Pro Bike: Laura Siddall’s Factor LS Gravel Racer

With racing pretty much on hold, Laura Siddall has been exploring - and this is the Factor LS Gravel Racer she's been doing it on

A recent convert to the format, Laura Siddall put together for us her Introductory Guide to Gravel Riding.

It only seemed fitting therefore to find out more about the bike she has been exploring the trails on close to her base in Girona, Spain. Here’s the lowdown on her Factor LS Gravel Racer.


There are so many options now for gravel bikes, but it would be rude of me if I didn’t introduce mine, the Factor LS.

I’d love to say that Factor named their gravel bike after me… L is for Laura, S is for Siddall… and whilst I will continue to think of it that way, it’s sadly not the truth.

Factory fresh!

However, like most Factor bikes there is a reason behind the name. Factor has a tradition of naming bikes honouring influential people in Rob Gitelis (Owner, Factor Bikes) life. Sadly, I’ve not quite made that influential list..yet! Ha ha!

The LS is named after Larry Shahboz, someone who for Rob lived and breathed the ethos of gravel long before it became popular, and put him on his first bike. His values of community and welcoming all were key though.

I have to say, I love my Factor LS and it’s been turning heads every time I ride (and I promise that’s not my lacking gravel skills). Here’s the spec and techy part.
