Rone69 Posted November 11 Posted November 11 Hi to all! I am trying to find the measures of the reach of various manufacturers' shifters, in the latest versions 10s/11s/12s, disc brakes or rim brakes, mechanical or electronic, unfortunately I have not found any data on the matter. Does any of you have any reliable data? Since I'm looking to move from Ultegra R8000 mechanic with rim brakes to Ultegra Di2 12v disc (R8100), there is anyone who know which is the difference in length to the "base of the hoods" , I'm tryng to understand if I have to buy shorter stem, is there anyone who can help me?
splat Posted November 11 Posted November 11 Don't change your stem, but rather look at the reach of your handle bars. Older bars were set at about 100mm Newer bars are about 80mm or so to compensate for the longer hoods of disc brakes DieselnDust and Rone69 2

J Wakefield Posted November 12 Posted November 12 (edited) Hoods do change and have. Example the new SRAM is 5mm longer than previous and shimano from Di2 11 to 12 is also longer at 4m. the difference of 8000 to di2 you asked is 8mm in length Edited November 12 by J Wakefield splat, Jbr and DieselnDust 3
SSCC Posted November 12 Posted November 12 10 hours ago, Bike Dewing said: Can change your stem just dont go shorter than 90.. It really depends on the bike. Many modern geo gravel bikes come with 70 or 80mm stems. The bike bike radar voted as best road bike a year or two ago comes with an 80mm stem in a size large. Head tube angle, reach, fork off set all play a role. Bike Dewing 1

Look, my opinion there is based of bike fitter james videos and i have actually installed an 80mm stem on my gravel/allroad bike.. the front end does get a lot twitchier bellow 90.. i did not feel comfortable with it.. went back to 90 after two shortish rides

Maybe the battery he uses in his drill but thats about it NotSoBigBen, Bike Dewing, SSCC and 3 others 1 5

Gravel terrain maybe a twitchier front end can be beneficial for navigating tougher more technical sections.. that would make sense to me.. buuut im not that confident enough at my skill level.. got the 80 stem in the cupboard.. maybe again one day🤦♂️🤣

I would suggest looking at changing meds from crazy pills to Ritalin cause all I said as a general is not suggesting listening to BFJ. Unreal.

Not everyone on Bikehub is an armchair expert, some have real world experience too. You're working off a sample size of one, I guarantee you that John has a few more reference points.

I went from 110mm to 80mm stem and at the same time went from 440mm to 420mm bars on my road bike I cant say I feel the twitchiness you describe. Bike Dewing 1

I have no idea who he is.. and until he defends his claim that james the bike fitter is rubbish i dont really care who he is.. tell me why.. and we can talk🤷🏼♂️ other than that i am just sharing my experience Edited November 12 by Bike Dewing Chadvdw67 1
