Is the Nishiki Colorado Comp good for beginners?

Yes. The upright hardtail frame, hydraulic brakes and 120 mm fork suit green and blue trail riders. Heavier or aggressive riders will outgrow the fork quickly.

Does it have a dropper post?

No. The frame is dropper-post ready with internal routing, but you have to buy and fit the post yourself.

What size tires does it take?

It comes with 27.5+ tires at 2.4 in wide. The frame and fork clear plus-size rubber, which is the main reason for the extra grip and cushioning.

Can I upgrade the fork later?

The tapered head tube accepts most aftermarket trail forks, so a fork upgrade is possible. Check axle and travel specs before buying.

Is the Nishiki Colorado Comp worth it?

For a first trail bike it is a fair package: hydraulic brakes, a 120 mm fork and a dropper-ready frame are features cheaper hardtails often skip. The trade-off is the 35.8 lb weight and a basic fork.
