Kaiser, with the Pugs its the wheels that start to get weighty, the frame is not much different to my 1 x1 except its been spread apart front and rear. The tyres are big and while not seeming heavy they are certainly more so than your average tyre, I suppose they are really 2 x 29 tyres stuck together regards weight. Surly light tubes are still around 400g per tube
The large marge rims are not light by any means, you can get the LM XC rims with the holes in them so they would come up lighter.
The wheels are the expensive part of the build and thats why I snapped up the frame I have as I got a complete wheel, LM rim onto XT hub and also another LM rim, with mine. I purchased a Surly SS disc rear hub from Jelle at Singlespeed Central at a bargain price which was cheaper than I could buy an LX hub. The bottom bracket I am going with the standard ISIS as the only real alternative is the Phil Woods and its out of my budget by a long way.
There are some cheaper suppliers out there as I'm sure you'll find but if you want to know where I got stuff from just drop me a line.
As for Surly, I suppose they do as they say on the tin.
I really love riding my 1X1, easily the most enjoyable mountain bike I have ever owned. Not the lightest and probably not the quickest, but it fits like a glove, is comfortable all day, and I've never finished a ride thinking I need something else. Every ride is fun and considering I ride 75% on my own, that matters.
Same goes for my LHT and I'm hoping for the same for the Pugsley.
Each to their own as they say, long live diversity
Carlsberg dont build Singlespeeds but if they did.......they would probably look just like mine.
I've spent half my life on bikes.........the other half I wasted
