I have a thudbuster on my curve D3 too. On one ride I covered 120km in one day from Cameron Highlands to Gua Musang (West Malaysia) with 2 other friends also on folding bikes. Like the Thudbuster so much that I got one for my Trek mtb. Your problem could be the height /reach of handle bar and saddle.
