Haibike, RC29. 38T chain ring to 11-36T rear block
I thought I check the chain last week, 10 weeks old and 1500 miles of commuting all weather since mid January. Few hundred miles in the mud too.
Regularly lubricated every couple of days or so.
Chain measured with a vernier. Almost to the thou, 1 % elongation.
Fitted new Shimano 105 chain with the required additional links to lengthen.
Worked a treat on all rear sprockets except the two smallest, jumped like mad. To be expected as these two are used 90 % of the time.
Rear block changed and all is well. Toolbox filled with 1/2 dozen, very well priced 105 chains.
I plan to change at 0.5% elongation in the future and save the block.
Remains to be seen, now that the weather is improving how often that will be.
