It's one of the 700C forks with 25 mm travel. The Silk Path hybrids also have 25 mm travel. I have four Silk Road frames here which all have only 15 mm travel I think. I didn't go back and check but I think the Polish seller had 3 different tools at one point. The tool I got was right except too tall to fit in the gap. Hoping it works on the F500 I need to service.
