Spend money to solve specific problems.
What are looking to upgrade?
- Your fit? (bigger/smaller frame)
- Aerodynamics? (lower head tube, aero tubing)
- Strength? (stiffer rear triangle)
- Handling? (angles, offsets)
- Features? (integrated chain tensioners, longer dropouts)
- Color?
It's cool to simply want something different. Trust me. That fuels most of my equipment purchases

Even average or small riders can have seatpost issues. I recall helping a smaller masters woman with her Serenity seatpost clamp issues at TTown one afternoon. One of the average sized riders at DLV broke several Specialized saddles one season. He loved the fit of the saddle. He'd break one every 2 weeks or so and kept doing a warranty swap until he got tired of going back to the shop to do so. He also had issues with his 2009 or 2010 Fuji Track Pro seatpost topper slipping and tilting.
When you hit a bump in a track, all of your weight can be multiplied if your weight is all on your butt (as opposed to some being on the pedals).
The DF4 has a known issue with the dropouts spreading. I saw a bike with that issue last weekend in person.
