Difference between Geoid 500 Crankset and Magene PES505 Crankset
1. The Senicx PR3 crankarms are slightly more outwards curved, while the Magene PES505 are straight and run diagonal between spindle and pedal eye. I always had issue running a 105 Di2 or GRX 12s Di2 FD, because it was rubbing against the driveside Magene arm in the bigring and high gears. Only solve was to use an Ultegra Di2 FD. With the Senicx there is way more room.
2. The Senicx PR3 Crankset that comes with the Geoid 500 has about 3mm shorter chainline than the Magene PES505! I now have the issue that my 34 inner ring is only 1 mm away from the chainstay. With the Magene arms I has about 4 mm of space to the frame.
Tomorrow I'll try to see if the Geoid Spider has a different chainline from the PES505. But I suspect not.
Did you Check the spider? Are geoid and pes505 spiders identical concerning Chainline?
