rims from hell (ambrosio 19 additional elite)

[ad_1]

what’s it about these rims (ambrosio 19 additional elite) that make ’em so rattling troublesome to mount tires?

i got here throughout these once more this week for less than the second time when a good friend requested me to rebuild a few his bikes. the primary time, years in the past, i naively purchased a set off craigslist for a ’84 fuji i used to be constructing. i attempted to mount kevlar tires on them and knew i had lastly met my match. it was an insane activity. so i made a decision to purchase a var tire lever only for these rims. it labored. when i bought the fuji, i bought the var device with it. i’ve by no means wanted a devoted tire mounting device till now when these rims re-entered my life.

i advised my buddy that i would not be altering the tires on this rebuild. however after i had achieved lots of work on the bike, i observed the continental tire labels weren’t centered over the valve gap, and the rear tire was mounted backwards. this began to essentially bug me, so i made a decision to attempt to reposition them. it was actually laborious to take action with simply two plastic tire levers, however i used to be lastly capable of mount the tires accurately … and with out breaking a lever. whew!

velobase says the erd is 614. is that the first difficulty inflicting the mounting headache with these rims?

one velobase remark: “I simply picked up a 1984 Trek. It had these rims on them with 27×1 1/4 tires. Possibly that solves the issue I preserve listening to about making an attempt to get 700c tires on and off.”

that remark jogs my memory when one other good friend had a set of those, and he would not imagine me when i advised him his rims weren’t 27″ in dimension. he discovered it unimaginable to imagine they had been 700c because of tires being so troublesome to mount.

i feel metal beaded tires are simpler to mount on these, slightly than kevlar. is that your expertise too?
