Apologies if this is the wrong type of question to ask here, but I was just wondering if anyone knows what particular wheel set comes with this Trek 1.5 2013 bike. I'm pretty sure this is the one I currently own, but other than the fact they are Bontrager I can't figure out what specific ones they are. I recently was hit by a car on my bike and (thankfully) the only damage is to the front wheelset, so I was looking to find out the weight so that I can replace them appropriately.
According to Trek's website :
Wheels: Alloy hubs w/Bontrager Approved alloy rims
And according to Bikeradar's website :
Front Wheel Weight: 1370g
Rear Wheel Weight: 1970g
I fear that you won't be able to replace the wheel with exactly the same thing since they seem to be generic wheels built for this bike. You can try the dealer you bought them from, they might have a replacement available or you can look for a different set elsewhere. In that price category you might have to buy a set (front+rear wheel) thought, but at least that means they will match.
It's a fairly generic, machine built wheelset with Bontrager branding. They're almost certainly OEM which means you won't be able to by a replacement set. Most likely Alex or similar rims. As you noticed, they're not the lightest wheels out there. A set such as this would typically retail for well under $300. The Shimano R501 or Mavic Aksium One are both good replacement wheels to look at in this price range. Either would be a nice upgrade without breaking the bank. There are some fantastic deals to be had on wheels these days.
