    Hi, I have a 26 giant talon 2. Xcm 100 suntaur fork. Medium frame.

    Can I upgrade the wheel size to 27.5 and if so what do I need.

    Thanks in advance.

    Probably not.

    But if...
    - 27 wheel fits in rear between chainstays
    - 27 wheel fits in fork
    - You don't mind higher bottom bracket and front end which would change handling of bike

    you could give it a go :)

    I only bought it recently for cheap, I seen deore and aluminium so I didn't think about the wheels till the next day. So I am New to mtb(noob mistake) , planning on doing mostly fire roads. And maybe a duathlon down the line.

    Ride it and have fun 😄 Maybe not best bike for duatholon. But grand for fireroads and you might be tempted by some singletrack.

    What's wrong with the 26" wheels?

    Just reading they are not good for long spins.

    Has anyone has done a long spin 25+ miles on a 26?

    That's what I hope to do down the line. Cross training to supplement the running.I Enjoy the mountains.

    I've done up to 130 km (80 miles) on a 26 inch bike.

    The extra inch of diameter won't make any difference, you could put some faster rolling tyres on for distance.

    Back in the day, I did the Maracycle (Dublin-Belfast, Belfast-Dublin) on a 26" mountain bike.
    More recently, I've done The Cooley Thriller a few times on 26"s

    very hard to do it due to bike geometry

    also, "The extra inch of diameter won't make any difference" .... dude...

    I've done plenty of road and off road miles on a 26, you 'll be grand, just learn the basic skills, particularly off road, and before you know it, you 'll be spending a couple of grand on a full Suss enduro, and looking for new ways to kill yourself. Best of luck with it

    My brother in-law did the WW200 on a 26" hard-tail, took him a bit over 12 hours so maybe not the fastest way of doing it.

    Did Dub-Athlone-Dub and Galway-Dublin on 26” MTB with slicks. It’s not a problem, just slower!

    Changing to 27” wheels, even if possible, is pointless and maybe counter productive.

    on the road? i can't see it making as much difference on the road as it would off-road - but it seems that off-road, there's a 2.4% difference between 26" and 29", so probably about a 1%-1.5% difference for 27.5"?

    I know lads who have won the Cooley on a 26",I got a 6th myself.I've also got a silver at the XC Nationals on a 26er,nothing wrong with them at all.If youre fit you'll do well on any size wheel,if youre unfit then a 650b or 29er wont make you fit and brilliant!!

    Once did 153km on a 26er...

    Is the headtube on the frame tapered or not?

    Very,very few 650b forks are straighter steerer without spending silly money.

    We rarely know who's who on the internet. Disregarding someone's opinion, especially without providing a plausible alternative, can make you sound foolish to some ears.

    BTW, would you say that 27.5" and 2" tyres roll better than 26" and 2.4"?

    While I have ye here lads. When I put the chain on the big cog it rubs off the front derailer (inside) It's an alivio derailer. . Everything else seems to be fine. Looking forward to taking it out. I guess if I have to work harder on a 26 as I'll get more physical benefits. Pic attached re derailer. Do I just tighten one of those 2 screws or it is something else.
