To be fair the El Mar is steel and will be heavier and you won’t get a new one for a grand unluess it’s a special offer.
Realistically for new at £1000, you’re prob looking at the scandium On-One (Scandal) – you’ll prob get Rebas and SLX which would be a good package for a grand these days.
If it turns out the aluminium rides a little too stiff you can always swap out to a Cotic/Singular/Salsa steel frame later. I saw some real bargain El Mar frames at Triton Cycles recently.
A few years back I bought an Orange P7 which was a fantastic package. At the same time I bought a Cotic Soul frame for Cy. I sold the P7 frame for an excellent price. I ended up with the exact Cotic build I’d wanted and saved £250 on the cost of building it from scratch.
