![]() This makes perfect sense, especially useful for technical descents.īecause gravel bikes are designed for off-road adventures most will have provisions for mounting mudguards, front and rear pannier racks and multiple bottle cages. Some gravel bars are slightly flared and some will be substantially flared (almost like moustache handlebars).ĭropper seat posts are also becoming quite common on high-end gravel bikes. This wider grip allows for greater control on technical descents. In fact my old 1990 Dawes Galaxy has slightly flared bars. This design was first seen on touring bikes back in the 70’s and 80’s. Finishing kitīecause of the need for greater control (particularly when descending) gravel bikes generally have flared drop handlebars and shorter stems.įlared bars have the drop bar portion wider than the maximum bar width at the hoods. Larger volume tyres with lots of tread are also good for riding an e-bike in the winter. Gravel tyres will, of course have a greater weight and rolling resistance which will be especially noticeable when riding on tarmac, but I’ve ridden quite a few and I feel that for the every day rider this is negligible. A typical gravel tyre will be 650b x 47 and most can be run tubeless, meaning they can be used at the preferred lower pressures without worrying about getting pinch flats. The main advantage of 650b is the slightly smaller diameter and wider rim, make for a more robust wheel that is capable of handling the rough and tumble of off-road riding. Wheels and TyresĪ lot of the latest gravel bikes will have 650b wheels fitted although 700c is still in widespread use. The main manufacturers of these groupsets are Shimano, with their GRX gravel bike specific groupset, and SRAM with their Apex and Rival 1 x hydraulic brake groupsets. 1 x drivetrains are almost universal on higher-end mountain bikes and gravel bikes. One of the main benefits of this kind of set-up is simplicity and a small weight saving. These typically have a 42t front chainring combined with an 11-42t rear cassette. ![]() This gives the rider a much lower gear for tackling steep technical off-road climbs without having to get out of the saddle (and thus loose traction on the rear wheel).ġ x Drivetrains are also very common on gravel bikes. A typical road bike will have a 50/34 compact crankset with an 11-28 rear cassette, whereas a gravel bike will likely have a 48/32 or 46/30 sub-compact crankset combined with an 11-32 or 11-34 cassette. Like their regular counterparts, electric gravel bikes typically use either sub-compact cranksets or 1 x gearing. 650b wheelsets shod in wide ‘gravel specific’ tyres are also common. Hydraulic disc brakes are also fitted as standard to all electric gravel bikes. Typically gearing will be lower, and the use of sub compact cranksets or 1 x drivetrains is the norm. – It’s not uncommon to see gravel bikes with 47mm wide tyres.Ĭheck out 10 of the best electric hybrid bikes under £3000 Gravel bike componentsĪs they are designed to be used for road and off-road riding, gravel bikes tend to use components suited to both. They will also have more frame clearance for wider tyres. Typically a gravel bike will have a much more relaxed frame geometry more akin to that of a mountain bike, but with the advantage of being much quicker, particularly on compacted gravel surfaces and forest trails. What designers have done is taken the best design cues from all three and integrated them into one. The gravel bike is an amalgamation in design from various disciplines – mountain, road and cyclocross bikes. ![]() Gravel bikes first became popular in the United States, this is due in part to the thousands of miles of deserted gravel tracks crisscrossing the vast wilderness, and the fire roads which were designed to allow access to fire trucks in remote forest plantations. Anyone who has every ridden a bike with slick 25mm tyres on an average British road will be aware of the ever present dangers of poorly maintained surfaces. If you commute by bicycle anywhere in the UK, it is unlikely that your daily commuting route will be free from potholes, road debris and other road surface hazards.
