26 girardenga
« on: July 23, 2014, 11:11:06 am »
attached, i hope you'll see a photo of my new-oldie mountain bike - italian make (girardengo) - not too expensive (´┐¢70) - light-weight steel frame (smooth tubes, no seams) - shimano everything ... 18 gears, no less - hills? ha! i speet on hills!

mountain bikes seem to be the bike of choice for oldies here where i live in italy. a lot of them (the bikes, not the old geezers riding them) look like they haven't been maintained properly or even seen the light of day outside a garage or cantina, since they were wantonly discarded by their newly-licensed, car-driving kid owners, lo' those many years ago.

as they're an entirely new and modern breed of bike to me ... hip is the new retro.

presently with the mechanics to replace a cracked crankarm - so i can't eye-ball it - but i'm curious to know if 27,5 tires will fit on this frame.

anyone?

It was built for 26" wheels, so probably not.
What we've been doing with old mountain bikes lately - the ones without any suspension - is we mount high pressure, narrow tires on them.
They make decent commuters when set up like that.

interesting - how narrow? ... racing narrow or city narrow?

I assume by 27,5 you mean the "new" size 27.5".  That size is the same rim diameter as French 650B, which is 584mm diameter. The frame and cantilever brake mounts are for 559mm rims. So the brake placement is about 1.5 cm too small for those tires. Pay no attention to tire size designation except for ISO or ETRTO!  All the others seem to be designed to confuse.
