The Thar 29er saddle delivers just this, alleviating any issues associated with not being able to get your saddle far enough forward on a 29er. It even comes with an interchangeable tension system that allows the rider to customise their degree of shell flex. This tension system comes in two levels: soft & hard. The image below demonstrates how the Thar compares with the Tundra when mounted on a 29er MTB. The Thar is on the bike top-left, while the Tundra is on the bike bottom right.
