We still have stock of sizes \\#1, \\#2, \\#3, \\#5, \\#9 and \\#11  \nThe Raven Twin Mk2 frames have the suffix “A”.  \nEach of these options, were available in a choice of 3 different colour powder coat finishes. We still have stock of sizes \\#4A, \\#7A and \\#12A  \nChild back tandems, sizes\\# 1 and \\#2  \nThese frames are direct lateral child back tandems; that is to say that they are designed for very small stokers. The two sizes are to accommodate either a short or a tall pilot (Mum front and Dad front?) I have designed these frames to keep the overall length as compact as possible, whilst providing sufficient “growing room”, to allow most children to be able to enjoy riding tandem up to an age, where they are old enough (and hopefully, sensible enough, having learned road craft from an early age) to be allowed to keep up with the rest ofthe family on their own solo bikes. They will certainly be fit enough! It is difficult to give an age range... we all know 6 feet plus eleven year olds and sub-5 feet adults. Whilst the base tubes are short, compared with the other sizes in the range, they are no shorter than some of yesteryear’s double adult racing machines!  \nThe compact, stiff frame, enables these machines to be ridden solo... making the “school run” a very attractive proposition! Indeed, it is reported that such lucky children, are considered by their peers, to be very “cool”.  \nPlease remember that these are high quality frames, this combined with the super durable Rohloff hub, will ensure a very strong resale, or trade-in value; the inevitable capital outlay, is more than offset by savings on fuel, servicing and time, compared with driving to school. If it is to be used for leisure only, it is a very small price to pay foryour shared experiences, whilst giving a child the best possible opportunity to become a cyclist, in their own right.  \nSize \\#3 (S/XS)  \nThis size has the lowest front and rear stand over heights that we can provide, with this style of double adult tandem. This size would suit much shorter than average male (or slightly shorter than average female) pilots and shorter than average female stokers. There weren’t as many crews, who wanted this size tandem as we’d thought!  \nSize \\#5 (M/M)  \nThis size will suit average size male (or taller than average female) pilots and female stokersof average height.  \nSize \\#9 (M/M)  \nLike size \\#5, this size is also suitable for average size male (or taller than average female) pilotsand female stokers of average height.  \nSize \\#11 (L/L+)  \nPilot and stoker both need to be tall, to ride this size. The front top tube and the base tube, are both really long.  \nThey’re long enough even for an average sized male stoker to be really comfortable.  \nWhen you’re both tall (which you need to be, to ride this size!) frame stiffness is really important. Consequently this size is especially suitable for high performance cycling, as well as obviously being suitable for expedition use.  \nSize \\#4A (Small Medium/Small). This was avery popular size and we sold out of the original frames in size \\#4, very quickly. Size \\#4A will suit shorter than average male (or average sized female) pilots and slightly shorter than average female stokers.  \nSize \\#7A (S/M) This size suits atandem crew, where the pilot is not only short but possibly shorter than the stoker. It’s usual for the partner, with the greatest upper body strength, to be on the front, but we’ve also sold many of this size to (or for) average size female pilots with blind male stokers. This size is perfect for an average size female pilot and an average size male stoker.  \nSize \\#12A (L/M).  \nThe pilot needs to be taller than the average size male and the stoker needs to be at least as tall, as the average siz","cbCaiaoxyex6Y6hU","https://ap.wps.com/l/cbCaiaoxyex6Y6hU","pdf",281163,"English","# Frame Sizing\n## Mk1 and Mk2 sizing options\n## Child back tandems (sizes #1, #2)\n## Double adult tandem sizes (#3, #5, #9, #11)\n## A-sizes (#4A, #7A, #12A)\n## Model specification table","[{\"question\":\"What does the “A” suffix mean for Raven Twin Mk2 frames?\",\"answer\":\"The Raven Twin Mk2 frames use the suffix “A” for the listed A-size options.\"},{\"question\":\"Which Raven Twin sizes are designed for child back tandems, and for what rider height profiles?\",\"answer\":\"Sizes #1 and #2 are direct lateral child back tandems, intended for very small stokers, accommodating either a short or a tall pilot.\"},{\"question\":\"How should riders choose between the compact smaller double adult sizes and the long larger size #11?\",\"answer\":\"Smaller sizes target shorter than average pilots/stokers with lower stand-over heights, while size #11 requires both pilot and stoker to be tall due to long front top and base tubes and greater stiffness needs.\"}]","Raven Twin - Issue 29 - AUTUMN 2017 | PDF",1791841891]
