Triban RC500 - 2 ans en gravel (mes modifications)

Triban RC500: Two Years of Modifications

The presenter reviews changes made to a Triban RC500 bought in March 2019. By March 2021, the bike had been adapted for road riding, gravel, touring, commuting, and rougher trails. The modifications were guided mainly by comfort, easier climbing, and practicality.

Changes and upgrades

• Handlebars: One of the first changes was fitting 46 cm flared handlebars. Their extra width feels more stable on rough ground and, especially in the drops, on gravel descents. The presenter also finds they soften small vibrations.
• Tyres: After testing sizes from 28 mm to 42 mm, the presenter settled on 38 mm as a good balance of efficiency and comfort. A 42 mm tyre can fit, but it is close to the limit. Tyre pressure should be adjusted to suit the conditions.
• Wheels: The original wheelset weighed about 2.2 kg for the pair, and its tyres were difficult to remove, making roadside repairs frustrating. A replacement disc-brake wheelset, bought for €189, weighs about 1,750 g and saves roughly 500 g. The presenter chose it for practicality as well as weight reduction.
• Gearing: The cassette was changed to a larger-range option after the original gearing proved too hard on climbs. The presenter uses an 11–36 cassette, including on hilly routes in the Pyrénées-Atlantiques. The 36-tooth sprocket works despite the rear derailleur’s stated 34-tooth limit.
• Crankset and front derailleur: After the original crankset wore out, the presenter replaced its 50/34 gearing with a 46/30 crankset. Paired with the 36-tooth sprocket, the smaller chainring makes climbing easier. Because the original front derailleur was incompatible due to the chainline, a triple front derailleur with a closer chainline solved the shifting issue.
• Pedals and carrying gear: Shimano SPD 520 pedals were fitted to improve pedalling efficiency. For bikepacking, the presenter uses a frame bag and handlebar bags, although the handlebar bags tend to move around. For longer touring trips, they generally add both front and rear racks.
• Visibility and other accessories: Black reflective stickers improve visibility without standing out on the dark frame. Large front lights are used for night rides and commuting.

Closing advice

The presenter recommends tailoring changes to your own riding and replacing parts as they wear out. They estimate that the bike can still be fully equipped for under €1,000 and describe it as versatile across several types of riding.
