Direct Line Between Bb


trialin

Recommended Posts

Any one suffers from low back pain? Please say yes~~~ :rolleyes:

Somehow I've tested longer stem setting on 24" last week that makes nearly 81cm length by the direct line between bar-center to buttom bracket, then my low back started to pain after a very bunny hop and flat tire came with.

Low back pains really suffer... :$ :blink::sick:

That's why I start to think how long will be proper of BB-line(bar center to BB) to fit my height(5'9"), by past riding I found 80cm is the best length for my height on pure trial, but urban 24", I just dunt know. lol

Come on, share me your setting and how you feel about it, any advice to me kindda low-back-hurt-people could be much helpful :)

I dunt get how will be the best position of my bar for me.

My ride is Echo Urban 24 2010, ECHO TR bar and stem switched for 90mm/5deg & 110mm/20deg.

Any recommendation, thx nice guy :D

sounds like you need to have a rest for a few days and let your back heal. If your back pain is coming while you are riding then look at your riding position. are you hunched over a lot? Because that will give you lots of aching in your back.

it's too late.. ;)

now my lumbar is aching by twisting to the right, any stretch or even walking faster.... it sucks :sick:

so I plan to change stem from custom 110mm/20deg to ECHO TR stem 100mm/35deg, it should immensely shorten the bar distance while standing on pedals.

Sincerely, bike geo is much important than you think. go check good boy~ :P
