EN521’s- are they easy to ghetto then?
I’m a fan of the BMX tube method myself but I’ve not actually done the EN521 specifically I only suggested it as it’s a pretty good value rim
I have done it on the following:
Mavic EX721 (D521)
Mavic EX729 (D321) x3
Mavic Crossland (actually a UST rim but previous stupid owner had bolloxed the in moulded rimstrip and drilled out the valve hole???!!? Ghetto fix worked and is still working)
DMR DeeVee 24″
Tioga Dh 24″ (Both 24″ tubeless conversions worked, but it’s worth noting the tires were very, very pourus and took a few goes to seal up…)
Sun Rhynolite (Pinned version too believe it or not, and it’s still working fine)
You can do it to pretty much any rim in my experience, the real key is sealant and tire choices, it’s not worth spunking silly money on a rim for three extra letters and 100g more weight (IMO of course)…
