Iīm considering a new wheelset for this season and have been looking at the Shimano XT M785 with a checked weight of 1675 g.

Since we still have two feet of snow here in Stockholm my Trek is in storage so I canīt check the weight of the stock wheels. Does anyone know or can give a good guess?

Shimano M475 hubs with Bontrager Ranger rims. Spokes unspecified.

I was hoping to shave off about 300 g on the wheels. Is this realistic?
With new tyres, tubes and a XT cassette it seems like I can lower the weight by another 550 g compared to the stock parts.

Cheers,
Andreas
