Worth the weight?

I wrote last time about changing the project bike's wheelset, specifically swapping out the stock 2016 Giant SR-2 alloy clinchers with a pair of Mavic Aksium Elite hoops that I'd sourced secondhand.

Well, I haven't done the back wheel yet, as I'm waiting for a new lockring tool to be delivered, but the results are in for the front wheel. And they are, truth be told, a little underwhelming.

The weight of the front Aksium Elite, bare except for rim-tape and skewer, registered as 882g on the Kitchen Scales of Inaccuracy^TM. The Giant SR-2 front wheel, in the same bare state, clocked in at 910g. So a weight saving, sure ... but 28g isn't much. I must admit to feeling a little disappointed. Part of the reason for this is that Giant make it very hard to find weight information for anything they sell, whether that's a stem, a wheelset or a whole bike, to the extent that you're reliant on reviews to find any weight data. Unsurprisingly, I hadn't been able to find any reviews of a six year old wheelset, just this comment on Reddit that gave the weight of the front wheel as 930g.

Anyway, it's not all bad news. Since I had the wheel off and the scales out, I weighed both skewers separately too. The Mavic skewer showed as 60g, the Giant at 56g. So the Giant skewer went on with the Mavic wheel. Another 4g saved.

I also took the opportunity to fit a light weight inner tube whilst I was at it, specifically a Schwalbe Extra Light. My size of choice is the 18c-25c with 50mm Presta valve, so I can tell you that size weighs in at 76g. As for the Vavert that came out of the tyre, well, it's quite hard to fit a deflated, user tube on some kitchen scales ... the only reading I managed to get was 125g. I'm not convinced that's right but, if it was, I made more of a weight saving changing an inner tube than I did replacing a wheel...

Oh, and since prospective Giant owners have to rely on bloggers and reviewers for weight data, let me reiterate the following:

A 2016 Giant SR-2 front wheel, bare except from rim-tape and skewer, weighs 910g.

The skewer that comes with a 2016 Giant SR-2 front wheel weighs 56g.

It's unlikely, but I hope that helps someone.
