It works perfectly, even though it has been stationary for about 4 years. No mechanical issues. Never crashed or involved in an accident. It is currently fitted with Mavic Krysium wheels with a carbon rear hub. The original Oval wheels with carbon profile will be delivered at no extra cost, together with and in addition to the ones currently fitted. One Oval wheel was noisy, perhaps due to a failing nipple, which is why they were replaced.
