I am now working on the $899 Marin Kentfield 3. Again it has the same geo, groupset/brakes, as a $14,400 Creo SL that does not come with pedals. I can get the motors BB only an inch and a quarter in and it hits something. I have been grinding and filing for an hour. The owner has had surgery on her left foot, so I am making it a throttle ready bike. I normally don't but she is the kind of exception that proves that rule. Her foot is still in a Frankenstein velcro boot.

After hours of trial I finally got it. I wrapped a large bit with microfiber to almost 33.3 mm and then added 220 grit 3M emery paper and honed it out to a polish with a drill. It was just not one burr as usual. The entire center needed expansion. Now it it tight but goes in. I like things that are tight and go in all the way. The entire job should have been done in the time of fixing that one thing. What a PITA. I falafel. It was due tomorrow by train delivery but it will rain, so I bought an extra day to finish. Can't ride a new bike in the rain to the station. I hope you guys take satisfaction in my suffering.
