**Thomson DP-E105 Elite Dropper Seatpost (27.2mm, 125mm, EUC): Pros, Cons, and Recommendation**

1. **Durability:** Thomson is known for its high-quality products, and the DP-E105 is no exception. It is engineered with a 7000 series aluminum and is anodized to provide a strong and durable product.

2. **Reliable Performance:** The Thomson seatpost offers consistent performance, thanks to its sealed hydraulic cartridge and mechanical lock. This ensures smooth actuation and secure positioning of the saddle.

3. **Adjustability:** With a travel of 125mm, it offers a decent range of adjustability for many riders. The cable actuated design allows for easy adjustment of saddle height.

4. **Aesthetics:** The clean, minimalist design of the Thomson DP-E105 will appeal to many riders who value a sleek and uncluttered look on their bike.

1. **Price:** Thomson products are often more expensive than many of their competitors. The DP-E105 is no exception, and its price may be a deterrent for some potential buyers.

2. **Cable Operation:** While the cable actuated design is simple and reliable, it requires more maintenance compared to internally routed or electronic dropper posts.

3. **Sizing:** The DP-E105 only comes in a 27.2mm diameter, which may not be compatible with all frames.

The Thomson DP-E105 Elite Dropper Seatpost offers excellent durability, reliable performance, and adjustability. However, its high price and sizing limitations are potential drawbacks. If you are looking for a high-quality dropper post and are willing to pay a premium for it, then the Thomson DP-E105 could be a great choice. If budget or sizing is a concern, there may be other dropper posts that better suit your needs.

If you are looking for a reliable, durable dropper post and have the budget for it, the Thomson DP-E105 Elite Dropper Seatpost is a solid choice. If you are on a tighter budget or require a different diameter, you may want to consider other options in the market. Always ensure compatibility with your bike frame before making a purchase.

Details:

Includes the basically useless IMHO Thomson dropper lever, I ran it with a Shaman lever. Bought new from Universal Cycles on 8/4/19 for building up my Santa Cruz Highball carbon V3. Model number DP-E105. Great for putting on your gravel bike if you don't have an option internally routing, and can fit the 125mm travel.

There Wren't a lot of good 27.2mm dropper options back then, and I went with the externally routed option so could switch to rigid post pretty easily. Low miles since I ride my full suspension bikes most of the time in CO still works great.
