mogema m55 VS mogema xt

I have been asked allot lately about mogema frames for downhill. Mogeama released back than 2 models for a 5-90mm frames. They might look almost the same, but the different between them is huge. the mogema m55-90 mm was made from -- alloy which mechanical properties exceed 7000 alloy by far. aluminium 7000 series is the strongest . This model is very durable, stiff and i had a very good experience with.

The cheaper model is the xt-90 its made from from a way cheaper aluminium 6000 series. Its less stiff less durable. i have seen over the years people braking them with even non .aggressive skating style
