Challenge Hand Made TLR - Chicane/Grifo/Baby Limus/Limus 33mm - PAIR
We have been riding Challenge's HTLR tyres since their launch and they definitely add to the tubeless game for CX - but we do not think they challenge tubular's dominance at the performance end of the sport
Read the full review here but in summary -
"At 22psi rear and 20psi front, with the Tubolight liners, HTLR perform well and I'm confident they will not burp. They grip better than vulcanised versions (with similar tread) and definitely offer pinch puncture resistance compared to open tubular clinchers with a latex tube.
If you are happy to put up with a little sealant seepage (they've held their air just fine) and accept that they will take a few rides to bed the bead in, then Challenge's HTLR used with a Tubolight liner are recommended as a premium tubeless option"
If used without a liner, the tyre pressures required for reliable tubeless performance do not allow the benefits of the handmade materials to be felt
Take a look at our recommended Tubolight CX liners
Available as pairs only
We say UCI legal on up to a 20mm internal width rim (Challenge say up to 23mm internal)
UPDATE - We've been testing HTLR on a soon to be released LOWMASS Super Light CX Race Carbon Tubeless wheelset with hookless rims, they have proved to be much more reliable with these rims. There has been no sealant seepage at all and have been used all winter without liners, at tub tyre pressure. They are looking like a great option for those who don't like the idea of tubulars - watch this space...
If you don't already own one, we recommend getting a Challenge Bead Seating Tool, it makes life a lot easier with these tyres, and any tight tubeless/clincher tyres
"The best all-around cyclocross tire ever created excels in wet or dry, soft packed, rocky and root-infested courses, grass, and more. The Grifo features fast rolling knobs and a center section that offers excellent pedalling and braking traction.
Challenge H-TLR tires meet the new ETRTO and ISO standard and are hookless compatible.
Size 33mm - Designed to be complaint with UCI rules with most rims having an internal rim width up to 23mm.
Tyre pressure - 1.8 - 2.5 BAR / 26 - 36 PSI
Compatible with Hooked or Hookless rims
Handmade TLR are best combined with the Challenge’s SMART Tubeless SEALANT, which protects the natural properties of its components for a longer lasting performing tire, while further enhancing puncture protection and air tightness.
Handmade TLR (H-TLR)
New Handmade TLR (H-TLR) perform better than any vulcanized tubeless system! Challenge Handmade TLR are made from the same materials and processes as our handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around a aramid bead to form a tire that fits on a tubeless rim.
The HTLR is molded flat, not in a horseshoe like a vulcanized tyre. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A normal vulcanized tubeless tire is molded in a U-shape to make the sidewalls rigid so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection. The new Challenge H-TLR is anything but normal. Where vulvanized is stiff, high rolling resistance and uncomfortable to ride, the new H-TLR maintains the soft supple qualities of all Challenge Handmade tires but sets up with a sealant on TLR wheels.
A bead-to-bead inner coating gives added puncture protection to these new H-TLR tires and greatly reduces any air pressure dissipation. Enhanced longevity has been gained with the addition of an aramid bead protection strip, to reduce rim chafing.
The unique Challenge Handmade Tubeless system is the closest thing to a high performance Handmade Tubular that you can fit on a tubeless Ready clinchers."
