It's interesting that you bring up tandems. Tandems do have their own
requirements – they should not react much to weight shifts, since the
captain cannot anticipate when the stoker reaches for a water bottle or
scratches their nose – but the best tandems are as nimble at speed as a
good
I have run into one specific tire with a bead problem, and that is the
Challenge Strada clincher (open tubular). On my daughter's Kinlin rims,
I can't run the pressure up to 90 psi, but that is not a problem, since she
can ride at 75. On my Campy (Omega) Moskva rims, this tire will not bite,
One of the long-held beliefs of cyclists is that bottom bracket drop
affects the handling. It makes sense - you lower the ride, and the bike
should turn better. However, you need to look at what the important
variable is: It's not the BB drop, not even the BB height, but the center
of gravity
Jan,
A slight point of order, the chainstays on the Surly Long Haul Trucker are
460mm. And the wheelbase, depending on wheel size, varies from 1036mm to
1105, both on the 26 wheel version. From what I can quickly figure out,
the wheelbase difference on a medium sized bike (ca. 58-60cm) is closer
You are right! The LHT does have LONG chainstays... Most touring bikes I
have measured were classic machines that had shorter chainstays than that.
My old Mercian tourer had a wheelbase of 1028 mm. Of course, the main
determinant of wheelbase is top tube length - a large frame will have a

Lacking any hard data, we can only play with the numbers. 3 mm is
25% of 12 mm, which is probably the average difference in bottom
bracket height between cyclocross and road bike bottom bracket
heights. People have argued that road bikes noticably turn better than
cyclocross bikes due to this
Thanks Toshi and thanks Jan. I liked everything else about the Hetres and
I'm going to give them another shot at some point. My bike is 58cm but
there is a 54cm Polyvalent kickin around that my girlfriend rides. Maybe I
will put em on that bike and see how it feels. I will report back if its
I picked up some new Hetres for the Hilsen last winter and mounted
them on my synergy rims. I used an extra layer of rim tape to compensate
for the deep wells. I tweaked things as best as possible and took them for
a spin. I thought the bike handling was kind of twitchy. I took the
Hi Mike,
I've used both PariMoto tires as well as Hetre tires (albeit not on
the same bike). I've liked them both, although the Hetres definitely
have a longer life tread.
I guess if the tire pressure is too low, it might feel squishy and
off, but you're likely to have accounted for that.
The
A poorly seated tire will wobble - you'll notice it when looking at the
tread as you spin the wheel. You might also get a thump-thump as you
ride, if it's severe.
Regarding the handling difference between Hetre and Pari-Moto you describe,
we've never noticed anything like it. At the cornering
The problem lies with the rim, not the tire. All tires will fit poorly on
the Synergies, whether 650B or 700C. You can make it work – I use the
Synergies on my own bike – but the tire doesn't seat automatically as it
should. If you don't have problems, then you are mostly fine. There still

Thanks a lot. I feel better.
Mine mounted great on my rims. No problem.
So good to know they are a safe match.
