Another episode of our Tech Q&A series has arrived and this week senior technical editor Warren Rossiter and technical writer Oscar Huckle, making his BikeRadar podcast debut, are here to answer your questions.<\/p>\n

With technical editor Tom Marvin as your host, Warren and Oscar warn against converting clincher wheels to tubeless and discuss the merits of tubeless road tyres<\/a>.<\/p>\n

Oscar weighs up whether tubeless tyre inserts<\/a> are necessary for cross-country mountain bike racing<\/a> before Warren predicts the rise of 3D printing, but not for bespoke components nor frames.<\/p>\n

The trio also reveal what they take on short and long rides alike, or in Tom\u2019s case, get riding pals to carry for him.<\/p>\n

Listen to the full episode below \u2013 or read on for a summary of Tom, Warren and Oscar\u2019s answers.<\/p>\n\n<hr\/><h3>Is it unsafe to convert clincher wheels to tubeless using two layers of

for a quick conversion?<\/span><\/figcaption><span class=\""im-image-caption"\"> <i>Joe Norledge \/ Immediate Media<\/i><\/span><\/div>\n<p><strong>Warren:<\/strong> \u201cI would say absolutely not. Hookless or hooked rims are made that bit stronger to account for the extra forces from the tyre being pushed out to seal against the rim.<\/p>\n<p>\u201cBut, I\u2019ve been sceptical about the issue of tubeless compatibility since hookless rims came on the road. If a tyre is built to the exacting ETRTO standards defined in tyre sizing then they should work.<\/p>\n<p>\u201cI\u2019ve run a set of apparently non-compliant tyres on a set of <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/tubeless\/"\">tubeless<\/a> rims for a year now and have had zero issues. They haven\u2019t rolled off, burped or even lost any air.<\/p>\n<p>\u201cI think some rims could take the extra force required to seal the tyre with two layers of rim tape.<\/p>\n<p>\u201cBut I would say that would impact the hooked hollow \u2013 the hollow in the rim where the tyre seats. The tape would build up the base of the rim and if you reduce those dimensions, then you might be looking at a blow-off or failure when riding.<\/p>\n<p>\u201cIf you have a decent set of <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/buyers-guide-to-road-bike-wheels\/"\">clincher wheels<\/a>, with <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-road-bike-tyres\/"\">good tyres<\/a> and light inner tubes, you are still going to have efficient rolling stock. I would suggest wearing out your wheels before upgrading to tubeless.\u201d<\/p>\n<p><strong>Tom:<\/strong> \u201cDo any rim\/tyre combinations work particularly well on the road?\u201d<\/p>\n<p><strong>Warren:<\/strong> \u201cBecause people were wedded to a narrow inner rim profile, that didn\u2019t make tyres easy to seat.<\/p>\n<p>\u201cNow people are broadening things out, so the inner average for a road rim is approaching more than 20mm. In gravel it is wider, approaching mountain bike standards of width.<\/p>\n<p>\u201cNow, seating a tyre is much easier.<\/p>\n<p>\u201cI remember dealing with tubeless rims when they first started to appear, which were still 17mm wide \u2013 a super-narrow rim width for a 23mm-wide tyre.\u201d<\/p>\n<p><strong>Tom:<\/strong> \u201cOscar, what\u2019s your experience of road tubeless? Have you got any top tips to make life easier?\u201d<\/p>\n<p><strong>Oscar:<\/strong> \u201cI haven\u2019t used road tubeless, but I\u2019m sold on it for <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-gravel-tyres\/"\">gravel bike tyres<\/a>. Tubeless allows you to run lower tyre pressure, removes the risk of pinch punctures and the ride quality is much better.<\/p>\n<p>\u201cI\u2019m not so sold on road tubeless. The standards for it aren\u2019t quite as finalised as for <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-gravel-bikes\/"\">gravel bikes<\/a> and <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/the-best-mountain-bikes-under-2000\/"\">mountain bikes<\/a>.<\/p>\n<p>\u201cIn terms of the question, I\u2019d say the same as Warren, that I wouldn\u2019t recommend converting clinchers to tubeless.<\/p>\n<p>\u201cAlthough the idea of double-taping a rim is good because it provides a better seal.\u201d<\/p>\n<hr\/><h3>Do I need tyre inserts for cross-country racing?

