Fork-mount roof bike rack: compatible with QR, thru-axle and Boost
The problem with a fork-mount roof bike rack is never strength: it's the axle standard. This block solves the compatibility issue right out of the box, coming with four sets of conversion adapters covering classic quick release, modern thru-axle and Boost forks. You place the fork, tighten it, and the bike doesn't budge. A car roof fork mount that doesn't require buying a new part at the first bike change.
A compact anodized fork block, in black, red or silver
110 x 38 x 58 mm, 180 grams: the block fits in your hand. On the bar, it takes up the space of a closed fist and is completely forgotten once the bike is unloaded. Three anodized finishes are offered — discreet black, bold red, raw silver — to match the car roof bike mount to the color of the bars rather than having to make do.
With the front wheel removed, the bike gains several centimeters of clearance. Less height, less noise, less lateral movement in corners: transporting a bike on roof bars changes when the fork is locked instead of the frame being strapped.
Aluminum alloy and quick-release pin: the block's mechanism
The body is machined from an aluminum alloy: no plastic parts are involved in the load-bearing chain, unlike many budget mounts that cut corners. It is tightened with a quick-release pin, exactly like a hub lock, with tension adjustment via a knurled nut. The stated 20 kg load capacity easily covers a mountain bike, gravel bike or road bike — make sure to check the load limit of your own bars, which is almost always the limiting factor. The four conversion caps make this thru-axle fork mount a part that will follow your next bikes.
- 4 sets of adapters included — quick release, thru-axle and Boost forks covered.
- Aluminum alloy body — 110 x 38 x 58 mm for only 180 g.
- 20 kg load capacity — comfortable for a full-suspension mountain bike.
- Quick-release pin tightening — loading and unloading in less than a minute.
- No contact with the frame — carbon tubes and delicate paintwork remain intact.
- Three anodized finishes — black, red or silver to match your bars.
Mounting this fork mount on your roof bars
The block is bolted by its lower plate to a crossbar; the mounting screws are not provided, choose them according to your bar's profile. Another very common use: screw the mount onto a board placed in the trunk of a SUV, to transport the bike inside without it lying flat. Allow fifteen minutes for the installation of a roof bike rack and keep enough space between the mount and the rear opening. Bar compatibility should be checked before installation.
Which adapter to choose according to my fork?
The measurement is read on the axle itself or in the fork manual: the first number gives the diameter, the second the spacing between the legs. A recent mountain bike is generally 15 x 110 mm — the famous Boost standard — a disc road bike 12 x 100 mm, an older bike with a 9 mm quick release. The four caps provided cover the majority of cases; measure with a caliper rather than estimating by eye before mounting your roof fork block.
