Raleigh Team Banana Project

[Gunk]

You can put a modern BB in these. There is one on eBay for sale with a 105 5800 groupset

I saw this on the Raleigh Twenty FB page and thought of you. Someone has blinged up an R20 in the same colours.

That’s very clever

By the time this banana had come out Raleigh had switched to normal English ISO threads

The BB looks like a Raleigh threaded one. The switch to BSC/ISO was gradual and started with the high end bikes. The cheaper ones kept 26tpi threading until the late 80s.

Yep, I worked in a Raleigh 5 Star Dealer in the 70's and the change over was a real pain, when I left there the old style "sit up and beg" bikes were Raleigh threads, some still had rod brakes and locks in the forks! the "racers" had mostly changed though.

Yep my 86 Raleigh City still had cottered cranks.

It's that mostly that causes the problems.

My seat and post arrived today.

I wasn’t happy with the original, too ugly, too heavy and uncomfortable

Really pleased with the change

I Just need to tweak the adjustment, I’ll do that at the weekend.

I also weighed it, just out of curiosity, it comes in at around 11kgs which isn’t bad for a low spec pig iron bike.

10-11kg was a good rule of thumb for a pro road racing bike, once. (Surprisingly recently)

It’s the wheel swap that’s made the greatest difference. I’m now kicking myself for not weighing it before I started.

Yep, a 'Hi-tensile' tube frame might be a couple of hundred grams more but generally it's the other stuff that's heavier.

 

[rogerzilla]

Difference between a good butted steel frame and a real gaspiper is about 1 1/4 lb. You can lose that elsewhere quite easily.

Rode into Oxford this afternoon on the Banana, the seat is a huge improvement makes it feel like a modern bike (until it’s time to change gear!). I really like this bike, it just gets under your skin. I’ll keep it for a while until another project comes along.

Always sad to see a bike like this gone left to go rusty, for me I'd give it a full restoration. Looks like a great project though.
