Oval Chainrings for GRX
Posted: Sun Aug 29, 2021 11:00 am
After last months struggle to get up some hills, I'm looking to tweak the gearing on my gravel bike. I'm currently running bog standard GRX, with 1x 42T chainring and a 11-42T XT cassette, which is great for my local multi-surface riding, although I'm always hunting for the correct gear if I stick to the road. I was thinking of just replacing the chainring with a 38T Wolf Tooth Elliptical 110 BCD Asymmetric 4 Bolt for Shimano GRX, but I'm wondering if that'll be enough to get me round the Moors 100 and especially the BB200. Alternative options appear thin on the ground, with just the Garbaruk GRX Oval that I can find, unless I want to replace the entire crankset and get a Rotor. The Garbaruk chainring is substantially cheaper than the Woolf Tooth one, but as it's made to order, it comes with a bit of a lead time.
If I wanted to approach this from a slightly different angle though, so that I can stay with a larger front chainring and not effect road performance too much. I could instead get the replacement Garbaruk rear derailleur cage, jockey wheels and a bigger rear cassette. Although the jumps in the cogs are slightly different to the XT one, especially five and six, which I find myself in quite a bit.
Shimano - 11-13-15-17-19-21-24-28-32-37-42
Garbaruk - 11-13-15-17-20-24-28-32-36-42-[46|48|50]
Has anyone used any of the Garbaruk stuff...?
Or does anyone know of any other replacement chainrings for GRX...?
