|What's the best pump head for the Silca floor pumps?||Ken of Fresno|
Nov 9, 2002 10:12 AM
|I have a Silca Super Pista floor pump and the gasket in the head has worn out. Instead of just replacing the gasket I'm thinking about switching to the presta only head, becasue the presta/schrader head that came with the pump has always had a tendancy to slide off the valve (even more so now that the gasket is worn). I remember using the presta only head when I worked in a bike shop years ago and never having a problem with it. Any thoughts about the Silca pump heads or alternatives?
Thanks for your input,

|Yeah, I've found those presta/schrader head to be problematic. I haven't had a problem with my presta-only head in (yow--getting old here) 18 years.|

|I replaced mine with a Topeak Smarthead kit. It grips almost too tight...I ripped out a valve stem once. Nicest feature is that it works on both presta and shraeder stems w/o rearranging parts.
If I was only pumping pretsa valves, I might go back to the old Silca presta-only press on head. I recall that working fine, and not until after I retired it did I read where you were supposed to press it on, then give the outer ring a twist to squish the gasket around the stem. I found that gravity worked just fine...if I kept the stem at the bottom of the wheel, it gripped OK without the twist.
But I think I have may have created a serious moral and ethical dilema. Isn't putting Topeak on a vintage Silca as bad as hanging Shimano on a vintage Masi?

|There's no heresy in that. I did the same thing, but it was with the Topeak standard head. It's not very smart. I agree with you about the smart head having a bit too much grip though. I have a minipump with that head and don't like it much either.|

|and put the Topeak Smarthead kit on...I pump to 110psi front and 130psi rear; and the Silca heads wouldn't stay on...the Smarthead works fantastic....and on the local bike rides, there's occassions when someone (a newbie) wants to know if I have a pump and sometimes they have a Schrader valve...so I'm glad I can help.....|

|On all the way to 150 on my Vred's....the secret is to loosen top piece of Silica head so there is no friction putting pump head on. Then tighten down around valve stem. More work than a smart head but I'm attached to my old pump. Also people don't replace grommet often enough. I have often had people walk in my shop unhappy and walk back out with there silica + new grommet. They kinda like I charged them .99 and showed them a trick or two.|

|I too own a Silca pump. Love it. Don't want any other type. Never seen the replacement grommet advertised. Does anyone know where I can get one. BTW the gravity and laugh all you want put a little spit on the grommet then insert it over the presta. Any feedback on the grommet replacement appreciated...Don|

|They are cheap (less than a buck)and not sure where you could find them online BUT any local shop with a QBP (quality bicycle parts) account can order them. Whether or not you can find one willing is another matter. There are mutliple size pump heads so make sure you bring old grommett in when ordering.|

|that you should oil the diaphram at least every 3 years....DON'T put oil down the barrel; remove the diaphram and apply enough oil to make it pliable again, not saturated. I bought mine in 1980, and have only had to replace the diaphram once (guess who didn't oil the diaphram??). A coat of wax on the barrel will also help it from looking like a garage-sale item.....|

|If you oil the leather washer, you run the risk of the oil being aerosolized into the inner tube, resulting in premature failure of your inner tubes. Use grease on the leather - it will last longer (several years, a decade?) and won't pass along into your tires as you pump them up.|

|Topeak makes a nice little conversion kit for about $15 that will handle both Presta and Schraeder - no more screwing around taking things apart or fiddling with worn out Silca stuff. Converted mine several years ago when the kit was a double headed setup, now they make a universal head. It's a huge improvement and makes my pump the one of choice when we go any where - it always works.|
|Had one - changed it for a Blackburn||Eager Beagle|

|The rubbers wore out and I couldn't get replacements. So a got a Blackburn "T" double headed one - push and turn to lock, together with the tubeing. Presa one end, Schrader the other.
Just pulled the old tube off the bottom, slipped the new one on, and yanked up a zip-tie to hold it fast - works a treat and the head locks on/comes off in a split second - much easier that all that screwing on and off with the origional. Great bit of kit.
Better yet, Blackburn sent it for free after I rang them up to ask where I could get one - you can't beat that.
