Specialized Demo Expert Mountain Bike 2023 - Downhill Full Suspension MTB
- The Demo Expert M5 alloy frame is fully optimized to take advantage of the traction benefits of a 29-inch front wheel and the increased manueverability of a 27.5-inch rear wheel while maintaiining the ability to change your rear wheel size to 29-inch to suit different terrain and riding styles with an adjustable rear end that ensures chainstay length and bottom-bracket height stay dialed no matter the hoop size.
- The Rockshox Super Deluxe Select DH coil shock may be heavy on adjectives, but it’s even heavier on performance, offering external low speed compression and rebound adjustment while the Trunnion mount offers extra bushing overlap for increased durability.
Occasionally, without notice, manufacturers change product design and/or specifications.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
