<prompt> Human: I went for a mountain bike ride at the weekend. I was on my old trusty machine i have had since i was a teenager. it cost 130 in 2002, my companions forked out 800-ish this year on their bikes. I want to keep riding with these guys, but dont want a new bike, to succumb to the temptation to buy a new bike, or for my lack of disc breaks etc to be a frequent topic of conversation. what tips do you guys have for batting this type of thing away?  <response>: If it were me I would tell them that I just adore the bike that I already have and I have no reason to buy a new one yet. Why throw away something that is still useful? Unless the thing is literally used to pieces then Im not getting rid of it. If your companions still taunt you either ignore it or choose to stop riding with them if they want to be immature.
