar have a chainstay close. You could then cut out the existing chainstay and profile the new chainstay to fit, you could take it to any weld/fab place with an old hub and get them to weld it up. Getting a frame builder to do it in a jig would be better.

    Where are you based?

    Personally I would TIG weld it, or get my old man to braze it.

    Yep.

    I’ve contacted Charlie to see what he says but he’s out of the country for a while. Also, Argos didn’t answer their phone all day so I’m having to cool my heels a bit 🙂

    Appreciated. Since you seem to know what you are talking about, how feasible and/or beneficial is the plate type arrangement in the picture on the previous page?

    1x mate.

    Yeah, well that’s another few hundred quid that I am even further from having now I have to get the frame fixed. I don’t run really old 3×9 as a fashion statement!

    If I was on a budget

    Yeah I need it done right if I’m going to do it. £120 from Argos I can swallow, just about. I’ll attempt most things but not this job.

    Chainstay plate / yoke is generally to give more clearance for tyre and chainring rather than to shrug off chain suck as such (but I guess it will survive better than a thin tube). There aren’t many ready-made plates on the market – I’ve not seen any at Ceeway / Paragon / Frame supply, so tends to be a Taiwan factory thing or builders have their own made (laser cut, CNC etc). They also make the job generally more of a faff and another thing to align and mitre so will be more expensive if you can find someone willing to do one as a repair.

    I tried hand making my own plate yoke last year but it was a bit “soft” so I junked it – stumbled on this last week which was a much nicer production version of my failed hand cut attempt https://www.instagram.com/p/Bl8xGxNByZE/ . Plates need to be a decent steel so it flexes and springs back – mild steel in those dimensions just flexes and yields….

    I’ve spent 18 years singlespeed or 1x so actually forgot that chainsuck was a thing! If there is space, could just silver solder a sacrificial 1mm stainless plate on top of a new chainstay so you aren’t putting fatigue initiating gouges in the main tube (fatigue is my day job and that is how that tube failed).

    See how you get on with Charlie and Argos. I guess you are looking at rattle-can rather than an additional £160 for Argos paint. Other option is £30-£40 would get it powder coated but appreciate you might want to keep as much Salsa paint and stickers as possible.

    PM me if you are struggling – I think you helped with the Gnusmas stuff so would be nice if the forum could return a favour. I’ve not got any stays at the moment but probably need to order a few other bits from Ceeway anyway.

    fatigue initiating gouges in the main tube (fatigue is my day job and that is how that tube failed).

    So, no point in putting in a warranty claim then?

    If you get really stuck and on a budget I’m not far from you (Pontypool) and can tig weld. I’m not a builder to Mick.r’s standard though; I would clean the area up, tube inside and plug weld then weld up the crack and build the gouged area back up with weld, sand back and leave you to paint.
    Being honest if I were you I’d go to Argos for a proper job if the frame means that much to you.

    2 frames under warranty? I’d be saying seeyah and looking at a diff manufacturer.

    Why does there need to be an associated cost for 1X other than £13 for a chainring? I’ve only dropped a chain once in several thousand miles on my HT with nothing other than a narrow wide fitted.

    molgrips , what size frame? I have a 2012 Frame and forks sat doing nothing.

    Tbh i was thinking looks like that 🙂

    If it’s in warranty I’d see what they can do, could even be a batch they’ve had issues with.

    Find a motorsports shop or small machinest locally who can TIG, get em to plug n’ weld it up. Job done. Sure it’ll be a few grams heavier but hey so what!

    Cos 1×9 isn’t enough range.

    What frame? An El Mar? Mine was large but I could go medium.

    How old? How much? Tempting but like I say I don’t think I could bring myself to bin the current one.

    Premier Icon mick_r

    You wouldn’t bin it, just gives time for a more leisurely repair 🙂

    If I loved a frame as much as you love that one Molgrips, I’d be repairing it. Shirley a decent framebuilder could take off the chainstay without damaging the BB shell/rear dropout & even braze a new one in?
    My old HT has had this done without any issues. (although It’s all fillet brazed, not welded)

    That’s the plan EG, Argos cycles said they could. Current plan is to have them replace the stay and strip the frame, and paint it myself using spray.bike.

