Those bamboo mudguards remind me of a pair of steel mudguards with almost no wrap-around that I had (still have in the shed). The quality was good but I didn't half get a lot of stray spray - I didn't notice it when riding but certainly noticed the resultant muck on the bike afterwards (and I had a good sized home-made mudflap on the front guard). So I decided to replace them and went for something quite different - SKS longboards. They do a really good job.
