Carbon seatpost tube stuck in seat tube (drill it, clamp, twist?)

Bop it!

Summer hybrid cruiser geared build (need brake cable & grips)

Yes to the bar tape!

Stem and bars away from RBRBPRN

actual lol

I also built an RGR recently but I didn't like it that much. The tires dictate road use and when I ride on the road I prefer drops. So I'll sell the Concorde to a friend and got a proper hybrid instead which i picked up today.

Got some new stealth bars and thought the clamp area looked like prime doodle real estate so I dremel-ed some fun stuff on.

Exceptionally stupid idea

Bottecchia?

Yeah scoring your bars at the clamp and potentially introducing points for cracks to propagate is really sensible

Stress risers gonna raise

Yap, it's a Bottechia traveller. Couldn't find out much about it tho. There's a Bottechia 'hybrid' in the 1990 catalogue but it has a different tubing. Couldn't find another 'Hybrid' let alona a 'Traveller' in this paint scheme. The frame is from 1990 according to the seller, so I figure the purple and neon yellow is a reminescence to the adr team colours.

He'll be fine

Probably. Still a stupid idea.

Can't help myself when I see a "Twenty". Seventh this year.

Bottechia chat chat chat! olé !
nice found

Merci! I'm really stoked to have scored this. Will hopefully turn it into a proper tourer in the medium-term future. Will document the build in my cp thread. I'm a newbie to functional bikes so I appreciate any input :)

I know nothing about functional bikes mine is weird you know...

Weird but cool! Mudguards, racks, lights, bags are all unchartered territory for me, guess I'll have to read up on the fbnpna thread when the time comes.

I'll let you know if I eat shit. I know i'm not a precision laser engraving machine but there can't be much diff between this and that.

There is a world of difference. Laser etch doesn't remove any metal, it just ablates the dye from the anodising.

Oof, didn't know that's what the laser did. How about the etchings on old handlebars, like the decorations on the sides and grooves on the clamp area? In any case I'm sort of stuck with these bars so hopefully nothing happens.

Generally, they weren't etched or engraved, they were roll stamped. While less than satisfactory from a structural point of view, the fact that rolling dies forge the material into round-bottomed grooves is much better than cutting, because the stress peak is lower and it acts on a part of the material which has been work hardened.

Oh, and roll stamping is several orders of magnitude cheaper than engraving for mass production, which is the actual reason why they used that technique :)
