    Cannondale T2 frame weight; upgrades

    It being winter I am daydreaming weight weenie-type upgrades on our 2015 C-dale T2. It seems impossible to get frame weights on production bikes. There was some discussion on this bike on this forum when it was being introduced but could not find anything on definitive on weight. Wondering how it compares with Robusta, for example, or if it is at least significantly lighter than a steel Comotion. The T2 is rather beefy, plus has lateral tube, so am sure it is heavier than Robusta. The fork, in particular would seem to be one place to upgrade. Is a fatty tandem but it looks nothing like earlier versions, which are available as aftermarket and I've seen listed at 950 grams. Might take ours off and weigh it to see.
    Have the spreadsheet out and am really curious if I could come close to 30lbs with this thing without carbon wheels, though am sure it would probably be prohibitively expensive. Gates drive, cranks, wheels are also easy places to upgrade. Would rather not start replacing all the cockpit parts with carbon either.

    We picked up a 2007 Trek T2000 a couple years ago. The frame is likely a little lighter than your Cannondale. A friend has a 2011 model and our Trek is not as buff as his Cannondale. When we got the T2000 there were some obvious places where grams could be shed: stoker saddle/suspension seatpost, wheels/tires, etc. After the stock wheels started having problems we got some Spinergy wheels and put on some Michelin tires; that shaved at least 1.5 lbs. I also picked up some clearance-sale carbon bling: Easton Haven seatpost, Terry Butterfly Carbon, Pro Stem, etc. The stock weight of the bike was over 34lbs. but now is under 30lbs. When we run a disc brake in the rear the weight is slightly over 30lbs., maybe closer to 31lbs. complete with pedals, bottle cages, etc. Almost forgot, we dropped a bunch of weight by switching to a fixed stoker stem and Viper Wing bars (currently around $80 - $100 at Nashbar). That shaved at least a pound. we got the bike for $1500 so spending another $1000 on some good wheels didn't bother us. I would say we have under $3K in the bike and we're super happy. FYI, a riding buddy has an older Robusta (2005-ish model) and our Trek is a couple pounds lighter.

    I did have my eye on the suspension seatpost, a thudbuster. Stoker having none of that though. Fixed stoker stem is a nice touch. I did consider going with caliper front brake as possibility. It would defeats one of my arguments for getting the bike-ability to run 650b wheels.

    I think you could get 30lb or even under but you would be keeping the frame and not much else.

    We also have a Trek T2000, 2006 model I think, for which we also paid $1500 several years ago. It's kept in England where we use it for short rides and the occasional tour, such as a trip to Paris in 2014 along the Avenue Verte.
    I have not spent too much time trying to reduce its weight, although I have put 48-36-24 chainrings on it to help our old legs and am toying with the idea of fitting a Gates timing belt. However, I'm curious as to how you fitted a rear disc. Did your frame already have the necessary fittings? We have a drum drag brake, which weighs a ton and since I now have Spinergy wheels, I could fit a disc if the frame allowed. Yes, we also had a Bontrager hub fail and I don't have too much faith in the other one.

    We also have a 2014 T2, which I bought on impulse at a very low price for a very low mileage machine. The only mod I had to do was to convert to an extending stoker stem. It's very heavy as compared to our Macchiato and even our T2000, but it looks so good!!
    I looked at fitting a caliper front brake, but Cannondale said it would invalidate the warranty and I also found that the fork holes are not aligned, so I can't fit that brake anyway. As I had a spare pair of Spinergy TX2s, I started to fit them only to find that the front one was not set up for a disc. That was soon resolved by House of Tandems who sold me a demo with disc fitting. Now we have Spinergy with 28mm Conti 4000s. It's a very comfortable, smooth ride, but not for hills at our ages, so we won't be taking it to GTR even if the routes are flatter this year. How you would get it to even near 30lb without cutting chunks from the frame and changing the massive fork, I don't know. I'm not going to try!

    Hanging on to our custom 2003 Zona c/f tandem; it's 'almost' broken in with 45,000 on the odometer.
    Without our stuff/necessities on the the bike (tools, trunkbag, water, rack) it weighed in at 26.5 lbs; add about 4 to 5 lbs for our necessities.
    Pedal on!

    On ours the hole in the fork is for fender mount and not caliper brake. But yes, carbon fork with caliper brake is one way to cut pounds. Would require reducing headset. Between wheels, fork, belt drive, there is definitely some weight savings to be had. Whether it's worth it is another story. In fact fork replacement was in the back of my mind when I bought it as I did get a substantial discount; enough to cover fork and a few other things. I see on the other thread that BNB reports a weight of 40 ibs for their T2. Am guessing ours could be that heavy too. will have to see.

    Take a look at post #413 here:

    What's your tandem weigh?

    Our 2007 T2000 is disc-brake ready in the rear. Trek did other things to make it fairly light in 2007/08: SRAM Carbon cranksets and carbon front fork - I weighed the cranks and the crank arms were about the same weight as my X0 MTB cranks, very light. The stock rear saddle and suspension post were boat anchors. Also, the rear drop bars with adjustable stem weighed a lot. I could do some other nutty stuff to shave another pound but at this point I'm content with the bike.
