Tire Evaluation – Surly Larry

The Surly Larry is a bicycle designed especially as a leading bicycle for fat bicycles. It comes with a string of dart shaped knobs and small domes in between the knobs which allegedly combine grip and drift control. This is an overview of this folding 120 TPI variant because model is the lightest and also needs to be the quickest. A more affordable 27 TPI wire bead version of this scooter is accessible also.

Exactly enjoy the 45NRTH fat bicycle tires, the Surly fat bicycle tires are costly. The high costs put high expectations so I am actually excited about analyzing this tire to find out whether the Surly tires really are worth the cash. I could not find much info regarding rubber chemicals, threading layers, reinforcements or alternative specifications of these Surly tires so let us just examine this drill and determine where it ends up.

All rolling resistance evaluations are conducted on our rolling resistance test system. Read our The Evaluation page for a detailed explanation about how we examine tires.

Do not forget to have a look at the review pages to make it simpler to compare all of tires which were examined.

A number of the lean technical information regarding the Larry is that it ought to have a burden of near 1256 g. My sample comes in at 1212 g and that makes this one of those few tires which really weigh significantly less than the specified weight. The measured casing diameter onto a 65C rim with an air pressure of 16 psi is 93 mm. The shoulder knob into shoulder axis thickness is 90 mm. The 3.80 score on this tire appears to make sense as it is somewhat more compact than the 4.00 ranked tires.

The middle and shoulder hinges on the Larry all have exactly the identical height of 4.5 mm that's a centre of the package knob elevation to get a fat bicycle tire. The sidewalls have a mean depth of approximately 0.9 mm that also matches the center of the bunch.

Rolling resistance of this Larry is not very low, but it will outperform the both expensive tires out of 45NRTH. In comparison to the best performing tires, over 10 watts is dropped per scooter in the very low air pressure of 8 psi / 0.6 pubs. At higher air pressures, the distinction is a little smaller but still important.

Because most Surly tires appear to use the exact same structure and likely come from the exact same mill, I dont anticipate their other tires to magically perform far better at the rolling resistance evaluation. For the money that they request this scooter, I believe it disappoints.

Astonishingly, the Larry does not work that well in the puncture resistance evaluations either. With dozens of 6 at the tread puncture evaluation and 4 points at the sidewall puncture evaluation, it comes in at the base of the package.

The Surly Larry doesnt impress me at all. A couple of years back this scooter may have been a fantastic alternative, however other tires have become available that significantly simplifies this particular tire. If you prefer to operate your tires at very low air pressures, then its crucial that you have tires that give a minimal rolling resistance. When compared with this Surly Larry, the very best rolling fat bicycle tires may save 25 watts of electricity for a set of tires.

I speed the Surly Larry 3 out of 5 since it does remain under 50 g per bike in 8 psi / 0.6 pubs and outperforms a few tires in our evaluations.
