I’ll be buying a towbar rack in the next couple of weeks, both my bikes are carbon, and the atera genio Pro has (IMO) the best frame clamping system, with a ratchet strap that goes around the entire frame.
However, the Buzzrack E-scorpion looks better in every other respect – price, ability to take different wheelbase bikes, but it has the clamp type holders which could be OK but I think I’d prefer the atera type.
You can buy the atera frame clamps separately, so if anyone who owns either an Atera strada with these clamps and/or a buzzrack E-scorpion could measure the diameter of the bar the frame clamps attach too, that would extremely helpful!
I’m hoping the buzzrack bar diameter is the same or slightly smaller than the atera which will mean both will fit. The buzzrack E-scorpion + a couple of atera clamps is still way cheaper than the genio Pro.
Have a Buzzrack Scorpion which is great, so easy to use, clamps carbon frames very nicely.
It replaced an atera Strada which I hated – did not hold the towball securely and was a right faff to set up. Mine did require that you thread bars through the bike frames to clamp additional bikes which was a nightmare. I gues you could avaoid thisissue with a different design
I have an Atera Strada Evo (I think) but the tube is oval so the arm fits around a rubber insert. The strap does wear with weekly usage, so I have to lock the strap with the key, otherwise it lets go at inopportune moments.
Also the Atera has a mechanism that prevents it functioning unless the arm is secured to the carrier tube..
I used to have a Buzzrack Quattro and the clamps were fine with carbon frames. Really held the bike firm no problem. You’d have to be trying really hard to cause any damage to the frame. the good thing about the clamps are that you can have them open and load bikes up with the clamps open and once you’ve faffed about a bit mountain all the bikes and done all the jiggling and fine tuning that is inevitable then tighten up the clamps.
Cheers, I think I’ll order the Buzzrack E-scorpion and then see what the clamps are like – at least I have the option to fit the atera clamps if I want.
