I had a 25km TT champs race this weekend and lost the masters overall by 3 seconds. During the ride I dropped my chain 3x to the outside during downshifts from 14->13 and 12->11. Cost me ~45-60seconds over 3 full stops to put the chain back on. The third one was my fault 100% as I shouldn't have shifted anymore after dropping the chain 2x. Roads in rural Canterbury Nz are quite rough with chip-seal. I'll be in search of a solution to prevent chain drop for 25km club nationals in 3 weeks.
- Homemade chain keeper coming up from BB
- Wolftooth dropstop chainring
- Shorten chain to run higher tensions in 11-15t rear cassette range.
- Check the Di2 setting to see if the rear derailleur can shift slower
- Learn to slow pedal EZ before shifts to ensure chain stays on.
For info: Running a 52T sram chainring (my quarq crank), 11spd 1170 sram chain, 11-23 rear sram cassette, 11spd di2, no front derailleur or FD hanger. Installed chain line is straight on the ~13t for rear cassette from memory.
