Wanted: Aventon Mataro 55cm frame or equivalent

Heartbreaking news from the bike shop this morning. They can't service my bike cos the frame is cracked. Explains the recent weird handling.

Anyways, I now am in desperate need of a replacement. Open to suggestions, but really as long as the fit is similar to the Mataro, I'd consider. I'm not exactly wedded to any brand.

I've got a complete Shorter 54cm track bike might be an option . https://www.lfgss.com/conversations/341805/#comment15130426

Might be a touch small? I'm 5'11. I could come test ride though as I'm in Acton.

At 5'11 might be on the small size for you but welcome to view your test ride.

Similarly, I've got a 54/55cm Surosa track bike built up for road available. I'm between, 5'1 and 6ft, and found that rejigging to a slightly longer stem, riser bars and a layback post gave me a nice bit of breathing space while retaining that 'nippy commuter' feel.

Ali frame, drilled Alpina carbon forks, Sugino messenger set, Shimano RS front, Quando flipflop rear with a Sturmey freewheel, 25c Conti's, some ITM and spesh bits. Don't mind chucking in a lock and lights and whatnot, as I'll be travelling for a bit soon. £210 for the next week, Woolwich Arsenal.

Thanks for the responses all, appreciated. Went with cgg's suggestion in the end.