    Only thing I am now worried about is what colour to go for. I could try and re-create the same colour, and they have sparkles to apply on top – or I could try something new.

    I rather like the stone colour of the Big Brother linked to earlier in the thread. Would look great with my raw carbon fork.

    Update

    Finally took the frame into Argos a couple of weeks ago, it’s now ready! Gonna try and pick it up today.

    Given the horror stories of El Mars cracking at the crimps I had both stays done. They were confident there’d still be the same.tyre clearance, let’s see.

    I think the original paint is a candy colour? Or whatever the non american version of that is. My “golden child” el mariachi was IIRC orange paint with a brown clearcoat and golden flecks. You could probably match the colour so it looks the same from a distance but to get the same finish is a bit more involved, if youve not already stripped it then a car spraying shop might be able to match the process if they can see what was there before?

    Fingers crossed it’s just what you wanted! Any plans for chainsuck protection? If I’d seen this first time round, I’d have suggested getting bosses put in for a plate like Dekerf do/did:

    Didn’t know you could get ones like Steve T’s at the top, though.

    I think the original paint is a candy colour?

    Re paint, it was a sort of cherry red, I had assumed with metallic flakes like a car. But on closer inspection, it’s not – the base coat is sort of crinkly. I showed it to Argos, and they pointed me to their rack of sample colours, and they do basically the exact same finish in the same colour. It’s a process of many steps, and is another £200 or so.

    However, some say Argos painted finishes aren’t durable, and if it was the same as the original finish that would make sense because it wasn’t that durable. See the other ‘Is this a crack?’ thread I started. The paint had rubbed through slightly on the cable boss and started corrosion tracks under the paint.

    Since I want the frame to last I am going to powder coat it. First I’ll try spray.bike and if that turns out shite I’ll get it powder coated later. I’ve gone for dark red + lacquer which won’t be anywhere near as nice as the original but it’ll do.

    Any plans for chainsuck protection?

    I thought about soldering a plate over the outside of the tube, then I wondered how hard it would be to remove it if it was damaged – and where do I get stainless sheet from? I have some thin alu sheet so I think I will cut a little piece of that like a frame protection sticker and use some number plate fixing tape to stick it on. If it gets mashed I’ll remove and repeat.

    Can you make it out of tough plastic? The kind of stuff a bash guard is made of?

    trumpton

    I should image that tough plastic would work fine.

    Premier Icon molgrips

    Yeah it would – harder to shape though, would need heat.

    Taxi25’s link is another option. I think at one point in the past I had one though – if you set it close enough to actually keep the chain out it rubbed – wasn’t ideal.

    Got it back. May have lost a the size in clearance and will probably have to run the dropouts at their furthest back, but it looks like it’s definitely not going to break again! Lovely job!

    Premier Icon molgrips

    Yeah about 4mm gone from each side on the maximum extended dropout position; more when the dropouts are further in. There’s still about 7mm gap with a 2.3″ Racing Ralph on my 25mm rims which isn’t too bad. 2.4s would be a squeeze tho.

    I would seriously consider not trying it in the first place. Super easy to apply and gives nice coverage but had next to no resistance to chips etc, even lacquered.

    So what’s the alternative? For £30? Already spent £240 I didn’t have.

    Frame is shotblasted, I’ve got primer, paint and lacquer. If it’s ever going to work it’ll be now.

    Maybe go straight to powder coat. Give these people a ring their only a few miles from you.

    I had a kids balance bike powder coated recently and it was £65 including stripping. I’d have spent quite a bit of time stripping it myself manually – and paint / laquer would probably have cost £30 in spray cans. Thought I’d just go for the powdercoating and really glad I did – looks great!

    The benefit of doing it yourself is you have left over paint so you can touch it up when ever you want.

    There have been some great examples on here of painting your own bike.
