Where this "deals" made in Spain? I will assume so because milanuncios.com is only Spanish based. I will call your trade total BS. Local second hand bike market in Spain is the stupidest shit I have ever seen. People sell you used shit more expensive than new. The typical "deal" in Spain goes something along the lines of buying something used with a 10-20% discount. Thats why I buy all my stuff new or copies from aliexpress.
Hola Fabriciom! Soy el mismo Kaboom de foromtb!
Yeah all of these were conducted in Spain, both in Madrid and in Palma de Mallorca, where I'm living now. There is a lot of overpriced crap on milanuncios but good stuff pops up every now and then, and I've never had a problem.
I bought an almost complete (full group except for cranks, chain and brake calipers) Sram Red 10v a couple of years ago for 350€. Excellent condition, no problems whatsoever.
I also bought the FSA SLK-Light crankset, 0 miles (not even a single chain mark on the rings), taken off a brand new bike, 160€.
Spare set of Speedplay cleats, brand new, 25€ including shipping.
And lots of other non-bike-related stuff.
However a lot of stuff also came from the buy/sell section of foromtb. Also mostly overpriced but again, great stuff comes up every now and then. I paid 170€ for my lightly used, great condition CAAD9 frame there.
Sure it's not like stuff's free, but there are some deals to be found.
