Spokes.(5 posts)

Sep 7, 2003 11:30 AM
I've snapped a spoke on my front wheel, it's a 105 hub on a CPX 23, and I intend to get it completely re-built. I'm 185lbs, and the roads I ride can be a bit rough. What sort of gauge should I ask for ? If you offer a suggestion, please explain what the gauge means. They're my only wheels, I don't race, and just want something strong that will last.

I've allready had the rear wheel rebuilt, the guy in the shop just did it and I've no idea what he used as I wasn't wise enough to ask - but whatever he used, it wasn't up to much as it's a bit loose allready (4 weeks).

Thanks for reading.

For a front wheel, it's not necessary to rebuildMR_GRUMPY

Just have the shop replace the one broken spoke. I've never broken a front wheel spoke, and have one 18 years old. Rear wheels are a whole 'nother game.
Sounds like the rear wheel didn't have enough tension put into it. Take it back, to have it redone.
Ps. A 14 gauge spoke is 2.0mm in dia. A 15 gauge is 1.8mm in dia. A 14/15 gauge spoke is 2.0mm at either end and 1.8mm in the middle.

Mr Grumpy is right... plus - if this shop did your rear wheel and it needs work after 4 weeks you need to find another shop!!!! If you don't have an alternative consider a mail order shop like colorado cyclist or excel.

Thanks guys,

One spoke it was, not at the shop that re-built the wheel, and not the shop that re-tensioned the re-built wheel!

Third time lucky? Lets hope so.

I weigh 185 and build my own wheels, so maybe my advice will help yah some in the future.
Like other said, a wheel that has loose spokes after 4 weeks of riding- well, it wasn't built right, and the spokes are gonna start snapping down the road, its almost garunteed.
I'm not so sure your front doesn't have something wrong, but replacing the one spoke is OK the first time one snaps. If another one goes, its probably time for a re-build.

With a deeper rim like the CPX33, I'd happily run 28+ of the thinnest spokes made with alloy nips, even on rough roads. Heck, for rough roads, thin (butted) spokes are generally a MORE durable option, though you may want heavier elbos.
In general, Wheelsmith DB14's would be good up front for a high milage 28 or 32 spoke wheel for a rider your weight- they are 2.0mm at the ends, and 1.7mm in the centers. DT Supercomps are similar (2.0/1.7/1.8) but pricier (and only avaialble in black).
If you have 32 or especially 36 spokes, DT Revolutions (14g) or, or Wheelsmith XL14, are a valid choice for some weight saving. The wheel would be slightly less stiff, but that can be good for rougher roads (ride and durbility wise both). Its defiantley a good combo with a deeper rim.
My latest wheelset build (32 holes) has a lighter rims (400grams, semi aero) and Wheelsmith DB14 on the right, XL14 on the left. The front is all XL14. Its plenty strong for my weight, though obviously a hard impact could tweek it.
