tall bars and necks
Wene I bought the--very tall--apes for one of my bikes, and by the way they can be pricey. they offered a shim set-- they are alloy and are to be used with a traditional neck. Well the leverage thats created by 20''+ is realy pushin' it--- for example--wene they are all torqued to the max. You can still make the bars flex --for and aft--That should tell you something. I used a schwinn--old school neck--but I am not sure those necks were designed to do any of this. Even if you can keep the bars in place,there is still a lot of additional stress on that neck. I'ts a math problem,and I'm not a math person but it goes like this--for every additional inch up--you are demanding more from that neck. The bike I have this set-up on is only riden by my 14 year old daughter, about 4 sundays out of the year. The rest of em' with tall bars are clamped down with bmx style necks and all is happy. Also--if one trys to go any higher than 25'' --It's almost foolish-unless everything is custom built of course!
