Since this summer, I've been using TIOGA SPYDER SADDLE with my A-bike. Getting this unconventional saddle was a bit of a gamble, so I got good condition secondhand one from eBay for £40 instead of spending £59-£79 for brand new saddle at various online shops.
Despite it's rather bad reputation, I love the saddle so far. It doesn't hurt my bottom and it's lighter than most of saddles around! The weight 140g saves me good 180g to compare to Specialized Rival's 320g. Now I want to try this saddle without Thudbuster... but I don't own solid seatpost in right length.
This saddle bends alot as we sit on, so the setting angle needs to be a little stooping forward and seatpost needs to be higher up.
