Frame failure experiences

[bikeworkshop]

^ Probably had a hard life urban duty and stored outside?

Looks like a lot of rust in the BB shell. Is there a drain hole?

No drain hole.
Inadequate rust treatment.
No grease on bb thread.

We sold a few of these cinelli taiwanese steel frames new - at first you think they are good value, then when you look more closely, you get it.

It's not really had a harder life than many frames, apart from a big toptube dent from one of those
"You can break D-lock by twisting the bike" idiots.
The steel is so thick it's unlikely rust was the root cause, just low grade metal imo.
Hence the incredibly short guarantee!

Iirc these bikes were built up in the uk either by Chicken Distribution or the shop "Bristol Dropouts" (come and gone with the fixie boom) where the owner bought it.
I guess the latter as I don't think chicken would scrimp on the grease.

My main issue will be leaving adequate tyre clearance as I need to plate both Sides right at the "bulge" - double chainstay Replacement would exceed the frame's value, and he quite likes the 10 years of wear and tear

- that's for the angle grinder and wheely bin.

It is a bit shocking when you would expect something a bit better from Cinelli, but I guess anything would fail not built properly and being looked after.

Same as all that Masi crap that was built by the new brand owners.

Sort of agree. Haro had it eventuality. Sold my pre-curser gravel CX / Light tourer Masi last year - bubble rust to the top-tube and around the BB. A good 10 years old.

I look after my bikes, but sadly my sweat seemed to attack it too much too fast. For the price and the level it wasn't a bad deal, a good gruppo, some nice lug details, but I've done with this kind stuff now.

Ideally I don't want to do disposable bikes no longer - focus in our retro game of special cheap old steel for some abuse for fun, or collectable best summertime kind of thing only.

Crude but (hopefully) effective - ready to do the next 10 years

Looking at above pic

Now what can be done with this > 1949 path frame, chainring has cut into the chainstay (previous owner!) , not gone through, but deep enough to concern me. SPoke to my usual frame builder, who said if filled in by brazing it may weaken the stay. I know these old frames are tough as nails (also commented by a builder) and could well be OK, but....

Any suggestions?

I am a big fan of patching - using bicycle tubing.

Simple and effective.
But pretty it ain't.
You need to appreciate the battle scars!

(You'd also need to accommodate 2mm of material)

You can easily spread the stress around a wide area, without too much heating of the old metal.

An invisible repair here would be to replace the whole stay.

Cracking buys this week

It's about time you offered bespoke steel builds at ten grand a pop. You could even call them Gravel.

Special mid tube lug frame design. You could be a millionaire by Christmas.
