The German lightweight carbon craftsmen at Bike Ahead have revamped their mountain bike wheels with new wider, asymmetric carbon rims that they lace into some crazy light trail & race wheelsets. With the rise of ridiculously expensive e-mountain bikes they’ve even developed some eMTB specific components, including wheels to handle more weight & torque, plus new seatposts & handlebars. Then to top it all off, Bike Ahead has taken the unique tech integrated in their mountain bars and curled it up into the new RaceBar, an ultra light road dropbar.THEwheels XC-24 & XC-28Bike Ahead has essentially two approaches to mountain bike wheels – one of which is to develop ultra light carbon rims that they either lace into lightweight wheels in house or that they give to select trusted partners to lace into complete wheels. They don’t actually make the rims available to regular consumer or industry distribution channels so they can keep tighter controls of wheel builds to ensure quality & safety of the finished product.The latest carbon rims grow outward in width to include the new TheWheels XC-24 with a 24mm internal width and TheWheels XC-28 with 28mm inside, both with asymmetric profiles. Bike Ahead build both rims into wheeslsets with German Newmen hubs (standard or Boost), DT spokes & Prolock alloy nipples. The hook bead XC-24 (from 2200€) is geared towards XC & Marathon racing with weights as low as 1259g for a complete wheelset, and a rider limits of 95kg/210lb. The more aggressive XC-28 (from 2200€) gets a wide-radius hookless bead and is suited more for trail, all-mountain & even light enduro racing, with wheelset weights from just 1359g and a rider+gear limit of 105kg/230lb.biturbo-E & THEwheels-EBike Ahead is also getting into outfitting premium eMTBs with super light carbon wheels. They’s taken their classic 6-spoke full carbon Biturbo and amped them up for the added stresses of e-bikes. With their 27mm internal width, the Biturbo-E gets a modified layup to deal with the extra weight and additional torque and is available for both 27.5″ (1349g) & 29″ (1459g) setups. They still are silly light, and offer pretty much any hub interface your e-bike could need with a rider+gear weight limit of 115kg/254lb and a 3300€ pricetag.TheWheels-E keep the price a bit more in check, building off the same tech as found in the XC-28, beefed up for e-MTBs and the higher 115kg rider limit. Available with rims of either 27.5″ (1395g) or 29″ (1495g) diameter, both still build into super light trail-ready wheelsets for the same 2200€ price as the less reinforced trail wheels. And without any giant e-bike decals, that probably still makes them a reliable option for heavier or more aggressive trail & enduro riders looking to trim weight off the bike.THEseatpost SetbackBike Ahead’s latest post is the new TheSeatpost Setback, which takes their straight ultralight 2-bolt post and leans the shaft back for 15mm of setback. Adding setback to the post gave it a tapered profile at the head, while not affecting weight or price (or the 95kg rider limit). Available in 27.2 or 31.6mm diameters and 300, 350 & 400mm lengths, the 300€ post weighs as little as 112g (27.2 x 300) and tops out at just 145g (31.6×400). The post uses the same No Slip Application rubberized clamping area that requires lower clamping force to prevent slipping (this less risk of over-clamping & damaging the carbon.)THEseatpost & THEseatpost-EThe setback post joins the straight post, and now the new TheSeatpost-E which again uses teh same NSA clamp area tech and the same shaping with reinforced carbon layup for heavier e-bikes and increased likelihood of sitting on the saddle through the rough stuff. The TheSeatpost-E adds about 30-35g of carbon to the standard post, but increases rider limit up to 115kg/254lb for the same 300€ pricetag.THEflatbar-E & THEriser-ETheFlatbar-E & TheRiser-E are the two new e-bike additions that join the standard TheFlatbar & TheRiser (and the flat TheDi2, top left), offering again more reinforcement. Here the e-version is built to handle more clamping force, not just to resist heavier bikes & riders and the occasional (inevitable?) crash with the hefty eMTB, but also more device clamping on the bars like additional e-bike displays.TheFlatbar-E is available with 8.5°, 10° or 13° of backsweep (0 upsweep) in either 720mm (for the 8.5° only) or 750mm widths and 0mm or -9.5mm of ride thanks to the offset 31.8mm clamp. Weights range from 139-149g with a price of 230€. TheRiser-E bar gets 8.5° of back & 5° of upsweep to go with a 15mm ride for 240€. Both bar shapes feature the same rubberized NSA clamping area, option for UD or 3K finish, and generous 115kg rider limit.THEracebarLastly the new TheRacebar brings Bike Ahead more into the road and gravel sphere after last year’s wheel debut. The all new road drop bar takes the same ultra light tech in their mountain bike bars and shapes it for the road. The bars get a smooth compact bend – 80mm reach, 130mm drop, 5° backsweep. The incorporate the same NSA rubberized clamping area tech, which here works both to help the stem clamp the bar with lower force, but also helps keep your shifters from rotating while not having to over-toque the hoods down to the bar. At 400€ TheRacebar comes in 420mm & 440mm widths (440 coming about two months later) with weight starting at just 159g for a 95kg rider limit.All of the new components are available now direct from Bike Ahead or through regular retailers. Only TheRacebar is awaiting official release later in October 2017.Bike-Ahead.com
