Hi,
I've been riding a 2005 model Campag Veloce road bike since 2007ish, spent the past year commuting on it (~100 miles/week). Wheels are Campag Vento G3 and have been great so far

Front brake felt really 'jerky' this morning on my way in, but was ok otherwise (I've been reading that this is a telltale sign - I guess now I know)... 2 minutes into the ride back home this evening, heard a massive "crack" like a gunshot and found the front rim had blown out. No idea this was coming - I weigh 55kg and take care to avoid potholes etc.

So I guess I need a new front wheel; do I need to replace both wheels, or just the front? I'm a bit worried that about the back wheel now; how can I tell if it's worn and about to break?

Any advice on what I should get? I'm looking for a wheel(s) that's not too expensive, fairly robust, will stand up to regular commuting. I'm more concerned about durability than weight, so I'm looking for a reasonable balance between price/performance

Thanks for the advice!
