TREK EMONDA ALR 5 SIZE-54

A Trek Émonda ALR 5 size 54 is generally suitable for riders between 168 - 174 cm (5'6" - 5'9") tall, according to Trek's official size chart. However, individual fit depends on proportions (torso/arm length), so consider sizing down if you have shorter limbs or up if you have a longer torso; a test ride is highly recommended to confirm comfort and proper reach. 

Expert and User Opinions on Fit

While size charts provide a general guideline, individual body proportions (like arm and leg length) can influence the ideal fit. 

• Some users around the 5'10" (178cm) height found the 54cm "just right" depending on their specific body proportions.

• One reviewer on 99spokes noted that a 56 cm frame fit them better than a 54 cm because they had long arms and a long inseam, despite being 172 cm tall (which is in the 52 cm range). This highlights that personal fit preferences can vary. 

For the most accurate fit, it is recommended to consult with a bike fitting expert at a local retailer.