A new analysis of antibiotics doled out during US ambulatory care visits in 2015 indicates that more than 40% were inappropriate, and nearly 1 in 5 prescriptions had no documented reason for being written.In a study published yesterday in the British Medical Journal (BMJ), researchers looking at survey data on more than 28,000 sample visits to office-based healthcare providers in 2015—a sampling that represents 990.9 million visits nationwide—found that antibiotics were prescribed in 13.2% of visits. Of the 130.5 million antibiotic prescriptions given out during these visits, only 57% were for a bacterial infection or other condition for which antibiotics are commonly, and appropriately, prescribed.Twenty-five percent of the antibiotic prescriptions analyzed were deemed inappropriate because they were written for conditions, like upper respiratory infection, for which antibiotics aren’t indicated but are commonly prescribed. But 18%—representing roughly 24 million prescriptions—lacked either an appropriate or inappropriate indication.”When there’s no indication documented, it’s reasonable to think that at least some of the time, the prescription was written without an appropriate indication present,” lead study author Michael J. Ray, MPH, a researcher at Oregon State University’s College of Pharmacy, said in a university press release.The problem of undercodingTo determine whether the prescriptions were appropriate or inappropriate, Ray and his colleagues looked at the ICD-9-CM codes associated with each visit in which an antibiotic was prescribed. Only five of these codes, which are used by physicians to classify a diagnosis in a patient’s medical record for billing purposes, were included in the data from the 2015 National Ambulatory Medical Care Survey (NAMCS), a survey describing a sample of patients’ visits.The researchers note that even if more ICD-9-CM codes had been available to analyze, at best, 15% of the visits would have still lacked a documented indication for an antibiotic.The most common diagnoses reported among the “no indication” group were unspecified essential hypertension (11%), diabetes mellitus without mention of complication (8%), and other specified aftercare (7%).In analyzing additional patient data from the NAMCS records, the researchers determined that adult men (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.02 to 5.3), patients who spent more than 17 minutes with providers (aOR, 1.6; 95% CI, 1.1 to 2.5), and patients who saw non-primary care specialists (aOR, 2.1; 95% CI, 1.2 to 3.7) were more likely to receive an antibiotic without an indication.The analysis also found that sulfanomides (aOR, 4.9; 95% CI, 1.5 to 15.7) and urinary anti-infectives (aOR, 3.1; 95% CI, 1.3 to 7.6) were the antibiotics most likely to be prescribed without an indication.The study adds to a well-established body of research illustrating the problem of inappropriate outpatient antibiotic prescribing in the United States. The most widely cited study is a 2016 paper in JAMA that found that 30% of oral antibiotics prescribed for outpatients were inappropriate. Subsequent studies have indicated the proportion of outpatient prescriptions considered inappropriate may be even higher. But as Ray and his co-authors note, the previous estimates have typically relied on documented diagnosis codes to classify the prescriptions as appropriate or inappropriate. As a result, they believe those studies may underestimate the problem.”The primary objective of this study was to highlight the potential degree of misclassification that may occur due to under-coding,” they write. “Our work complements previous work in this area by assessing the potential effect that prescribing without a documented indication may have on the estimated burden of unnecessary antibiotic use.”They add that the identification of risk factors associated with antibiotic prescribing without a documented indication may be useful for antibiotic stewardship efforts.See also:Dec 11 BMJ studyDec 11 Oregon State University press release
BRISTOL, England (CMC):The prospect of representing the West Indies in his first-ever World Cup has been giving Sheldon Cottrell “sleepless nights”, the left-arm pacer has admitted.Cottrell said that turning out in the May 30 to July 14 showpiece was the fulfilment of a childhood dream and that he was fully prepared for the opportunity to compete on the world stage.“My preparation personally, has been going well. It’s a gradual build-up for me for the World Cup,” said the 29-year-old, who has played 14 One-Day Internationals (ODIs).“I’m looking forward to the first game. I’m having sleepless nights already, but that’s just anxiety on my side. I am ready, and the team preparation [has been excellent].”Cottrell has had a stuttering ODI career ever since his debut four years ago. His first two appearances came on a five-match tour of South Africa just months before the start of the 2015 World Cup in Australia and New Zealand.However, he never played again until two years later on the tour of New Zealand. He was selected for the World Cup qualifying campaign in Zimbabwe last March but managed a single match and played only one other ODI last year.His selection for the World Cup was somewhat fortuitous. A late addition to the West Indies squad as an injury replacement for the five-match series against England in the Caribbean earlier this year, Cottrell made an immediate impact in his first outing, snatching a maiden five-wicket haul to hand the hosts a pivotal victory in the second ODI in Bridgetown. A DREAM His overall performance in the series booked his spot to the World Cup, joining the likes of captain Jason Holder, Shannon Gabriel, Oshane Thomas, Andre Russell, Carlos Brathwaite and Kemar Roach in the pace attack.“For any young aspiring cricketers, the World Cup would be a dream for them, and it was for me,” the Jamaican said of his selection.“Growing up in Jamaica, I couldn’t foresee this coming, so being selected [was a dream for me]. I got no handouts, I’ve done well, I’ve been rewarded, so it’s just for me to continue my hard work.”He added: “I’m about 90 per cent [happy with my bowling at present]. I am very much hard on myself when it comes on to my bowling. There’s always room for improvement, and I mark myself hard, so I’m about 90 per cent and, I’m hoping I can get to a hundred.”One of the least experienced players in the squad, Cottrell said it was important that he learnt as much as possible from his more seasoned teammates in coming weeks.The West Indies open their World Cup campaign against Pakistan at Trent Bridge in Nottingham on Friday.
