    My CAADX needs some tlc ahead of the upcoming season, so going to go 1×10 on the drivetrain. Is there a clutch mech out there that will work with a tiagra STI shifter?
    If there isn’t, will a normal road mech and a narrow-wide chainring do the business in a CX race?

    I run a normal mech and a NW ring, with a Hope chainguide and it never drops a chain. For me, this is a better solution than a clutch setup.

    The only mechs that have clutches are MTB, which have a different cable pull to road STI.

    I run a 38t Superstar I/O ring, a 11-32 SLX 10 speed cassette, 105 10 speed shifters & 105 CX ear mech, get the chain short enough, but not too short. Quite a common set up in the NW league (models may vary)

    I haven’t dropped a chain yet while racing or battering around on trails.

    You can run a Shimano clutch mech with road shifters if you use a Lindarets Tanpan, but to be honest, with a short mech & chain it’s not really necessary for racing.

    No

    I’ve been using a normal road mech with a nice short chain and the B tension up for the last year and never dropped the chain (38 wolf tooth front, 11-40 rear)

    I don’t race* but ride some pretty rough trails

    Gevenalle do a 10 speed shifter that does work with an MTB clutch mech

    *well I did once, I sucked

    42 + 10spd 11-36 here, chainguide and standard rings/mech, pretty sure I’ve never dropped a chain, I really like it. If you’re racing you may want to drop the F ring size a bit, but for normal riding there’s still top end speed for road sections and I’ve not felt over geared on any rideable* xc climbs.

    *ie one I can get up on my mtb with lower gears.

    Edit – I ran a 9spd slx shadow mech originally, worked perfect, couldn’t find one when I replaced the drivechain recently, got a long cage 10spd 105 on there currently, bit clunky getting into biggest sprocket but it does work.

    Thanks all – simple road mech and a narrow wide sounds like the place to start.

    Worked for me. Now upgraded to 11sp hydros and using a tanpan with a zee rear mech and 10s 11-36, eventual plan to go to 11-40 11s.

    A NW chainring makes most difference IMO.

    My cranks bit the dust earlier this year and I was doing an event the next day so used the triple chainset and cranks off my wife’s bike -dropped the chain a couple of times (clutch mech in off position) and once with clutch on.

    I’ve yet to drop the chain using a NW chainring with clutch on or off.

    Yes.
    Use the Lindarets Wolftooth tanpan and run a shimano clutch mech. Or just a ‘road link’ to extend the cassette range on a short road mech. I’ve done both and both work.

    You can always move the cage spring to the stiffer setting on a regular shimano road mech to help as well

    whats this road link thing? does that mean I can get a range similar to an mtb cassette with a road cassette using a road shifter?

    It means you can run a mtb cassette (I’ve run 11-36 and 11-40 on a ss 105 mech) with a road mech. The advantage of the tanpan is the use of a clutch as big cassettes on short mechs is a bit slappy on high gears.

    I ran normal Shimano road mech with the cage spring on the stiffer setting and a n/w ring up front last season and had no issues at all.

    I’m just about to setup my tripster in CX race mode with 1×11. Bought some 2nd hand ultegra cranks and a 34t superstar NW chainring..
    How do you change the cage spring setting?

    My crosser gets ragged round mtb trails with NW and short cage 105 mech, not dropped a chain yet

    A rival 10 speed shifter and an x9 clutch mech will also work. Bit more spendy than changing the tension spring though
