Hello and thanks for checking out this new set of Full Speed Ahead (FSA) Pro Road compact 50/34 tooth 10 or 11-Speed chainrings! These rings will come in the new "take-off" condition seen in the included photographs. This chainring set is compatible with any 5-arm 110mm BCD crank, perfect for road or tri builds. Compatible with both 10 or 11-speed drivetrains. As an added bonus the correct chainring bolts are included (a $25 value). These rings were likely pulled off their original cranks during the pandemic craziness when a lot of hoops had to be jumped through to complete builds. Perfect for the rider looking to try out a new chainring combination or to maintain your current setup. I have a small handful of these chainrings sets available, each in the same mint, new condition seen in the included photographs. Standard MSRP of $85...pick a set up here for less with FREE Standard Shipping within the USA! Expedited shipping available at additional cost. Contact me with any questions, I will do my best to answer them. Review my feedback and buy with confidence. Thanks again!
