I received my Stronglight Tripleizer yesterday in the mail. The install was not so easy as turning screws, but I managed.

First off, the stock 53/39 DA 7800 crankset needed to be machined. The tabs had to be machined flat.





Then I installed the new chainrings. If anyone orders these please remember to buy a new chainring bolt set for the 74mm 3rd ring.

I then had to install one drive size BB spacer.

Next was removing a couple chain links and fine tuning the FD. The FD setup was not easy, as usual. I had to bend it a bit to get it perfect. The setup is not spot on for OE Shimano 3 speed cranksets, so it aint a simple swap.

Regretfully I have not yet test driven it. But it shifts good so far and looks great.

Here is a comparison of my previous gearing ratios and my new ratios. What a difference!

I purchased the tripleizer from here if anyone is wondering.
