Rim question

I got a quote for Mavic Aksium elite 25s in chain reaction. I was told the 25mm rim would be suitable for slightly heavier rider, and the wheels are in my budget. (cant afford handbuilts) my current wheels are 622-15c wheels. Will my bike be able to take 25c rims? Im getting confused. And will I need to stick to 25mm tyres on this rim?

    I think they are trying to confuse you... 15 is an internal width of the rim, just like yours and 25 is an external diameter of the tyre they offer in the combo...

    Basically they are a pair of normal Aksium with some Mavic branded 25 mm tyres... there is no magic in that

    Keep your wheels (same width) and stick bigger tyres if that's what you are after

    I need to change the wheels to upgrade from Sora 9sp to 105 11sp. It was chain reaction I spoke to. I cant believe he would say that though with regards to the weight and the wider rim. I took it he meant a 25mm rim and that is where im getting confused, but he definitely said the rims were rider and would support weight better on this wheelset and running 23mm tyres might be an issue.

    And if you read the link there is no mention of 25 mm wide rims... which is instead the tyre size . the Rim is a 15 x 622 ETRTO, just like yours

    What you need to look more at is the spokes...for a "bomb proof" (if properly built) you will want to look at 32 spokes in a 3 cross fashion. I would also look for Brass nipples at least on the drive side of the rear wheel. You could more than likely get away with a 28 spoke from wheel 2 cross. You could go double butted spokes on the front and the non-drive side of the rear. Also, make certain that you get a wheel with "spoke prep" or similar and are "pre-tensioned" (meaning basically the wheels were pressed horisontally to let the spokes "unwind" in the seats, and then re-trued). I would also maybe look for a double eyelet rim, such as the Open4 from Mavic.


    Granted this is in the US but this is the MOST popular go-to wheel for people on their training bikes. You know it will get you home and require about nothing but riding.

    Long story short. Chain reaction confused me, along with themselves.

    The Open 4 is'nt produced in 20 years and the Open Pro is outdated for at least 10 years.
    Much better rims available now...

    Agreed about much better rims - he however stated that he is heavier. Heavier likes a higher spoke count. Higher spoke count allows lower spoke tension. Lower spoke tension allows a tad bit more comfort. Plus, a 32x is BOMB proof even on a tandem. When money is an issue the wise dollar gets spent on something that will last forever. Best I could tell, he is not looking at race wheels.

    Take a 17C rim and you can sink the pressure 1 bar which brings more comfort than any wheelconstruction.
    Agree about the spokecount, not for comfort but reliability/durability.

    Having said all that, the Mavic Aksium elite I have been told is a decent budget wheel upgrade, and should take a good battering. If I watch out for pot holes and not drop off uneven road, I should be fine until I cut some weight. I got down from 21 stone to 16 stone in a year, but I got knocked off the bike and I could not ride for longer than 20 mins without pain. Now Im better and ready to go and shift the rest off me.

    On another note, I was advised the Fulcrum Racing 5 LG would be a good option
