The cyclocross season is now under way and Cerv\u00e9lo<\/a> has released the R5-CX. Cerv\u00e9lo says the bike was designed specifically for Team Jumbo-Visma riders Marianne Vos and Wout Van Aert, who hold 10 cyclocross world championship titles between them.<\/p>\n

The R5-CX is currently only available to the pros, but it will be released to the general public next summer, making it Cerv\u00e9lo\u2019s first production cyclocross bike.<\/p>\n

While Cerv\u00e9lo says it draws much inspiration from the Cerv\u00e9lo R5 road bike<\/a>, this new cyclocross bike has a number of key differences thanks to Vos and Van Aert\u2019s input.<\/p>\n

The bike has a threaded bottom bracket, which is unusual for Cerv\u00e9lo, alongside a double seatpost clamp and plenty of tyre clearance. The geometry of the bike makes some concessions to cyclocross. It retains the same reach as the R5 road bike, but has a lower stack height.<\/p>\n

If you are particularly eagle-eyed, you may have spotted the Cerv\u00e9lo R5-CX being raced by Vos on the North American World Cup scene last month, where she won at Waterloo and Iowa.<\/p>\n

Threaded bottom bracket<\/h2>\n

What happens when your bike sponsor doesn\u2019t have a cyclocross bike, but you\u2019re a former world champ? It makes one for you, of course.<\/span><\/figcaption> Cerv\u00e9lo <\/i><\/span><\/div>\n

The R5-CX has a threaded bottom bracket<\/a>. This is notable for Cerv\u00e9lo, which has long stuck to its BBRight press-fit bottom bracket.<\/p>\n

The switch makes sense because cyclocross bikes are exposed to an awful lot of muck and grime, frequent washing and regular strip downs \u2013 all things that aren\u2019t particularly favourable with a press-fit bottom bracket.<\/p>\n

However, things aren\u2019t so straightforward. Cerv\u00e9lo has kept the asymmetric cup design on BBRight and opted for T47 threads. It uses an inboard cup on the left-hand side and an outboard cup on the right-hand side.<\/p>\n

This might be okay for the pros, but it might cause bottom-bracket buying headaches \u2013 as if we needed more of those \u2013 once the bike is released to us mere mortals next year.<\/p>\n

The bottom bracket on the R5-CX is 11mm higher than on the R5 road bike to create greater clearance over obstacles.<\/p>\n

D-shaped seatpost and double clamp<\/h2>\n
\""Close\"<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture><\/div>
The R5-CX has a double seatpost clamp.<\/span><\/figcaption> Cerv\u00e9lo <\/i><\/span><\/div>\n

The R5-CX gets the same D-shaped seatpost as the R5.<\/p>\n

The engineers at Cerv\u00e9lo say the R5-CX was originally going to have a standard round seatpost, as on the brand\u2019s \u00c1spero gravel bike<\/a>, but the D-shaped seatpost was requested by Vos and Van Aert. Presumably, this is because they are familiar and get on well with the D-shaped design on the R5 road bike.<\/p>\n

Another request from the two Jumbo-Visma riders was a double seatpost clamp. Cerv\u00e9lo says this is to \u201ckeep the saddle facing forward in case of a crash\u201d, which seems an odd statement considering a D-shaped seatpost won\u2019t rotate like a round one.<\/p>\n

A more understandable reason for the extra clamp mounted on the post is to ensure you get exactly the right saddle height after removing the post. Saddle height also isn\u2019t affected by the heavy bumps the riders are likely to put through the saddle during a race, for example when riding over rough ground or after less-than-perfect remounts.<\/p>\n

Pro spec<\/h2>\n
\""Marianne\"<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture><\/div>
The R5-CX is similar to the Cerv\u00e9lo R5 road bike, but incorporates design features requested by Vos and Van Aert.<\/span><\/figcaption> Cerv\u00e9lo <\/i><\/span><\/div>\n

The R5-CX is compatible with electronic drivetrains only and cable routing is internal, which Cerv\u00e9lo says is to minimise water ingress.<\/p>\n

The bike we have seen is fitted with a top-of-the-line Shimano Dura-Ace groupset<\/a> and wheels.<\/p>\n

For UCI-sanctioned cyclocross events, the maximum tyre size is 33mm, and this is what has been fitted to the R5-CX we have seen. The frame is said to have ample clearance to help shed mud and could likely take much larger tyres, but choosing to maximise that clearance with a bigger tyre size may affect the R5-CX\u2019s handling geometry.<\/p>\n

Not the first cyclocross bike<\/h2>\n

It\u2019s worth noting that while the R5-CX will be the first Cerv\u00e9lo production cyclocross bike, it\u2019s not the first \u2018cross bike the Canadian brand has made.<\/p>\n

That honour goes to the R3 made for Jonathan Page in 2007, which he rode to victory as the first American to win a cyclocross world cup podium.<\/p><\/body><\/html>\n
