    Yes, my rigid Marin has this on an LX HT2 chainset. Its kinda of a winter hack and doubles as a road bike (of sorts). 48t for me works well.
    Speed offroad is nothing remarkable (fully rigid innit) and on the road, I’ve done about 45ish, I think.

    Bout the same as him ^ prob 45ish but that’s down hill, obvs.

    Single ring on the roadie type thing, 1 x 9, 11-34. I’m guessing you’re talking mtb? This is 700c and fat wheels, so gearing will work out higher than 26″ wheels

    I’m not strong enough to spin out 48T x 11 on the flat, put it that way!

    I have a double setup with a 50t on 2 of my bikes? 😉 I tend to get a bit worryful around 40mph though. Especially on the ploughed roads round ‘ere

    Haha! But none of u guys use triple chainset though?.. Ye im talkin mtb #gianttrance looking to top my 52mph top end down fast trail this summer as spinning out with the 44t but wondered as need to move front mech up to miss the 48t monster would shifting up & down to middle ring be affected?

    32 – 48 is a hell of a jump and a 22-32-48 is a massive range for a rear mech to take up the slack. 48 will hook up on more stuff too.

    Unless you’re going to buy a skinsuit and start riding down ski slopes I’d be happy with your 52mph and leave your gearing alone.

    Mmmmm indeed DONK is talking sense…i guess maybe a 46t would make more sense but is there such a ring to fit my shimano 4 bolt chainset?..yes 52 is fast but when it comes to defending koms anything is possible ha!!! ….u can call me guy #lad

    How many times a ride do you max your 44? at those speeds you are better off changing your position to get more aero, which really isn’t the done thing on an mtb. Want to go really fast? TT bike with 56-11 down the steepest hill you can find. Best of British to you.

    Hashtags? Really? Oh yeah, half term.

    Ahahahaha!!! #hellyeah #hashtagking ye theres only one segment where 52 is acheivable #crestarun but wanted a tad faster this year… Maybe i just shave me side burns off instead? #aero

    Commuter kona kula has 48/36/26 triple – you’ll need to raise the front mech up to clear the chainring & ideally increase the chain length too (I didn’t & have inadvertently gone big to big one more than one occasion that results in complete drive train lock up :oops:)

    Dickyboy yes all this is sounding a bit negative…i just have to spin faster in top gear ….cant be losing the fastest kom in our area!!!

    Yep, got a 48t big ring on my MTB although I run 24t, 36t, 48t with 11-36t on the back.

    I’ve still got a lowish bottom gear 24 – 11 for them steep climbs & a gert big 11 – 48 for the downhill blasts.

    As the others have said you’ll get around 45mph-ish depending on the size of yer kahunas 😀

    almost sure its what i got on my hardtail, which used to be a fully rigid commuter.
    can have it in any gear combinations without lock up.

    mine only locked up because I didn’t increase the chain length when I went to 48t & went big to big by mistake

    How about one legged spinning intervals to build up your cadence and smooth put your pedal strokes?

    48,36,28 with an 11-32 cassette (9 speed)on my rigid mtb.Chainset was originally a 48/38/28 but the Deore front mech couldn’t shift between the top 2 chainrings so I changed the middle ring to a 36.

    Do hashtags work in this forum then?

    Oh and my 48t is on a triple. 22/36/38 + 11-32 cassette. Its all good.

    I’m pretty sure that I used to have an Octalink Deore chainset that went 26, 36,48. I think that the 26, 36, 48 pattern kept the same tooth difference as a 22, 32, 44 allowing a standard derailleur to work with either arrangement; I’d guess that if you went 22, 32 ,48 you might have issues.

    This sounds serious Giantx4
    Its not really about whether your ring is big enough…

    but you had better have a word with the Duckman to put some catch fencing in his paddock at the bottom of the run in case it all goes Pete Tong.