biking, but they are becoming more prevalent in <a href=\""https:\/\/www.bikeradar.com\/features\/routes-and-rides\/what-is-gravel-riding\/"\">gravel riding<\/a> and even on the road.<\/p>\n<p>\u201cIt\u2019s another layer between the tyre and rim that increases the sidewall stability because they provide further support and increased deflection, so the sidewall can move or fold if too much force is put on it.<\/p>\n<p>\u201cA tyre insert also allows you to run lower <a href=\""https:\/\/www.bikeradar.com\/features\/routes-and-rides\/what-is-gravel-riding\/"\">tyre pressure<\/a>.<\/p>\n<p>\u201cThe downside is extra weight, it\u2019s something else you\u2019re putting into your wheel. And it\u2019s rotating weight, which is more important on wheels.<\/p>\n<p>\u201cThe responsiveness of the bike is turned down a bit, too, by the added weight.\u201d<\/p>\n<p><strong>Tom:<\/strong> \u201cAnd because of the extra surface area on the inside of the tyre, you tend to have to use more <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/which-tubeless-sealant-works-the-best\/"\">sealant<\/a>.\u201d<\/p>\n<p><strong>Oscar:<\/strong> \u201cWhen I used to work in workshops, often we used to see the insert soak up the sealant.\u201d<\/p>\n<p><strong>Tom:<\/strong> \u201cGenerally, cross-country racers would try to use the lightest tyre they can get away with, so inserts are going to increase weight in there.<\/p>\n<p>\u201cSo would you say yes or no to tyre inserts for cross-country?\u201d<\/p>\n<p><strong>Oscar:<\/strong> \u201cI would say no, because cross-country is all about being lightweight. You could think about using a meatier <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/best-mountain-bike-tyres\/"\">mountain bike tyre<\/a> if the course is more technical \u2013 a downcountry tyre with a <a href=\""https:\/\/www.bikeradar.com\/advice\/buyers-guides\/mtb-tyre-carcass-construction\/"\">thicker carcass<\/a>.<\/p>\n<p>\u201cOr maybe have a look at what sealant they\u2019re using. That could be the problem if they\u2019re having a lot of punctures.<\/p>\n<p>\u201cAnd tyre pressure. There are a lot of factors to bear in mind. I think for XC it is overkill.\u201d<\/p>\n<p><strong>Tom:<\/strong> \u201cAs a counterpoint, on the rear wheel of the bike, if you are racing a more technical track, having a heavier-weight tyre provides that additional puncture protection that an insert also would offer.<\/p>\n<p>\u201cHowever, running a lighter tyre with a more supple sidewall does help with traction and comfort. Adding an insert might bring it to the weight of that more beefy tyre, but you should retain the ride benefits of the more supple tyre.<\/p>\n<p>\u201cIt\u2019s a bit of six of one and half a dozen of the other. But if they\u2019re racing more technical courses and want to protect against punctures, they could run higher pressures and take a hit on grip.<\/p>\n<p>\u201cOr using a heavier tyre with a more protected sidewall might be the way to go. If anything, to reduce the faff level and not have to use double the amount of sealant.<\/p>\n<p>\u201cAnd of course, these inserts aren\u2019t cheap. You are looking at \u00a350 to \u00a380 (from $60 to $100).\u201d<\/p>\n<p><strong>Oscar:<\/strong> \u201cSome of them can be a pain to set up as well.\u201d<\/p>\n<p><strong>Tom:<\/strong> \u201cThe answer to the question about considering tyre and rim widths is no.<\/p>\n<p>\u201cYou just have to match the insert width to your tyre width and make sure you pick the right one.\u201d<\/p>\n<hr\/><h3>I had a Canyon Ultimate and a <a href=\""https:\/\/www.bikeradar.com\/reviews\/bikes\/cyclocross-bikes\/focus-mares-ax-3-0-review\/"\">Focus Mares AX<\/a>, both with hydraulic Ultegra brakes.
