About this deal

Should one consider a rule of thumb to be that a chainset should not be more than 1 speed higher than the your groupset's speed?

Fitting a crank with smaller chainrings means you have to move your front derailleur down, and this is something to look out for before buying any sub-compact cranks. My gravel bike just had the necessary 8mm of adjustment, but I'm pretty sure the front derailleur mount on my road bike is too high. Alternatives Most road bikes come with a double chainset, meaning that you have two chainrings. The larger chainring gives you bigger, harder to turn gears that move you further per pedal revolution – so it's suitable for higher speeds – while the smaller chainring gives you gears that are easier to turn but move you a shorter distance per pedal revolution – so it's suitable for lower speeds, including riding uphill.Shimano offers four levels of 1×12 drivetrain, from Deore through SLX, XT and up to the top-of-the-range XTR groupset, though this is expected to change with the introduction of Shimano Cues. The latest crop of gravel specific road drivetrains offer lower gearing than a typical road bike. Groups like Shimano GRX, SRAM Force AXS Wide and Campagnolo Ekar are designed to help you deal with steep dirt roads with loose surfaces as best as possible through wide range gearing. In the case of 2x gravel groups, the new “sub-compact” cranksets have smaller chainrings than the common 50/34 compact rings many road bike come with. New gravel friendly road cranksets include the 46/30 Rotor, 46/30 FSA Adventure, 48/32 Praxis Zayante, the 46/30 Shimano GRX RX FC600 and the 48/31 Shimano GRX FC-RX810. How do you know if this lower gearing is for you? A Brief History of the Compact Crankset Tanpan cable converter at the front near the 105 rear shifter/brake (away from the road and contamination). For the moment the big three — Shimano, Campagnolo and SRAM — claim to have no plans for super compact chainsets.

In contrast, SRAM’s 11-speed road bike cranksets have five arms, distributed evenly and with one chainring bolt screwing into the rear side of the crank arm. The triple chainring, which was largely killed off when the compact arrived, still has an advantage over a standard compact with its granny ring, but Bellin suggests that with the advent of the super compact chainset the triple is definitely dead this time. Swapping chainring sizes is possible, but compatibility needs to be considered. Simon von Bromley / Immediate MediaTriples have fallen out of favour thanks to the marketing bods, mainly thanks to SRAM. The 1x trend (which really means having to buy a stupidly expensive cassette only to find you still don't have a tall enough top end or low enough bottom end) has only made triples seem even less 'cool'. But I used to spend 95% of my time in the 39T and never found a third chainring to be a problem and I couldn't GAF about being thought of as 'cool'. It's time to kill the macho bullshit chainring thing and just fit what works for the riding you do. The wide-range gearing offered by sub-compact chainsets means triples have almost vanished from road bikes. We've seen two in the last couple of years, both on touring bikes.

He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history.Optimized to each size separately. 30T- 9% ; 32T - 8% ; 46/48T - 10-11.2% ; Timing of 108 -110.5° after TDC (top dead center) - Ideal for climbing. Patent Pending Praxis Works make a 48/32 sub compact chainring set on a 110bcd, which means you don't need to buy a specific sub compact chainset. The inner mounts on the outer, as it's the BCD that dictates the smallest size inner chainring possible. The Sugino OX chainset comes in a range of chainring sizes with the smallest being 30/44, to get the 28t granny I bought their standard 9 speed 28t chainring and chamfered the outer edges of the chainring bolt holes to get proper clearance from the frame - you simply copy the chamfers on the 30t ring. Works a treat as the pins and ramps are on the 44t chainring. The Sugino chainset has performed well.
