With its 30mm deep, 24mm wide rim the Lark Tubs are at home on or off road. The high strength, wide rim supports tubular tyres while being deep enough to offer some aerodynamic benefit on the road and repel mud build-up in cyclocross.
Brake setup with calipers or cantis is easy on the ultra flat 9.5mm wide brake track for smooth consistent braking in all conditions.
The Lark Tub wheels are built with 24 spokes front and rear, with the rear being arranged in our usual super-strong 2:1 configuration which uses 16 spokes on the highly stressed drive side, and 8 on the non-drive side. This results in very even spoke tensions and a strong, durable wheel. Hubs are our “standard” J-bend road hubs which use large long-lasting stainless steel bearings with excellent sealing while maintaining a low weight of 85g front / 216g rear.

Buy tyres with your wheels and we’ll fit them for free
We’ve been riding the IRC Formula RBCC tubeless tyres for sometime, initially intrigued by the Rice Bran compound we are now pleased to offer IRC tyres on all our wheelsets.
The 25c IRC tyres come up true to size at 25.5mm when fitted on our Lark light wheels. Choose the RBCC for general riding and racing and the X-Guard for training and winter riding. If you prefer something wider try the 28c versions of these tyres in our tyres section.
