Wheel swapping

[gambatte]

Right, I've got 2 bikes. Both roadies.
1 - the commuter B'Twin Sport, about 5(?) year old, fitted out with panniers etc. 8spd cassette
2 - the new 'sunday best' B'Twin Triban 5, 9 speed cassette

I can't see any wear indicator on No1s wheels, so I'm figureing they're about ready for replacement?
I initially thought about getting a straight replacement. Then the synapses started triggering.
When I got the Triban, the general comment was "Nice, but the first upgrade you'll want is the wheels"
So I'm thinking. New wheels for the triban. Move the wheels from the Triban to the commuter. Obviously cassette to stay with the bike, not the wheels.

Is it as easy as it sounds or am I likely to encounter some problems with wheel/cassettes etc?

You just need to make sure the wheel hubs are compatible with the cassettes. Since both bikes are B'Twin they probably use the same manufacturer for their components. I think it's Shimano for the Triban?

If both cassettes are Shimano, all you need to do is make sure your new wheels have Shimano hubs suitable for 8/9/10 speed, and changing the cassettes over should be quite straightforward.

Re the wear - I don't know the rim or original thickness but on good road wheels you can try the following.

Put the edge of a ruler across the rim at right angles. Between them you should see some daylight. If you can poke the corner of a page from a sunday magazine through that gap then the rim is worn but ok. If you can fold the paper in two and still poke it through then it's borderline. Anymore and I'd be looking for a new rim/wheel.

Basically the rim becomes so thin it reaches the point where the pressure inside is greater it can cope with and can go 'pop' in a very unpleasant way.

Better still buy a proper rim gauge. Oh no I hear you cry - not another expensive tool ?
Well not that bad actually, considering how much it can save you in getting the maximum wear out of your rims without compromising safety.

1 mm is generally to be a good threshold for replacement.

Thanks for the responses.
Got a few more questions, but they're probably better in a new thread

have you checked that the dropouts are both 130mm? not a deal breaker but worth knowing if you need to add a spacer.

 

[gambatte]

Checked the dropouts. Both 130mm. Although mi digi-vernier gave me a minor heart attack. Due to a dodgy battery it reset itself with zero at -5. Meant that I initially had dropouts of 130 & 125....
There was a bit of headscratching as according to one online source 126 is/was a standard for 7 speed?
Anyway, both 130mm
I had a bit of a google after which I decided to change my route home, to visit a local dealer I've not been to before. Planet-X
Bit late now to cut a long story short, but the upshot is I am now in possession of a pair of Planet-X AL30 wheels, in white... although the website only seems to mention black or silver?

Productive evening.All wheels swapped through. 4 tyre/tubes changed. 2 cassettes swapped over. 2 pie plates dumped.

Just ordered one.

I've seen a mechanic use a small block of aluminium against the rim to check how concave it was, but 1) I wouldn't know what they're called or where to get one and 2) I don't have the skill or experience to decide if the wear is acceptable.

Thanks.
