I wonder if we are going to get touring/trekking bikes starting to use Micro Spline hubs rather than Hyperglide at some point ? Currently you would need 142mm (through-axle) rather than 135mm (QR) spacing on your bike's rear dropouts ... but I suppose Surly is already there on that one ...


157mm is 'super boost'

There's a bit here, https://www.pinkbike.com/news/burning-q ... ndard.html there seems to be a bit of a debate between manufacturers selling people on '6mm extra is a really big improvement' and those saying 'no, you need 15mm more'

157mm Super Boost!!! Oh lordy!!! Have we not got enough "standards" already!!!??

Do you think the Shimano road groupsets will go Micro Spline thelawnet? I can certainly see the "gravel" ones going that way..:-0

PS just pressed the "report" rather than "reply" button on this post...apologies. ...finger trouble on the phone..

I don’t give a rats behind what Shimano can do anymore. Presently I can shift from a 90” gear to a 19” gear, all nineteen gears in between and upwards, in less than a second without either hand leaving the bars. The system is unerringly accurate, totally reliable and can be micro tweaked while riding. Thanks, Shimano 1989 and Paul Components.

Just realised the system utilizes the Shimano CX70 FD. Dangnamit.

well SRAM already have something similar for road. SRAM aren't as successful on road as MTB, but still it serves a purpose for Shimano, to get people to replace their 11-speed.

I find heelstrike is getting to be a problem with ever more splayed chainstays.
