I had a puncture at the weekend and noticed some cracking in my rim like this:

Can someone recommend a cheap-ish replacement rim?

It's for my commuter/pub bike. Tyres are 26x1.25" slicks at 60-80 psi, disc brake hub, singlespeed (not fixie). Riding is mostly road with the occasional towpath, pump track and I'd like it to be able to do the blue route at Llandgela every now and then (with different tyres, maybe :wink: )

Current rim is a Mavic XM719. It's about 6 years old and done around 5000 miles, mostly on road. I went for the XM719 because I wanted something reliable that needed virtually no maintenance and wouldn't break - it's done this job well (only needed truing once, about 2 months after I got it) but I'm disappointed that it's failed by cracking.

According to http://forums.mtbr.com/wheels-tires/mav ... 01993.html, Mavic say the XM719 shouldn't be used with disc brakes or high tyre pressures, so I don't want another XM719.

    Best thread title ever?

    Sorry I can't actually help with any advice.
    You'll not see nothing like the mighty Quin.

    Firstly, your tyre pressure is excessive... with those tyres you should run 40-60 PSI. If you do so, you will not run high pressure. There is no benefit in pumping the tyres rock hard
    That said, if you don't like Mavic, you can look at the Velocity range available at Brick Lane Bikes

    I have a lightweight Sunringle Equalizer21 rim for sale (357g), just came off my commuter....

    I wouldn't want to run less than 60psi on 1.25", I run 80psi in my 1.5" (maximum approved on the sides of both tyres which are different makes) and have done so for the last 5 years/5000 miles.

    I did a rolling resistance test by checking my speed by coasting from an almost standing start down a hill and 80 was faster than any other pressure (in 10psi decrements) down to 40psi.
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.
