Restoring an old bike

[User16625]

I am going to attempt to restore an old bike. I already purchased some tools and parts and I will continue to buy other stuff I need. Could do with a bit of advice however. On the old road bike I have shimano 105 rear mech and probably same for the shifters (havent checked these yet). Would I be able to replace these with shimano tiagra spec parts? The rear mech and cassette is 10 speed, will any shimano 10 speeds work? Any compatibility issues I need to be aware of? I will also be replacing the sprockets.
I also tried removing the unbelievably rusty chain with a chain tool but failed. I assume the pins have seized and I cannot apply enough force to push them out. Whats the best way of removing such a chain? I will try brute force tomorrow.

I always use a junior hacksaw if the chain is dead, very little effort required and quick too!

Hi,

I wouldn't upgrade the mechs and shifters unless I had to.

Seriously flexing a section of chain should loosen
it enough for a chain tool to work I'd imagine.

rgds, sreten.

105 was a pretty good Shimano group, excellent, I would say. Replace chain and cables, and whatever else needs replacing.

Got the chain off but it needed a hammer and chisel. It wasnt just rusty, it was literally like something from the Titanic. Anyway the main purpose of restoring this bike is because I want to learn to do things myself and I am willing to spend some money. I will also use it as a run-a-round. Im considering chunkier tyres for it. Are 700*28 able to fit onto 25 rims? I would also be concerned if the forks could accommodate the extra width.

As for compatibility would the following be OK?

I only need the right hand one as I intend to keep the triple chain ring shifter.

Medium option as I have a triple. Would I be correct in assuming that "30 tooth max, 25 tooth min low sprocket compatible" means its not suitable for a 11-23 cassette but would be suitable for a 11-28 cassette? Basically does it refer to the largest sprocket on a cassette?

12-28 option. To replace an old (about 2006 or 7) 105 cassette. Are there likely compatibility issues with different shimano cassettes (of the same speed) and shimano freehub bodies?

The 170 option as its the same length crank as my old one. I did intend to keep my old crank but cant seem to find a triple set without the crank. The 130 BCD is also the same as my original crank.

Seems cheap, worth getting 105?

These are what I am likely to get. These are to be fitted to a SCR1.0 frame.

The chainset you have picked needs a Hollow tech II bottom bracket.....you will need a specific tool to fit it and will need to ensure the BB is faced.

28 tyres will fit but some are tighter than others and you can risk tyres blowing off the rim with a narrow rim. Tighter fits Ive found in 28 size are Vittoria and Bontrager. Avoid Schwalbe, they seem floppy, plenty of reports about them not fitting rims.

Ive just stuck a Tiagra 10 speed cassette on a 105 rigged bike - no issues. I did read about some issues on the freehub bodies with older stuff - worth looking at

I think you are correct in going for the medium option on the rear mech and cant see an issue with it working on your triple.

Hi,

Regarding tyres fit the fattest that will fit for a runaround. Usually the chainstay area
is more a problem than the forks for tyre width, also don't forget about mudguards.

Unless the rims are very narrow 28mm tyres are unlikely to be a problem.
I like Schwalble's basic tyres, and have had had no problem fitting them.
Nothing floppy about them, if you don't like thin sidewalls, don't choose
them, plenty of other Shwalbe tyres with tougher sidewalls.

Though the Marathon Plus is an infamously hard to fit tyre and has
spawned a relatively cult "zen and the art of tyre fitting" video :

My first thought would be the condition of the frame. Is it steel or aluminium?

Its aluminium. Frame seems to be in perfect condition. Just to update, I finally finished it and have been commuting to work on it. Brakes a bit spongy but easily capable of doing stoppies or skidding. I got new wheels (£200 the cheapest I could get quickly) and will stick with the 700/23s that came with them for now.

Most of the Shimano 8 speed mechs are compatible with shifters upto 10 speed. The only ones that were not was the Dura Ace 8 speed (which I have) and you can't run the mech with any other shifter as it has a separate pull ration (can be modified though).
