Recommended transmission
On the Aurora Gravel Rally Series, you won't be confronted with impossible climbs. However, some climbs can be long, which is why we recommend a minimum development of less than 2 metres.
Double or single platter? Either will do, but single-platter is preferable.
What type of development should I choose? We've opted for a 40-tooth mono-platter with a 10-46 cassette.
