Re: Advice for corroded aluminium frame head tube

Excellent news Brucey, thank you! In the back of my head, I was hoping it might be normal because the welds look so nice on the outside. I still figured if the bottom hole is nicely round that the top one should be too + that melting surface seemed awfully wrong; I guess since it's where the two tub...

Re: Advice for corroded aluminium frame head tube

UPDATE: After stripping the bike down and inspecting the head tube, I found what looks like a terrible break/melt area in the top part of the head tube (one photo is the view from the bottom up showing the normal hole). I believe the break coincides with the staining on the fork steerer. Time to bur...

Re: Advice for corroded aluminium frame head tube

Thanks for the replies. Yeah, it doesn't sound good. I really have to see what it looks like under the racer and decide from there.

They just seem dirty and there is a little rust on a few of them. I think it's easier just to replace all of them rather than clean them.

Re: Advice for corroded aluminium frame head tube

Okay, thanks. I'm going to fully disassemble it over the weekend and check it out some more. Any suggestions on what to use to get more paint off? I heard stuff like steel wool can contaminate the aluminium? Also, I have never seen corrosion pits on bike frames, if someone has any photo examples it ...

Advice for corroded aluminium frame head tube

Hi, Upon careful inspection of my bike, I noticed some paint bubbling in the head tube area. I was able to get some of the paint off from where the fork attaches to the frame using just my fingernails and found white powder under it. From what I read this could not be a big deal for aluminium frames...

Re: Replacing components on bikes unused for a few years

Thanks everyone for the replies. PS, inner cables that cost 50p-£1 each are just fine, no need to spend £30. It isn't 50p for a cable Vs £30 for a cable, it's £30 for a set of outers, inners, housing ends, cable ends and so on. There are good reasons to spend more on cables, i.e. rust resistance , l...

Replacing components on bikes unused for a few years

Hi all, I'm also wondering about your opinion on what bike components should be considered for changing on a bike that hasn't been used for about 2 years. So far I know I'll be replacing all the gear and brake cables, and in the process adjusting the derailleurs. Is there a specific kind I should bu...

Re: Risks of buying old cabron frames (10-15+ years)

I can just see the purchasers face now. Like an excited child that has bitten into its first Flake bar and seen most of it crumble and fall on the floor. :roll:


HAHAH, no! I just wanted to expand on the topic. As I said, I already decided on one of the alloy Principias. :)

Risks of buying old carbon frames (10-15+ years)

Hi all, As a lot of you provided informative and useful responses to my post about old alloy frames, I thought we could discuss buying second-hand carbon frames as well. I presume these need even more caution as damages might not be visible, but if the frame is intact it could be an amazing bargain....

Re: How many spokes?

Those Dura-Ace wheels are designed for racing. Exact loading with ultralight touring depends on rider weight (and such wheels always quote a max rider weight). However I think the issues are: 1) whether it has fancy spokes which will require a large shop to source replacements (maybe even to order)...

Re: How many spokes?

I would also like to hear opinions on spoke counts on wheels. Specifically for touring purposes when travelling light (<5kg equipment). I have seen Shimano Dura Ace WH-7700 with only 16 spokes in both rear and front wheels ( https://www.roadbikereview.com/product/wheels/wheelsets/shimano/wh-7700-dur...

Re: Risks of buying old alloy-framed road bikes ( 15 years+ )

If there's anything you can say about the prinny frames it's that they were well made, part of the reason they were so expensive and why they probably went belly up is that they were really anal about QC. +1 for Principia. I have a Rexe SX (ellipse) 2003 model, bought as a new frame around 2005. I ...

Re: Risks of buying old alloy-framed road bikes ( 15 years+ )

Hi james01, I have considered it but I prefer the idea of investing an extra £50-100 to get a high-tier bike. I think that with good examination and buying from responsible owners that upgraded, this approach has a very low risk to reward ratio. Initially, I wanted to get a new Triban RC 500 for £75...

Re: Risks of buying old alloy-framed road bikes ( 15 years+ )

Yes, I am looking for a pure road bike. The bikes I'm looking at don't seem beat up at all but will try to find out more about mileage as Vorpal pointed out.
Sane reassuring replies, just what I was looking for, thanks! :)
