## Questions & Answers

**Q: Will this fit a gt aggressor pro?**
A: This will  fit any standard bicycle fork.The height you adjust best for you

**Q: Anyone add this to a trek ebike? specifically an allant?**
A: I put it on my Trek Marlin 5 and it works great.  It is pretty universal so I suspect it would fit the Trek e-bike.  Be aware however that it voids and "warrantee" that you have with Trek.  Not a huge deal with my Marlin 5 but with the e-bike it could be significant.

**Q: Will this extender fit a 27.5" Villotti /Genesis by Kent?**
A: If your bike has a 1 1/8” non threaded steer tube then it will fit. I would recommend having a local bike shop install it, in case any adjustments are needed.

**Q: Will you sell me the long cap screw? I cut mine too short. I’m**
A: no i am using mine look to a hardware store
