- A Shim 10 spd MTB cassette work ok with Shim 10 spd road mech?
Scratch the above.
New question and change of plan! Lol
2013 Arkose 3.
Tiagra 5700 rear mech. Short cage I’m pretty sure. Same vintage 105 shifters.
2x at front. 50t and 34t chain rings.
Now want to for a 34t-11t tiagra cassette. Currently have a 12-30.
Am I correct in thinking I need a tiagra 5701 (medium/long cage, GS) rear mech to fit that? That has a 39t max capacity which is perfect… Though it’s listed as a max low of 32t at the back I think Shimano usually go a bit beyond that…. So 34t should be do-able?
Or as scotroutes said,I could get a 9 spd nice and cheap mtb mech??
Thanks!Posted 3 months agoxraymtbMember
Looking at the same thing – getting a 10spd MTB cassette on the road/CX bike. My understanding is any MTB 9spd mech will work (inc. Altus/Acera etc.).
What is the true difference in Shimano groupset quality? Is Altus or Deore just as good at shifting (all other things being equal) as an XT but heavier? Or is there a difference in shift quality also?Posted 3 months agojuanMember
Ok I have been running a 11/42 10 speed MTB cassette on the hardtail with a 9 speed rapid rise rear mech and a flatbar tiagra 10 speed shifter (first gen).Posted 3 months ago
Back in the days 9 speed MTB and 10 speed road had the same cable ratio.
To make it work though I had to use a pilo mech hanger to lower the mech
Ok folks this gets confusing.
Old 10 speed use to work with a 9 speed mtb rear mech. I think when 105 was 10 speed this was true.
Tiagra 5700 is the same pull ratio as Shimano 11 speed so doesn’t work with 9 speed mtb. I think prior to this Tiagra had the gear cables coming out of the side of the shifter not under the bar tape like the newer 5700
But the longer cage Tiagra rear beach is officially rated to 34 teeth at the back. They make a 11 34 Tiagra block. Mine is currently shifting on a 11 36 MTB cassette just fine. As the pull ratio is the same you can use a 11 speed mech if you like. I’d go for an my block as you get an alloy spider. I’d consider a 36 as you don’t really add much to any particular great gaps.Posted 3 months agosenor jSubscriber
I have a 10 speed 105 rear mech, 5700or 5800 , can’t remeb exactly .The last rear mech I fitted was a 10 spd slx one ( labelled on box)which came instead of the 105 cassette I thought I had ordered . It works fine.Posted 3 months ago
Can’t remeber if it’s 32 or 30 but have since seen a 34 which may get a whirl.
