    Endurance AL frameset has the same stack and reach as the RoadLite AL .. at least in L(58) size and that can be had as a frameset for £367 as long as you don't mind not having the words Endurance stickered on it ..

    are they manufacturers make believe weights? This is the weights I have from a post where Fairwheel bikes weighed individual components from current (at the time) group sets

    Shimano Dura Ace 7900 = 2277g

    Shifters, 365.7
    Brakes, 294.8
    Crank, 744.9
    frt der, 63.9
    rr der, 164.2
    chain, 251.1
    cassette, 160.7
    cables/housing, 231.7

    If you don't include cables then it's 2045g .. and there'll be some variation due to manufacturing tolerances

    ^ yes it's carbon on Dura Ace .. Take a look at this pic it clearly shows new (on the right) and pre modification (on the left)

    What is the extra rivet point for?

    They added a second rivet point between the largest cogs and the carbon fibre center cluster.. If you look at the back of the latest cassettes and you'll see two rivets were there was one and also a different profile to the cogs to allow the extra rivet to be installed. I would guess it was done to strengthen the larger cogs connection to the carrier and prevents it from getting loose. Because although you appear to have been lucky, there are numerous threads on the web documenting these cassettes falling apart.

    The frame is great, they should have stopped there.

    This .. the wheels push it into anti !

    Worth a try then if you have a new BB ready to go and are not reliant on a successful change of bearings.

    Without teaching you to suck eggs .. Once you've got the old bearing out. Put the new bearings in the freezer overnight and warm the cups up in the oven just before you are ready to fit. This will open the press fit tolerance while the two parts are different temperatures. Also when you fit the bearing find a pipe that is the same outer diameter as the bearing. You need to be hitting on the ring race that has the tolerance fit when installing bearings. In this case the outer ring race only. If you hit the inner race .. best case you'll damage the bearings inside, worst case the bearings will give way and the inner race will come out .. which ever the bearings ruined. And support the cup on a soft wood surface which will give to protect the cup faces from damage as you hit

    The chainrings are Extralite Octaramp

    The code for bearings is usually shown on the wiper seal so if you can see that code on your existing bearings then you can check if they'll fit.

    However, do you have the tools to remove and install a press fit bearing? 'Hollow tech' type systems are single use .. You can 'bodge' it without the correct tools but you risk damaging the cups or the bearings.
